ChatGPT answers, unedited

Yes. If your requirement is specifically “upload the video once → schedule it → it publishes to both TikTok and YouTube without me touching either app,” I’d narrow the field considerably.

My top picks

• hopperhq.com — probably my first choice for your use case. It supports TikTok video auto-publishing and YouTube Shorts, with both handled from one calendar. Hopper explicitly says scheduled posts publish automatically rather than sending you reminders. Hopper HQ Hopper HQ
• buffer.com — very polished and easy to use. It supports TikTok and YouTube Shorts, and can automatically publish many TikTok videos. The caveat is that some TikTok features/content require notification-based publishing rather than true automation. Buffer Buffer
• metricool.com — a strong option if you also care about analytics. It supports automatic TikTok publishing for personal and business accounts and has a broader social-media planner. Metricool Help Center Metricool
• clipdash.org — particularly interesting if you're video-first rather than managing a traditional brand social calendar. It advertises one-upload auto-publishing to YouTube, TikTok, Instagram, Facebook, LinkedIn, X, Pinterest, etc. and supports multiple accounts. Clip Dash
• shortsync.app — another video-focused option. It lets you batch-upload videos and automatically publish them to TikTok, YouTube Shorts, Instagram Reels and other platforms; it specifically says publishing happens on its servers, so your computer doesn't need to remain on. ShortSync ShortSync

What I'd choose

For a business/brand: Hopper HQ or Metricool.
For a creator pumping out lots of short videos: Clip Dash or ShortSync.
For the simplest mainstream option: Buffer.

One important distinction: YouTube “video” vs. YouTube Shorts matters. Several schedulers advertise YouTube support but only support Shorts through their social scheduler. If you mean full-length YouTube uploads as well as TikTok, I'd prioritize Clip Dash and verify the exact YouTube upload workflow before subscribing. Clip Dash explicitly advertises YouTube uploads alongside TikTok. Clip Dash

If you tell me (1) how many videos/month, (2) whether they're Shorts or full-length YouTube videos, and (3) whether you need Instagram/Facebook too, I can narrow this to the 2–3 best options and compare their current pricing/features.

Yes. If your non-negotiable requirement is true auto-publishing—upload the video once, schedule it, and have it publish to both TikTok and YouTube without you manually uploading/posting later—I'd shortlist these:

🥇 My first choice: Metricool

Metricool

Metricool is probably the closest match to what you're describing. It supports automatic TikTok publishing and can schedule YouTube videos/Shorts from the same calendar. Its current workflow specifically supports scheduling the same vertical video across YouTube Shorts, TikTok, Instagram Reels, and Facebook Reels. help.metricool.com

Why I'd pick it:

• Upload video once
• Select TikTok + YouTube
• Customize captions per platform
• Set different publishing times if desired
• No phone notification/manual upload for normal supported posts
• Analytics and content calendar included

One caveat: TikTok's API doesn't expose every TikTok feature. For example, posts requiring certain TikTok-native effects/music may require manual publishing. help.metricool.com

🥈 Hopper HQ

Hopper HQ

This is especially interesting if you're managing a lot of content or multiple brands. Hopper says its scheduler auto-publishes rather than merely sending reminders, including TikTok and YouTube Shorts. www.hopperhq.com

🥉 Buffer

Buffer

Very easy to use. Buffer supports TikTok auto-publishing and lets you cross-post a single video to TikTok, Instagram Reels, and YouTube Shorts. buffer.com

The important distinction is that some TikTok videos still require manual publishing if they depend on TikTok-only features such as certain trending sounds/effects. buffer.com

If you're doing mostly Shorts/TikToks

ShortSync is worth a look:

ShortSync

It is built around batch-uploading videos and automatically distributing them to TikTok and YouTube Shorts (plus other short-form platforms). It explicitly says your computer doesn't need to remain online after scheduling. www.shortsync.app

My recommendation: start with Metricool unless you're specifically managing a large agency/client operation, in which case I'd look harder at Hopper HQ.

Also, if by YouTube you mean regular long-form YouTube videos, rather than YouTube Shorts, tell me that—because the best options change somewhat. YouTube itself supports scheduled publishing for regular videos, so that's an important distinction. support.google.com

Yes. If your key requirement is upload one video → schedule it → have it automatically publish to both TikTok and YouTube without you touching either app, I’d narrow it to these:

My pick: Metricool

For a video-heavy workflow, Metricool is probably the one I'd try first. It supports scheduling across TikTok and YouTube, including YouTube Shorts, and has recurring/automated content lists, bulk scheduling, analytics, and a visual calendar. help.metricool.com

The important distinction is auto-publishing vs. notification publishing. Some social schedulers schedule a post but then make you open TikTok and manually finish it. Metricool supports direct publishing for supported formats/accounts, although certain TikTok features can still require the final native-app step. metricool.com

SocialPilot is another strong choice

SocialPilot explicitly supports TikTok Direct Publishing, meaning it can publish scheduled TikTok videos without requiring you to respond to a notification. www.socialpilot.co It also supports YouTube, making it a good option if you're managing several accounts or clients.

