Titled posts to the minute
Text, link or image posts to the community you name at the time you choose.
On the roadmap
Lemmy is on ClipSpeed's roadmap after the next rail. The badge says where it stands.
Clips by link
Share a hosted clip as a link post with the hook as the title.
Community-aware pacing
Conservative caps so a scheduled account does not read as spam.
Plan, schedule Lemmy community posts, and grow, from one calendar
A Lemmy scheduler should do more than post on time. ClipSpeed pairs the calendar with the clipping engine and the image and video models, so the content and the schedule come from the same place, and with booking rules that keep the account healthy.
The weekly write-up
An agent turns your notes into a titled Markdown post and books it for Monday.
Clips as link posts
The best stream moment, shared where the community is.
From any agent
"Post this to the community at 10am with a clear title."
Generated diagrams
Make the diagram in the conversation and post it with a title.
Schedule Lemmy from any AI agent
Every agent below can post to communities on Lemmy through ClipSpeed's MCP server: one URL, OAuth sign-in, the same rules. Each link is a full guide with the Lemmy settings reference and prompts.

What Postiz-style schedulers cannot do
Cut the clips first
Your agent 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. Your agent picks by score, writes the caption from the transcript, and books the clips on Lemmy. 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. Your agent 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 Lemmy. The caption, the time and the file are approved together.The other half nobody else has
Generate the image or video, then post it
A product shot for Instagram, a 16:9 announcement graphic for X, a six-second opener before a clip: your agent can make an image or 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.
- Images post as JPG, PNG or WebP up to 25 MB; video posts as MP4, MOV or WebM up to 1 GB.
How Lemmy booking works
The rules are the product's trust. They run on the server, so the app, the API and every AI agent book the same way.
- Exact or refused. A time you name is booked to the minute or refused with the reason and the next open slot. ClipSpeed never moves a booked post without asking.
- As soon as possible is placed and said. Leave the time out and the reply tells you exactly where the post landed.
- Preview books nothing.
preview: trueruns the whole booking, including caps, spacing and slot choice, and writes nothing. It is how a week gets planned before it is booked. - Limits are refused at booking, never trimmed at send time. The reply carries the real count so the fix is one edit.
- Pacing protects the account. Planned: Text posts on Lemmy are at least 60 minutes apart, up to 5 a day.
- One piece of content goes to one platform once. The same text or the same file to the same platform is recognised as a duplicate and refused.
- Cancel is undoable for 72 hours in the ClipSpeed app. Copy can be edited while a post is still scheduled; the time cannot, by design.
- A title is required (200 characters). The body is Markdown up to 10,000.
- Each community has its own rules on self-promotion; a scheduler does not change that.
- Lemmy is on ClipSpeed's roadmap, not the next rail. Bookings are refused plainly until it posts.
- You connect your own instance, not Lemmy in general.
Take the hassle out of Lemmy
Plan a month of community posts in one conversation, approve the plan, and let ClipSpeed publish at the exact minute, leaving you more time to make the next one.
Lemmy scheduling: frequently asked questions
How do I set up automatic posting to Lemmy with ClipSpeed?
Connect your Lemmy account to ClipSpeed once through Lemmy's own sign-in (ClipSpeed never sees the password), then book a post from the calendar in the app or ask an AI agent such as Claude or ChatGPT. ClipSpeed publishes at the booked minute through Lemmy's official API. Lemmy is on the roadmap; the badge on this page changes the day it posts.
How do I schedule many Lemmy posts at once?
Ask an agent to plan the batch and preview it: "plan one post a day at 5pm next week, show me first" returns every slot and the day's remaining cap with nothing booked. Approve and it books all of them in one reply. Planned: Text posts on Lemmy are at least 60 minutes apart, up to 5 a day. A taken slot is refused with the next open one, never moved quietly.
Does ClipSpeed post to Lemmy today?
Not yet. Lemmy is on the roadmap after the next rail. The badge on this page changes when it posts.
Which Lemmy instances will work?
Any instance running the standard Lemmy API; you connect your own.
What are the limits?
A title up to 200 characters is required; the body is Markdown up to 10,000.
Will I be able to post to several Lemmy communities, with text, links and images?
When Lemmy goes live on ClipSpeed it will post text, link and image posts to the community you pick for each post; booking one post to several communities at once is not available yet.
Does ClipSpeed have a Lemmy content calendar?
When Lemmy goes live on ClipSpeed, its posts will sit on the same week and month calendar as YouTube, TikTok, Instagram, X and LinkedIn, with the same drag-to-reschedule. Lemmy is not bookable yet, so nothing for it appears on the calendar until its badge changes.
Can I cross-post to Lemmy and other networks from one request?
When Lemmy goes live on ClipSpeed, one request can book the same clip, image or text to several connected platforms; each keeps its own time slot, its own text limit and its own daily cap. Ask an agent to write a different caption for each platform and it books them as separate posts. Until then the same request works for YouTube, TikTok, Instagram, X (Twitter) and LinkedIn.
Can ClipSpeed automatically repost my best Lemmy content?
Not yet. ClipSpeed does not republish posts on a timer. It also posts one piece of content to one platform once, so a rerun means a fresh clip cut from the same video, or a new image, booked like any other post inside your daily cap.
Can I set recurring Lemmy posting slots?
Not as fixed weekly slots yet. When Lemmy goes live on ClipSpeed, Fill My Calendar and agent plans will work for it the way they do for the platforms posting today.
Can my team collaborate on Lemmy posts in ClipSpeed?
Not yet. A ClipSpeed account is one person's workspace: there are no team seats, approval steps or shared drafts, and each platform connects one account. Agencies run one ClipSpeed account per brand today.
Is there a free Lemmy scheduler?
ClipSpeed has no free plan. The $1 trial starts the same account you keep, and scheduling is included on every paid plan at no extra cost, alongside clipping and AI image and video generation on one credits wallet.
What Lemmy analytics does ClipSpeed show?
Views, likes, comments and shares per post where Lemmy provides them, with the time they were last read, in the calendar and through the agent tools. ClipSpeed says plainly when numbers are not available for a post or a platform rather than showing a zero. ClipSpeed does not shorten links or count link clicks yet.
Can I schedule Lemmy posts from Claude or another AI assistant?
Yes. ClipSpeed runs an MCP server at https://api.clipspeed.ai/mcp, so Claude, ChatGPT, Claude Code, Codex, Cursor, Windsurf and any other MCP client can sign in with OAuth and post to communities on Lemmy on your behalf. The assistant drafts within Lemmy's limits, picks the slot, previews the plan and books on your yes. It can also cut the clips and generate the images in the same conversation. See the Lemmy guides for each agent below.
Is there an API for Lemmy scheduling?
Yes. The same booking service behind the app and the MCP server is available over the ClipSpeed REST API with an API key, so your own backend or an automation tool can schedule a Lemmy post or upload a video programmatically. The rules are identical: exact or refused, preview mode, per-platform limits. The developer pages under /mcp/ document the keys and the tool contract. Webhooks fire when clips finish (a signed clips.completed event); a webhook when a post publishes is not available yet.
Can ClipSpeed make the Lemmy content, not just post it?
That is the difference. Paste a long video or a live stream and ClipSpeed cuts captioned 9:16 clips with a viral score, which post to Lemmy as native video. Generate an image or a short video with ClipSpeed's models and post the result. One conversation, one calendar.
