- Connect and approve the ClipSpeed sign-in.
- Start a Cowork session, give it access to the folder with your recordings or drafts, and enable the ClipSpeed connector.

What can Claude Cowork do on YouTube?
On YouTube, Claude Cowork can upload Shorts and full videos with a title, description, hashtags and a privacy setting. Every booking runs through the same rules as the ClipSpeed app.
Video posts
YouTube takes video through ClipSpeed. Video: MP4, MOV or WebM up to 1 GB by public link, or a finished ClipSpeed clip by clip_id.
5,000 characters, checked at booking
YouTube's own arithmetic. Too long is refused with the real count, never trimmed at send time. Titles are required and cap at 100.
Exact time or refused
Name the minute and Claude Cowork books it, or you are told why not and offered the next open slot. A booked YouTube post is never moved behind your back.
Preview before anything posts
preview: true runs the whole booking and writes nothing. Claude Cowork shows the plan, with each slot and the day's remaining cap, and books only on your yes.
Clips cut in the same chat
Submit a video or stream link, get captioned 9:16 clips with a viral score, and post the best as native video on YouTube. No download, no re-upload.
Pacing and numbers
Video on YouTube is at least 4 hours apart, up to 4 a day under your plan. After a post goes out, Claude Cowork can read back views and engagement where YouTube provides them.
How does Claude Cowork post to YouTube through ClipSpeed?
You describe what you want in plain language and Claude Cowork makes the ClipSpeed calls. A typical conversation has three beats.
Find your YouTube channel
Ask Claude Cowork whether YouTube is connected. It calls list_channels and reads platform_settings, so it also knows what YouTube accepts and the limits before you write a word.
Compose within the rules
Describe the post. Claude Cowork drafts within YouTube's limits; mention a clip or a file and it attaches it.
Schedule or publish
Name a time, or say now. The slot is booked exactly or refused with the next open one, and the reply carries the id you can cancel or edit by.
YouTube settings reference
These are the schedule_post fields that apply to YouTube. Mention any of them in plain language and Claude Cowork sets them; the server checks them at booking.
| Field | Type | Required | What it does on YouTube |
|---|---|---|---|
platforms | string[] | Yes | Include "youtube". Up to ten platforms per call; each books its own slot. |
title | string | Yes | The video title. YouTube requires one; up to 100 characters. |
text | string | No | The description, up to 5,000 characters. Links stay clickable. |
hashtags | string[] | No | Appended to the description; the first three show above the title on YouTube. They count toward the 5,000. |
privacy_status | public | unlisted | private | No | Defaults to public. Ask for unlisted when you want to review the upload on YouTube before anyone sees it. |
clip_id or media_url | string | One of the two | A finished ClipSpeed clip from check_clips, or a public https link to an MP4, MOV or WebM up to 1 GB. |
scheduled_at | ISO 8601 | No | Booked exactly or refused with the next open slot. Omit it to upload as soon as a slot is free. |
preview | boolean | No | true books nothing and returns the exact slot each upload would get. |

YouTube limits and gotchas to know
YouTube enforces a few rules that Claude Cowork and ClipSpeed respect automatically, but knowing them helps you phrase requests.
- A title is required and capped at 100 characters. Ask the agent to write the title from the clip's hook line; the booking is refused, not trimmed, if it runs long.
- YouTube takes video only. A text-only or image request to YouTube is refused at booking with the message "YouTube takes video posts, not text".
- privacy_status defaults to public. Say "unlisted" or "private" in the prompt when you want to check the upload on YouTube first.
- Uploads are spaced four hours apart on the same channel and capped at your plan's daily number. A second upload inside that window is refused with the next open slot, never silently moved.
- Shorts are detected by YouTube from a vertical 9:16 frame under three minutes. ClipSpeed clips already come out 9:16; a 16:9 source uploads as a standard video.
| Rule | YouTube |
|---|---|
| Accepts | Video |
| Text limit | 5,000 characters |
| Title | 100 characters, required |
| Links in the caption | Kept |
| Pacing | Video on YouTube is at least 4 hours apart, up to 4 a day under your plan. |
| Formats | Video: MP4, MOV or WebM up to 1 GB by public link, or a finished ClipSpeed clip by clip_id. Aspect: 9:16 vertical for Shorts, 16:9 for standard uploads |