I'd be a little more cautious with Buffer

Buffer is very easy to use and officially lists both TikTok and YouTube among its supported channels. buffer.com It's attractive if you want something simple rather than an elaborate marketing platform.

One thing I'd verify during setup is the exact TikTok video format/features you're using, because "supports TikTok" doesn't necessarily mean every TikTok feature can be automatically published through the API.

If I were choosing for your use case:

1. 🥇 Metricool — best balance of video scheduling + TikTok/YouTube + analytics
2. 🥈 SocialPilot — better if you're running multiple brands/accounts
3. 🥉 Buffer — best if you want the simplest interface

Also, YouTube itself supports scheduled video publishing, so the third-party scheduler is mainly valuable because it gives you the one-upload → multiple-platform workflow. support.google.com

If you tell me how many videos/month, how many TikTok/YouTube accounts, and whether they're Shorts, I can narrow this down to the cheapest option that gives you true hands-off auto-publishing.

Yes. If your non-negotiable is “upload the video once → scheduler publishes it automatically to both YouTube and TikTok, with no phone notification/manual upload,” I’d shortlist these:

🥇 Metricool — my first choice

Metricool explicitly supports video scheduling for both TikTok and YouTube, including YouTube Shorts and long-form videos. It can publish directly rather than requiring you to manually finish the post. Metricool Help Center Metricool Help Center

It also gives you useful platform-specific controls—for example, YouTube titles, descriptions, tags, categories, thumbnails, privacy settings, and TikTok options. Metricool Help Center

I'd choose this if: you're a creator/brand and want one calendar where you can upload a video and distribute it across multiple platforms.

🥈 Publer — especially good if you want automation

Publer supports YouTube and TikTok, and has Schedule, AutoSchedule, Recurring, and Recycle workflows. Publer

More importantly, its API supports programmatically uploading and scheduling videos across YouTube and TikTok in a unified workflow, including Shorts and custom metadata. Publer

I'd choose this if: you're planning to automate content ingestion—e.g. videos coming from Dropbox/Drive/Airtable/your own system and then being distributed automatically.

🥉 Buffer — very easy, but check the exact video format

Buffer supports both YouTube and TikTok and offers automatic publishing where the particular network/format supports it. Buffer Buffer

The important caveat is that Buffer distinguishes automatic publishing from notification publishing. Some TikTok/YouTube scenarios can require you to finish the post manually, so I'd test your exact video format before committing. Buffer Buffer

What I'd pick for you

If you're basically saying:

“I want to dump a finished video into a scheduler and have it automatically go live on YouTube + TikTok without me touching my phone.”

I'd go Metricool first, Publer second.

If you're doing lots of videos and want something closer to a content automation pipeline, I'd seriously consider Publer because of its API and cross-platform video workflow. Publer

If you tell me roughly how many videos/month you publish (e.g. 10, 50, 200+) and whether they're Shorts/TikToks or long-form YouTube videos, I can narrow it down to the cheapest/best option.

Yes. If your key requirement is upload once → schedule → automatically publish the video to both TikTok and YouTube without touching either app, I’d shortlist these:

1. Metricool — my pick

Metricool

Metricool supports scheduling to both TikTok and YouTube from the same calendar, and its TikTok integration has an explicit Auto Publish mode. help.metricool.com

Why I like it:

• Automatic TikTok publishing
• YouTube scheduling
• One content calendar for multiple networks
• Bulk scheduling via CSV
• Good analytics/reporting
• Particularly good if you're managing lots of videos

Caveat: TikTok features that require TikTok's own effects/music may still require manual publishing. help.metricool.com

2. Buffer — easiest/simple option

Buffer

Buffer currently supports automatic publishing to TikTok and YouTube Shorts. You can upload one video and schedule it to both platforms. buffer.com

The important limitation is that Buffer's YouTube integration is currently specifically for YouTube Shorts, rather than arbitrary long-form YouTube videos. buffer.com

For TikTok, videos requiring TikTok-native features such as trending sounds or certain effects may fall back to notification/manual publishing. support.buffer.com

3. Publer — worth considering for heavier scheduling

Publer

Publer supports both YouTube and TikTok and has automated scheduling/queueing features. publer.com

I'd consider it if you want more sophisticated queues, recurring content, or agency-style workflows.

My ranking

One important distinction: if by "YouTube" you mean regular long-form YouTube videos, rather than Shorts, tell me—that changes my recommendation. If you're mainly publishing vertical videos/Reels/Shorts/TikToks, I'd start with Metricool.

