How to post Reddit from OpenAI dots
A dot uses the connectors on your ChatGPT account. Add ClipSpeed as a custom connector, then give the dot a job that uses it. Connect Reddit in ClipSpeed, then describe the post. Setup takes about a minute.
# One-time setup: ChatGPT → Settings → Connectors (Developer mode)
https://api.clipspeed.ai/mcp
# Then ask OpenAI dots:
> Post the write-up to r/SideProject with the Showcase flair at 10am
OpenAI dots: Preview — nothing booked yet. Reddit — title. Book it?ClipSpeed has not yet run an end-to-end check with a dot. The connector itself is verified in ChatGPT.
- In ChatGPT on the web, turn on Developer mode and add ClipSpeed as a custom connector with the URL.
- Sign in to ClipSpeed when asked.
- Create a dot with a job such as: every night at 11, clip today's recordings and plan tomorrow's posts with preview.
- Connect Reddit in the ClipSpeed app, or ask OpenAI dots for a connect link: it is private, valid for ten minutes, and Reddit signs you in itself.

What can OpenAI dots do on Reddit?
On Reddit, OpenAI dots can post titled text, link, image and video posts to subreddits with a flair. Every booking runs through the same rules as the ClipSpeed app.
Text, Image and Video posts
Reddit takes text, image and video through ClipSpeed. Video: MP4 up to 1 GB. Image: JPG, PNG or GIF.
40,000 characters, checked at booking
Reddit's own arithmetic. Too long is refused with the real count, never trimmed at send time. Titles are required and cap at 300.
Exact time or refused
Name the minute and OpenAI dots books it, or you are told why not and offered the next open slot. A booked Reddit post is never moved behind your back.
Preview before anything posts
preview: true runs the whole booking and writes nothing. OpenAI dots 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 Reddit. No download, no re-upload.
Pacing and numbers
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. After a post goes out, OpenAI dots can read back views and engagement where Reddit provides them.
How does OpenAI dots post to Reddit through ClipSpeed?
You describe what you want in plain language and OpenAI dots makes the ClipSpeed calls. A typical conversation has three beats.
Find your Reddit channel
Ask OpenAI dots whether Reddit is connected. It calls list_channels and reads platform_settings, so it also knows what Reddit accepts and the limits before you write a word.
Compose within the rules
Describe the post. OpenAI dots drafts within Reddit'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.
Reddit settings reference
These are the schedule_post fields that apply to Reddit. Mention any of them in plain language and OpenAI dots sets them; the server checks them at booking. Fields marked planned land with the Reddit release.
| Field | Type | Required | What it does on Reddit |
|---|---|---|---|
platforms | string[] | Yes | Include "reddit". Up to ten platforms per call; each books its own slot. |
title | string | Yes | Up to 300 characters. |
text | string | No | The body for a text post, up to 40,000 characters of Markdown. |
subreddit | string | Planned | Where to post. |
flair | string | Planned | A flair the subreddit offers; some require one. |
media_kind | text | image | video | No | Detected from the file when omitted. |
clip_id or media_url | string | No | A clip or a public link; a URL alone makes a link post. |
scheduled_at | ISO 8601 | No | Exact or refused with the next open slot. |
preview | boolean | No | Plan only. |

Reddit limits and gotchas to know
Reddit enforces a few rules that OpenAI dots and ClipSpeed respect automatically, but knowing them helps you phrase requests.
- 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.
- Reddit's API access terms for third-party posting are stricter than most; the release date depends on them.
| Rule | |
|---|---|
| Accepts | Text, Image, Video |
| Text limit | 40,000 characters |
| Title | 300 characters, required |
| Links in the caption | A link post is its own type; text posts keep links |
| Pacing | 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. |
| Formats | Image: JPG, PNG or GIF. Video: MP4 up to 1 GB. Aspect: any |
| Status | On the roadmap; described here, not yet bookable |
What Postiz-style schedulers cannot do
Cut the clips first
OpenAI dots 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. OpenAI dots 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. OpenAI dots shows the plan with preview: true, you say yes, it books.generate_image or generate_videoDescribe the shot.

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: OpenAI dots 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.

Reddit and OpenAI dots: frequently asked questions
How do I post to Reddit from OpenAI dots?
In ChatGPT on the web, turn on Developer mode and add ClipSpeed as a custom connector with the URL. Sign in to ClipSpeed when asked. Connect Reddit in ClipSpeed (or ask OpenAI dots for a connect link; it is private and valid for ten minutes), then describe the post in plain language. OpenAI dots reads the Reddit rules, drafts within them, shows the plan and books on your yes. Reddit is on the roadmap; until the badge changes, the booking is refused with a plain message.
What can OpenAI dots post to Reddit through ClipSpeed?
Post titled text, link, image and video posts to subreddits with a flair. Reddit takes text, image and video posts. Text is limited to 40,000 characters. A title is required and is capped at 300 characters.
Which Reddit settings can OpenAI dots control?
The fields in the settings reference above: title, text, subreddit, flair, media_kind, clip_id or media_url, scheduled_at, preview. Mention any of them in plain language ("unlisted", "tomorrow at 9", "preview first") and OpenAI dots sets the matching field before it books.
Do I need a Reddit API key or developer account?
No. You connect Reddit to ClipSpeed once through Reddit's own sign-in, and OpenAI dots talks to ClipSpeed over OAuth. No Reddit developer key, bearer token or password is pasted anywhere.
How many Reddit posts a day can OpenAI dots schedule?
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. 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 OpenAI dots post to Reddit from a script or a cron job?
Yes. OpenAI dots's headless mode (dot job) runs one prompt and exits, and the ClipSpeed server registered on that machine does the booking. On a runner with no browser, authenticate with a ClipSpeed API key header. Keep preview on so the run reports a plan before it books.
Is posting to Reddit from OpenAI dots different from ChatGPT?
The booking is identical: the same rules, the same calendar, the same refusals. What differs is where you work. OpenAI dots: inside chatgpt. ChatGPT: chatgpt.com, interactive.