What Postiz-style schedulers cannot do
Cut the clips first
Claude Cowork does not need finished video to start. Hand it a YouTube link, a podcast, a stream VOD or a local export. ClipSpeed finds the moments, cuts them to 9:16 with word-by-word captions, scores each one 0 to 100 for shareability, and returns them in the same conversation. Claude Cowork picks by score, writes the caption from the transcript, and books the clips on YouTube. Three tool calls, one approval, no download and no re-upload.
- Clips arrive with a title written from the hook, a transcript and a viral score, so the agent can choose and caption without watching the footage.
- Live streams can be clipped while they are still on air; the agent books the highlights for the next morning before the stream ends.
- Every clip is already hosted, so
schedule_posttakes its id directly. Nothing moves through your laptop.
submit_to_clipspeedPaste the link. ClipSpeed starts the job and returns a project id.check_clipsPoll with the project id. Back come the finished 9:16 clips with titles, transcripts, viral scores and preview links.schedule_postPass the clip id, the platforms, a caption and a time. Claude Cowork shows the plan with preview: true, you say yes, it books.generate_image or generate_videoDescribe the shot. ClipSpeed runs it on the model that fits (Seedance, Kling, Veo, Nano Banana Pro, GPT Image and others) and quotes the credits first.wait_for_generationReturns the hosted result link and a preview the agent can show you.schedule_post with media_urlThe result link goes straight into the booking on YouTube. The caption, the time and the file are approved together.The other half nobody else has
Generate the video, then post it
A product shot for Instagram, a 16:9 announcement graphic for X, a six-second opener before a clip: Claude Cowork can make a short video with ClipSpeed's image and video models and book the result in the same reply. There is no separate design tool, no export, no upload page. The generated file is hosted, so media_url is the only thing the booking needs.
- The price in credits is quoted before anything renders, within the per-generation and daily caps you set in Settings.
- Results are previewed in the conversation, so you approve the picture and the post at once.
- video posts as MP4, MOV or WebM up to 1 GB.

What can Claude Cowork post to YouTube through ClipSpeed?
Upload Shorts and full videos with a title, description, hashtags and a privacy setting. YouTube takes video posts; a text-only request is refused with a message naming what it accepts. Text is limited to 5,000 characters. A title is required and is capped at 100 characters.
Which YouTube settings can Claude Cowork control?
The fields in the settings reference above: title, text, hashtags, privacy_status, clip_id or media_url, scheduled_at, preview. Mention any of them in plain language ("unlisted", "tomorrow at 9", "preview first") and Claude Cowork sets the matching field before it books.
Do I need a YouTube API key or developer account?
No. You connect YouTube to ClipSpeed once through YouTube's own sign-in, and Claude Cowork talks to ClipSpeed over OAuth. No YouTube developer key, bearer token or password is pasted anywhere.
How many YouTube posts a day can Claude Cowork schedule?
Video on YouTube is at least 4 hours apart, up to 4 a day under your plan. When a time is taken, the booking is refused with the next open slot rather than moved. Ask for preview to see a day's plan and the remaining cap before anything is booked.
Can posts go out to YouTube while I am away?
Yes. Once booked, ClipSpeed publishes at the scheduled minute whether or not Claude Cowork is open. For unattended runs that decide what to post, use a headless agent such as Claude Code or Codex with the same account.
Is posting to YouTube from Claude Cowork different from Claude Code?
The booking is identical: the same rules, the same calendar, the same refusals. What differs is where you work. Claude Cowork: claude desktop (mac and windows). Claude Code: terminal, repo, headless, ci.