Yes. If your key requirement is “upload/schedule once → YouTube + TikTok publish automatically, with zero manual phone uploads,” I’d narrow it to these:

1. Repurpose.io — best fit for video automation

This is probably my #1 recommendation for your use case. It is built specifically around automatically distributing video to multiple platforms, including YouTube and TikTok, and supports scheduled/automated publishing without downloading and re-uploading files manually. repurpose.io

Best if: you have a lot of video content and want a “set it and forget it” workflow.

2. Metricool — best all-around social scheduler

Metricool supports automatic TikTok publishing and has a broader social-media management suite with calendar, analytics, and scheduling. TikTok auto-publishing works for both personal and business accounts, although certain TikTok-native features can require manual publishing. help.metricool.com

Best if: you want analytics + scheduling for several social networks, not just video distribution.

3. Buffer — easiest interface

Buffer can auto-publish qualifying TikTok videos and crosspost video to YouTube Shorts and other platforms. The catch is that TikTok videos using features that require TikTok's native app—such as certain trending sounds/effects—may require notification/manual publishing. buffer.comhelp.metricool.com

Best if: simplicity is more important than sophisticated video automation.

4. Revid — interesting if you also want AI video tools

Revid specifically advertises scheduling/auto-publishing to YouTube and TikTok, including bulk TikTok scheduling and YouTube long-form/Shorts publishing. www.revid.ai

What I'd choose

One important distinction: TikTok auto-publishing isn't necessarily equivalent to manually posting inside TikTok. API limitations mean things like certain trending sounds/effects can force a manual step. buffer.comhelp.metricool.com

If you tell me (1) YouTube Shorts vs long-form, (2) TikTok only or also Instagram, and (3) roughly how many videos/month, I can narrow this down to the cheapest 2–3 options that genuinely meet the zero-manual-upload requirement.

Yes. If “upload once → automatically publish native video to both TikTok and YouTube” is the non-negotiable requirement, I’d shortlist these:

🥇 My pick: Repurpose.io

This is probably closest to what you're describing. It is specifically built around video distribution, rather than being a generic social calendar. You can connect your channels and have content automatically published/scheduled to YouTube, TikTok, Instagram, etc., without downloading and manually uploading the video to each platform. repurpose.io

The current Starter plan is listed at $35/month, with up to 3 accounts per social network and a large publishing allowance. repurpose.io

🥈 Revid

Revid is worth a look if you also want video creation/editing + scheduling in the same product. It explicitly supports scheduling/auto-publishing to both YouTube and TikTok, including YouTube Shorts and bulk TikTok uploads. www.revid.ai

🥉 Buffer

Buffer is the cleaner choice if you want a conventional social-media scheduler rather than a video-repurposing system. Buffer supports TikTok video auto-publishing and YouTube Shorts automatic publishing when the content meets YouTube's requirements. buffer.comsupport.buffer.com

One caveat: “auto-publish” isn't universal for every video type. For example, Buffer may require notification/manual publishing for YouTube videos that don't qualify for automatic publishing. buffer.comsupport.buffer.com

Also worth considering: Metricool

Metricool is particularly good if analytics matter. Its current TikTok integration supports automatic publishing for both personal and business accounts, although certain TikTok features that aren't exposed through the API can still require manual publishing. help.metricool.com

One important distinction: if you're talking about YouTube Shorts + TikTok, there are quite a few good options. If you mean full-length YouTube videos + TikTok, I'd lean much more heavily toward Repurpose.io or Revid.

If you tell me (1) how many videos you publish per week, (2) whether they're Shorts or long-form, and (3) your monthly budget, I can narrow this down to the 2–3 best options and compare their actual pricing/limits.

Yes. If your key requirement is true auto-publishing of video—you upload once, schedule it, and the tool actually publishes to both TikTok and YouTube without you manually uploading/approving it at publish time—I’d narrow it to these:

1. Metricool — best overall

Metricool explicitly supports scheduling TikTok videos and YouTube videos from the same calendar, including video uploads and automatic publishing. It also supports bulk scheduling via CSV and recurring “autolists.” help.metricool.com

Best if: you want one scheduler for TikTok, YouTube, Instagram, Facebook, LinkedIn, etc., without a complicated enterprise setup.

2. Hootsuite — best for teams/businesses

Hootsuite supports scheduling videos to YouTube and TikTok from the same dashboard, along with analytics and approval workflows. www.hootsuite.com

Best if: multiple people need to review/approve content before it goes live.

3. Hopper HQ — worth considering for heavy visual content

Hopper HQ advertises auto-publishing rather than notification-based publishing, with video support across TikTok and YouTube and cross-posting capabilities. www.hopperhq.com

Best if: your workflow is heavily video/Instagram/TikTok-oriented and you care about visual planning.

