The right subreddit, the right flair
Titled posts to the community you name, with a valid flair, at the minute you choose.
On the roadmap
Reddit is on ClipSpeed's roadmap after the next rail. The badge says where it stands.
Clips as video posts
Captioned clips posted natively with the hook as the title.
Conservative pacing
Five text posts a day an hour apart so an account never reads as spam.
Plan, schedule Reddit posts across subreddits, and grow, from one calendar
A Reddit 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.
Launch day across subreddits
An agent drafts a post per community with the right flair and spaces them out.
Stream moments
The best clip, posted as native video where the community is.
From any agent
"Check the flairs in r/SideProject, pick Showcase, post the write-up at 10am."
Generated images
Make the diagram in the conversation and post it with a title.
Schedule Reddit from any AI agent
Every agent below can post to subreddits on Reddit through ClipSpeed's MCP server: one URL, OAuth sign-in, the same rules. Each link is a full guide with the Reddit 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 Reddit. 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 Reddit. 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 Reddit 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 Reddit are at least 60 minutes apart, up to 5 a day.
- Pacing protects the account. Video on Reddit is at least 4 hours apart, up to 3 a day under your plan.
- 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 up to 300 characters is required. Text bodies allow 40,000 characters of Markdown.
- Many subreddits require a flair; the planned tool lists the flairs so the agent picks a valid one.
- Subreddit rules on self-promotion apply; a scheduler does not change them, and pacing is conservative on purpose.
- Reddit is on ClipSpeed's roadmap, not the next rail. Bookings are refused plainly until it posts.
Take the hassle out of Reddit
Plan a month of posts across subreddits in one conversation, approve the plan, and let ClipSpeed publish at the exact minute, leaving you more time to make the next one.
Reddit scheduling: frequently asked questions
How do I set up automatic posting to Reddit with ClipSpeed?
Connect your Reddit account to ClipSpeed once through Reddit'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 Reddit's official API. Reddit is on the roadmap; the badge on this page changes the day it posts.
How do I schedule many Reddit 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 Reddit are at least 60 minutes apart, up to 5 a day. Video on Reddit is at least 4 hours apart, up to 3 a day under your plan. A taken slot is refused with the next open one, never moved quietly.
Does ClipSpeed post to Reddit today?
Not yet. Reddit is on the roadmap after the next rail, and its release depends on Reddit's API terms for third-party posting. The badge on this page changes when it posts.
Will it handle flairs?
Yes; the planned tool lists a subreddit's flairs so the agent can pick a valid one, because many subreddits require one.
What are the limits?
A title up to 300 characters is required; a text body up to 40,000 characters of Markdown.
Will I be able to post to several subreddits at the same time?
Not yet. Subreddits have their own rules and spam filters, so when Reddit goes live each post will go to one subreddit you pick, with its flair.
Is ClipSpeed a good Reddit scheduler for marketers?
Not yet: Reddit is on the roadmap and not bookable. What ClipSpeed does today is make the clips and images a Reddit post would link to, and schedule them to YouTube, TikTok, Instagram, X and LinkedIn.
Does ClipSpeed have a Reddit content calendar?
When Reddit 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. Reddit is not bookable yet, so nothing for it appears on the calendar until its badge changes.
Can I cross-post to Reddit and other networks from one request?
When Reddit 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 Reddit 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 Reddit posting slots?
Not as fixed weekly slots yet. When Reddit 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 Reddit 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 Reddit 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 Reddit analytics does ClipSpeed show?
Views, likes, comments and shares per post where Reddit 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 Reddit 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 subreddits on Reddit on your behalf. The assistant drafts within Reddit'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 Reddit guides for each agent below.
Is there an API for Reddit 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 Reddit 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 Reddit 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 Reddit as native video. Generate an image or a short video with ClipSpeed's models and post the result. One conversation, one calendar.