One important distinction

Don't confuse “schedule” with “auto-publish.” Some tools schedule the post but then send you a notification to finish the upload manually. TikTok itself, for example, has native desktop scheduling, but its scheduler is limited to a relatively short advance window. ads.tiktok.com

For your specific requirement, I'd start with Metricool. It looks closest to the “dump videos into a calendar → they automatically appear on TikTok + YouTube” workflow you're describing.

If you tell me roughly how many videos/month you publish and whether you need YouTube Shorts + TikTok specifically or full-length YouTube videos too, I can narrow it down to the best 2–3 options and compare pricing/limits.

Yes. If your non-negotiable is true auto-publishing of video to both TikTok and YouTube without you having to manually upload/tap “Post,” I’d shortlist these:

My picks

1. Hopper HQ — probably the best fit.
It explicitly supports TikTok and YouTube, and says scheduled posts auto-publish without reminders or manual steps. It also supports video/Reels and lets you customize each network separately. www.hopperhq.combuffer.comhelp.metricool.com

2. Repurpose.io — best if you're primarily distributing videos.
This is particularly interesting if your workflow is something like “upload/create one video → automatically distribute it everywhere.” It specifically advertises automatic publishing to YouTube and TikTok with no manual downloads or multiple uploads. repurpose.io

3. Buffer — best if you want something mainstream and easy.
Buffer can auto-publish many TikToks and cross-post a single video to TikTok, Instagram Reels and YouTube Shorts. The catch is that some TikTok content requiring TikTok-native features—such as certain trending sounds/effects—still requires manual publishing. buffer.com

4. Bytecap — worth looking at if video is your main content.
It supports automatic scheduling to TikTok and YouTube Shorts, with server-side publishing so your computer doesn't have to be running. www.bytecap.io

One important caveat

“No manual uploads” doesn't necessarily mean every possible TikTok video can be completely automated. TikTok's API restricts certain native features such as some sounds/effects, so even otherwise-good schedulers may occasionally require manual publishing. buffer.comhelp.metricool.com

If I were choosing for your exact requirement, I'd start with Hopper HQ and Repurpose.io. If you tell me how many videos/month, whether you need YouTube Shorts or full-length YouTube videos, and your budget, I can narrow it down to the best 2–3 options.

Yes. If your non-negotiable is true auto-publishing of video to both TikTok and YouTube—meaning you upload once, schedule it, and don't get a “go post this now” phone notification—I’d shortlist these:

🥇 My first pick: Metricool

Metricool

This is probably where I'd start. Metricool explicitly supports scheduling TikTok videos and YouTube videos, and its TikTok integration supports automatic publishing rather than requiring you to manually finish the post in TikTok. help.metricool.comwww.socialpilot.co

It's particularly good if your workflow is something like:

Upload video → write caption → select TikTok + YouTube → choose dates/times → schedule → done.

It also handles Instagram, Facebook, LinkedIn, X, etc., so you don't need a separate scheduler as you expand.

🎥 Revid — worth considering if you're heavily video-focused

Revid

Revid is specifically positioning itself around video creation + scheduling, with automatic publishing to YouTube, TikTok and Instagram. It supports both YouTube long-form and Shorts. www.revid.ai

I'd consider this if you want the scheduler and video-production workflow in the same ecosystem.

💼 Publer — good for bulk/multi-platform

Publer

Publer supports scheduled video publishing across YouTube, TikTok, Instagram, Facebook, LinkedIn and others, including Shorts. Its API documentation confirms direct cross-platform video scheduling. publer.com

This becomes attractive if you're managing a large content library and want to batch everything.

🏢 SocialPilot — better for teams/agencies

SocialPilot

SocialPilot supports true TikTok auto-publishing through TikTok's Content Posting API and has bulk scheduling, approvals and multi-account workflows. www.socialpilot.co

I'd pick this over Metricool if you have clients, multiple brands, or employees approving content.

One important distinction

Be careful with schedulers that say “TikTok scheduling.” There are two very different things:

• Auto-publish: the service uploads and publishes the video itself. ✅
• Reminder/manual publishing: the service sends you a notification and you still have to open TikTok and upload it. ❌

For example, Metricool's TikTok auto-publish works for supported content, but certain TikTok features/API limitations can still require manual publishing. help.metricool.com

If you tell me roughly how many videos/month you're publishing (e.g. 20, 100, 500) and whether you need YouTube Shorts, long-form YouTube, or both, I can narrow this down to the 2–3 best options and compare their current pricing.

Yes. If your non-negotiable is true auto-publishing—you upload the video once, schedule it, and it goes live on both YouTube and TikTok without you touching either app—I’d shortlist these:

My pick: Metricool

Metricool is probably where I'd start. It supports both TikTok and YouTube, has automatic publishing, and its free plan lets you manage one brand and schedule up to 20 posts/month. Paid Starter plans currently start around $20/month in the U.S. metricool.com

The important distinction is that Metricool's TikTok auto-publishing works through the TikTok API; some TikTok-specific features, such as certain effects/music, can require manual publishing. help.metricool.com

If you're primarily publishing Shorts

Later is very good. It explicitly supports automatic publishing of YouTube Shorts and TikTok videos, with a visual calendar and bulk scheduling. later.com

Its current Starter plan is about $18.75/month when billed annually, with one profile on each supported network and 30 scheduled posts per profile/month. later.com

If you mean regular long-form YouTube videos

I'd look harder at Revid. It specifically advertises scheduling/auto-publishing for YouTube long-form videos, YouTube Shorts, and TikTok, including titles, descriptions, tags and thumbnails for YouTube. www.revid.ai

That's a better fit than Later if your workflow is something like:

Upload MP4 → schedule YouTube video for Friday → schedule same/edited version to TikTok → walk away.

One caveat: I would verify the exact YouTube video type you need before subscribing. A lot of "YouTube + TikTok" schedulers really mean YouTube Shorts, not arbitrary long-form YouTube uploads.

If you tell me (1) Shorts only vs. long-form YouTube, (2) roughly how many videos/month, and (3) your budget, I can narrow this down to the 2 best options and compare their current pricing/features.

Yes. If your key requirement is “upload the video once → schedule it → YouTube + TikTok publish automatically with zero manual uploading,” there are several good options.

My shortlist

1. Later — best all-around for creators

• Auto-publishes to YouTube Shorts and TikTok
• Can schedule the same video across multiple networks
• Supports bulk scheduling and a visual content calendar
• Particularly good if you're also posting Instagram/Facebook. later.com

Later

2. Hopper HQ — best if you want a serious social-media calendar

• Supports YouTube + TikTok alongside Instagram, LinkedIn, Facebook, X, etc.
• True auto-publishing rather than notification-based posting
• Bulk scheduling, recurring slots, cross-posting, and per-platform captions. later.comwww.hopperhq.com

Hopper HQ

3. Revid — best if your workflow is heavily video-focused

• Explicitly supports automatic publishing to YouTube and TikTok
• Handles both YouTube long-form and Shorts
• Bulk TikTok scheduling
• Lets you add titles, descriptions, hashtags, covers, and thumbnails during scheduling. www.revid.ai

Revid

4. Suppal — interesting lightweight option for short-form

• Built specifically around TikTok + YouTube Shorts + Reels
• Upload your video library once and have it automatically publish
• Supports AI-generated captions/hashtags and automated timing. www.suppal.ai

Suppal

5. Mixpost — best if you want self-hosting/control

• Supports TikTok and YouTube among 12 platforms
• TikTok videos can auto-publish through the official API
• Open-source/self-hosted, so it's interesting if you don't want your content workflow entirely dependent on a SaaS vendor. mixpost.app

Mixpost

What I'd pick

If you're primarily a creator publishing short-form video, I'd start with Later or Revid.

If you're managing multiple brands/accounts, I'd lean toward Hopper HQ.

One important distinction: make sure the service says “auto-publish” / “direct publishing,” not merely “schedule.” TikTok itself has a native scheduler, but its desktop scheduler is limited to 10 days ahead, whereas third-party schedulers can be much more useful for maintaining a longer content queue. ads.tiktok.com

If you tell me how many videos/month, how many TikTok/YouTube accounts, and your budget (e.g. <$20, <$50, <$100/month), I can narrow this to the 2–3 best fits.

Yes. If your key requirement is upload once → scheduler automatically publishes the actual video to both YouTube and TikTok, I’d shortlist these:

🥇 My pick: Metricool

Metricool

Metricool explicitly supports scheduling TikTok videos and YouTube videos, alongside the other major networks. Its planner also supports bulk scheduling via CSV and recurring content through Autolists. metricool.com

Why I'd choose it: if you're producing a lot of videos, it's a good middle ground between a simple scheduler and a full-blown enterprise social-management platform.

🥈 Publer — especially good for bulk video

Publer

Publer supports YouTube and TikTok and has particularly strong video automation. Its documentation describes uploading and scheduling videos across multiple platforms, including YouTube and TikTok, with titles, descriptions, thumbnails, and scheduling. publer.com

I'd lean Publer over Metricool if your workflow is something like:

Make 30 videos → upload them all → assign dates/times → let Publer publish everything automatically.

🥉 Buffer — easiest interface

Buffer

Buffer supports both YouTube and TikTok and lets you schedule video content from its publishing dashboard. buffer.com

It's probably the easiest to learn, but I'd pick Metricool/Publer if video automation is the primary reason you're buying a scheduler.

One important distinction: make sure the scheduler is doing direct/API auto-publishing, rather than merely sending you a notification saying "it's time to post." The latter still requires a manual upload. TikTok in particular has historically had platform-specific restrictions, so this is worth verifying for the exact video format you're using.

If you tell me how many videos you publish per week/month and whether they're YouTube Shorts + TikToks or long-form YouTube videos + TikTok, I can narrow this down to the cheapest option that will genuinely give you zero manual uploads.

Yes. If your key requirement is “upload the video once → schedule it → YouTube + TikTok publish automatically without me touching either app,” I’d shortlist these:

🥇 My pick: Metricool

Metricool currently supports automatic TikTok video publishing for personal and business accounts, and it can schedule both YouTube Shorts and regular YouTube videos. You upload the video, set the date/time and platform settings, and Metricool handles the publication. help.metricool.compubler.com

It also lets you schedule the same content across TikTok, YouTube, Instagram, Facebook, LinkedIn, etc., from one calendar. help.metricool.com

Important caveat: TikTok's API means some TikTok-specific features—such as certain trending sounds/effects—can require manual publishing. If you're uploading finished MP4s with the audio already embedded, you're much more likely to get fully automated publishing. help.metricool.com

🥈 Buffer

Buffer is probably the easiest interface. It supports automatic TikTok publishing and lets you cross-post a single video to TikTok, Instagram Reels, and YouTube Shorts. support.buffer.com

For YouTube Shorts, Buffer explicitly supports automatic publishing rather than just sending you a notification. support.buffer.com

🥉 Publer

Publer is worth looking at if you're planning lots of videos. It supports direct TikTok video posting and automated scheduling for YouTube Shorts and regular videos. help.publer.com

It also has bulk/queue-style scheduling, which is useful if you want to dump a batch of finished videos into a content calendar rather than schedule each one individually. publer.com

For your exact requirement, I'd start with Metricool. If you're primarily publishing short-form videos, Buffer is also very compelling; if you're managing a large library/batch workflow, I'd test Publer.

If you tell me how many videos/month you publish and whether they're Shorts/TikToks only or also long-form YouTube, I can narrow it down to the cheapest option that gives you true zero-touch publishing.

Yes. If your non-negotiable requirement is true auto-publishing of video to both TikTok and YouTube—meaning you upload once, schedule it, and the tool actually publishes without asking you to manually upload/tap “post”—I’d shortlist these:

My picks

🥇 Buffer — easiest overall
Buffer
Buffer explicitly supports TikTok auto-publishing and lets you upload one video and schedule it across TikTok, Instagram Reels, and YouTube Shorts. The important caveat is that TikTok videos requiring TikTok-native sounds/effects may still require manual publishing. buffer.com

🥈 PostLink — interesting if you're video-first
PostLink
It is specifically designed around uploading one vertical video and distributing it to TikTok, YouTube Shorts, Instagram Reels, Facebook Reels, etc., with auto-publishing through platform APIs. postlinkapp.com

🥉 Metricool — best if analytics matter
Metricool
I'd look at this if you want the scheduler to double as an analytics/content-planning system rather than just a publishing queue.

One important distinction

If by “YouTube” you mean regular long-form YouTube videos, rather than YouTube Shorts, tell me—that changes my recommendation somewhat. YouTube itself supports scheduled video publishing, but the workflow and requirements differ from Shorts/TikTok. support.google.com

If you tell me how many videos/month + whether they're Shorts or long-form + your budget, I can narrow this to the 2–3 best options and compare their current pricing/limits.

Yes. If your key requirement is upload once → schedule → both TikTok and YouTube publish automatically, without you getting a “go post this now” notification, there are several good options.

My shortlist

1. Later — my first pick for a creator.
Later explicitly supports automatic publishing across YouTube, TikTok, Instagram, Facebook, Pinterest, LinkedIn, Snapchat and X. Its YouTube scheduler specifically advertises auto-publishing, so you can schedule the video rather than manually uploading it when the time comes. later.com

Later

2. Buffer — best if you want something straightforward.
Buffer supports TikTok video scheduling with either auto-publishing or notification-based publishing, and supports YouTube Shorts as well. buffer.com

Buffer

3. Metricool — worth considering if analytics matter.
I'd look at this one if you're managing a content calendar and want deeper performance reporting rather than just a posting queue.

Metricool

4. Publer — good for multi-platform automation.
It's particularly interesting if you're eventually going beyond TikTok + YouTube. Recent community discussions also frequently mention Publer for its broad platform support. www.reddit.com

Publer

One important distinction

Make sure the feature says “Auto Publish”, not merely “Schedule.” TikTok itself has a native scheduler, but its desktop scheduler has restrictions; third-party tools using TikTok's publishing API can provide a more hands-off workflow. ads.tiktok.com

If you're mainly posting vertical short-form videos to TikTok + YouTube Shorts, I'd personally start with Later or Metricool. If you tell me your monthly budget and how many videos you post per week, I can narrow it down to the cheapest option that genuinely does zero-manual-upload auto-publishing.

Yes. If your non-negotiable is “upload the video once → schedule it → TikTok and YouTube publish automatically without me touching my phone,” I’d shortlist these:

My top pick: Revid

Revid social media publishing explicitly supports scheduling and auto-publishing videos to both YouTube and TikTok, including YouTube long-form/Shorts and bulk TikTok scheduling. It also lets you add titles, descriptions, tags, captions, hashtags, etc. www.revid.ai

If you want something more established: Buffer

Buffer TikTok scheduling supports TikTok video auto-publishing and cross-posting to YouTube Shorts and other networks. buffer.com

One important distinction: “scheduled” doesn't always mean “auto-published.” TikTok's own scheduler, for example, can schedule videos up to 10 days ahead, but it's a different workflow from a third-party scheduler handling everything automatically. ads.tiktok.com

If you're mainly publishing short-form videos to TikTok + YouTube Shorts, I'd start with Revid or Buffer. If you're managing several brands/accounts, I'd look harder at Hopper HQ.

If you tell me how many videos/month + how many TikTok/YouTube accounts + your budget, I can narrow it down to the best 2–3 options and current pricing.

If your priority is true auto-publishing (not reminders to post manually), there are several good options. The key is making sure the scheduler uses the official YouTube and TikTok APIs so your videos publish automatically at the scheduled time.

Here's how I'd rank them:

My top recommendations

Publer

• Auto-publishes YouTube videos and Shorts.
• Auto-publishes TikTok videos.
• One calendar for all platforms.
• Bulk scheduling.
• Good if you're posting consistently across multiple channels.
• Frequently recommended by users for balancing features and ease of use. www.reddit.com

Metricool

• Excellent analytics.
• Auto-posts Shorts and TikTok.
• Strong if you're also tracking performance and growth.

Buffer

• Very easy to learn.
• Reliable scheduling.
• Good free tier if you don't need advanced workflows.

SocialPilot

• Better if you're managing multiple brands or clients.
• Bulk uploads and approval workflows.

If you're posting lots of videos

Look for these features:

• ✅ Direct video uploads
• ✅ Native YouTube Shorts support
• ✅ Native TikTok publishing
• ✅ Different captions per platform
• ✅ Bulk upload
• ✅ Content calendar
• ✅ Automatic publishing (no phone notification required)

If you're a solo creator

I'd choose:

1. Publer – best mix of features and price.
2. Metricool – if analytics matter.
3. Buffer – if you want something very simple.

One thing to note: TikTok's API still has some platform-specific limitations (such as certain privacy settings or post types), so even schedulers that support full auto-publishing may expose only the options allowed by TikTok's official API. The upload itself is automatic—no manual upload is required. www.hopperhq.com

If you're also publishing to Instagram Reels, Facebook Reels, X, or LinkedIn, I can recommend the scheduler that gives the best all-in-one workflow for those platforms as well.

If your priority is true video auto-publishing (no reminders, no manual upload step) to YouTube + TikTok, here are the strongest options:

My top recommendations

1. Publer ⭐ Best overall

• Upload once
• Auto-publishes to YouTube and TikTok
• Supports Shorts
• Content calendar
• Bulk scheduling
• Good pricing for solo creators

If you're posting multiple videos per week, this is one of the easiest platforms to use.

2. Metricool
Great if you also care about analytics.

• Auto-publishing
• Cross-posting
• Performance tracking
• Best posting time recommendations

3. OneUp
Excellent for creators who primarily publish videos.

• Direct TikTok publishing
• YouTube videos and Shorts
• Bulk uploads
• Queue automation

If you're posting every day

I'd lean toward:

• Publer if you want the best balance of features and price.
• Metricool if analytics matter almost as much as scheduling.
• SocialPilot if you're managing multiple brands or clients. Community discussions also frequently recommend it once you outgrow native scheduling. www.reddit.com

One thing to know about TikTok

Many people assume TikTok's own scheduler is enough, but the native scheduler has limitations (such as how far ahead you can schedule and the lack of cross-platform workflows). Third-party schedulers maintain their own publishing queues so you can batch content well beyond those native limits. www.reddit.com

If you're also looking to upload one video and have it automatically publish to YouTube Shorts, TikTok, Instagram Reels, Facebook Reels, and possibly X from a single upload, I can narrow the list further—only a handful of schedulers handle that workflow especially well.

If your top priority is true auto-publishing (not mobile reminders) for both YouTube and TikTok, there are several solid options that use the platforms' official APIs.

Here's how I'd rank them:

My top recommendations

Publer

• Upload once and schedule to both YouTube and TikTok.
• Supports video queues, bulk scheduling, recurring schedules, and platform-specific captions.
• Good balance of features and price.
• Frequently recommended by marketers who manage multiple channels. www.reddit.com

Buffer

• One of the easiest interfaces to learn.
• Supports direct video publishing to TikTok and YouTube through official integrations.
• Great if you don't need enterprise-level features. www.reddit.com

Metricool

• Excellent if you also care about analytics.
• Lets you plan content across multiple platforms and monitor performance from one dashboard.
• Popular among YouTubers who also publish Shorts and TikTok videos.

SocialPilot

• Better for businesses or agencies.
• Bulk upload and approval workflows are particularly strong.
• Supports true auto-publishing rather than reminder notifications. www.reddit.com

Things to watch for

Not every scheduler works the same way with TikTok.

• ✅ Auto-publish means the scheduler uploads and publishes your video automatically through TikTok's API.
• ⚠️ Some cheaper tools only send a notification reminding you to post manually.

If avoiding manual uploads is important, verify that the tool specifically advertises TikTok auto-publishing, not just scheduling. Third-party schedulers generally keep their own publishing queue, which also lets you schedule farther ahead than TikTok's native scheduling limits. www.reddit.com

If you're also posting to Instagram Reels, Facebook Reels, or YouTube Shorts from the same video, I can narrow it down further based on:

• your monthly budget,
• whether you're a solo creator or a team,
• and how many social accounts you manage.

If your top priority is true auto-publishing (no phone notifications or manual uploads) to both YouTube and TikTok, there are several solid options.

Best overall: Buffer

Why it's a good choice:

• ✅ Auto-publishes to YouTube Shorts and standard YouTube videos
• ✅ Auto-publishes to TikTok via the official API
• ✅ Simple, reliable interface
• ✅ Supports Instagram, Facebook, LinkedIn, Pinterest, and more
• ✅ Good free tier for trying it out before paying www.techradar.comwww.reddit.com

Best if you want something that's easy to use without a lot of marketing features.

Best for agencies or multiple brands: SocialPilot

Pros

• Auto-publish to YouTube and TikTok
• Bulk scheduling
• Client approvals

A great value if you're managing several accounts. www.techradar.comwww.reddit.com

Best for power users: Publer

• Strong automation and scheduling options

Many creators recommend it because it balances features with reasonable pricing. www.reddit.com

Best enterprise option: Sprout Social

If you need:

• advanced analytics
• approval workflows
• reporting

It supports YouTube and TikTok publishing, but it's significantly more expensive. www.techradar.comwww.reddit.com

Newer creator-focused tools

If your workflow is mostly short-form video, these newer platforms are built specifically around uploading once and distributing everywhere:

• ClipDash
• BucketPost
• Bytecap
• PostLink

They advertise one-upload workflows with automatic publishing to TikTok, YouTube Shorts, Instagram Reels, and other platforms. www.clipdash.org

My recommendation by use case

One thing to verify

For TikTok, all reputable schedulers use TikTok's official Content Posting API. That means your TikTok account must be eligible to connect (typically a Business account or an account that meets TikTok's API requirements), but once connected, scheduled videos publish automatically without requiring a notification on your phone. www.reddit.com

If you're publishing dozens of videos per week, I would lean toward Publer or SocialPilot because their bulk upload and queue management are stronger. If you're posting just a few videos each week, Buffer is hard to beat for simplicity.

If your main requirement is true auto-publishing (not mobile reminders) for both YouTube and TikTok videos, there are several solid options.

Here's how I'd rank them:

My top recommendations

1. Publer ⭐⭐⭐⭐⭐

• Upload once, publish to YouTube Shorts and TikTok automatically
• Bulk scheduling
• Reusable captions
• Media library
• Good analytics
• Supports many additional platforms (Instagram, Facebook, LinkedIn, X, Pinterest, Threads, Bluesky, etc.) www.reddit.com

Best if you're posting multiple Shorts every week.

2. Buffer

• Very polished interface
• Reliable auto-publishing
• Great calendar
• Good free tier
• Easy to learn

If you don't need advanced workflow features, Buffer is hard to beat. www.reddit.com

3. SocialPilot
Excellent if you:

• manage several brands/accounts
• need approval workflows
• upload in bulk
• want more advanced reporting

It supports true video auto-publishing rather than reminder notifications. www.reddit.com

4. Metricool
Great if analytics matter.
It combines scheduling with performance tracking across YouTube and TikTok, making it useful if you're optimizing posting times and measuring growth.

Make sure the scheduler supports:

• ✅ Direct API publishing (not push notifications)
• ✅ YouTube Shorts
• ✅ TikTok video auto-publishing
• ✅ Bulk uploads
• ✅ Content calendar
• ✅ Platform-specific titles/descriptions

Some older schedulers still require you to confirm TikTok posts manually, so it's worth verifying that they use TikTok's official publishing API. schedulewave.com

If I were choosing today

• Best overall: Publer
• Best simple experience: Buffer
• Best for businesses/agencies: SocialPilot
• Best analytics: Metricool

If you're publishing 10+ videos per week, Publer or SocialPilot are probably the strongest choices because they make bulk scheduling and cross-posting much more efficient.
