Publish notes to Nostr from ChatGPT
ChatGPT can publish notes on Nostr through ClipSpeed. Add the ClipSpeed connector, sign in, and then ask ChatGPT to publish notes, pick the time, and apply Nostr's settings, without leaving ChatGPT on the web. Nostr is on the roadmap on ClipSpeed's rail; this page describes how it works and says so.
Keep a human in the loop: ChatGPT shows the plan and asks before anything is public. Posting today: YouTube, TikTok, Instagram, X (Twitter) and LinkedIn.

How to publish notes Nostr from ChatGPT
ChatGPT connectors are URLs. Turn on Developer mode, add ClipSpeed as a custom connector, sign in, and the tools appear in any chat where the connector is enabled. Connect Nostr in ClipSpeed, then describe the post. Setup takes about a minute.
# One-time setup: Settings → Connectors → Create (Developer mode)
https://api.clipspeed.ai/mcp
# Then ask ChatGPT:
> Publish a note about the launch at 9am
ChatGPT: Preview — nothing booked yet. Nostr — text. Book it?Developer mode is available on ChatGPT's paid plans on the web. ChatGPT asks you to confirm write actions such as scheduling before they run; keep that on.
- In ChatGPT on the web, open Settings → Connectors → Advanced and turn on Developer mode.
- Back in Connectors, choose Create. Name it ClipSpeed, paste https://api.clipspeed.ai/mcp as the server URL, pick OAuth, and save.
- Click Connect. A ClipSpeed sign-in opens; approve it. No API key is pasted anywhere.
- Connect Nostr in the ClipSpeed app, or ask ChatGPT for a connect link: it is private, valid for ten minutes, and Nostr signs you in itself.

What can ChatGPT do on Nostr?
On Nostr, ChatGPT can publish signed notes with linked media to your relays. Every booking runs through the same rules as the ClipSpeed app.
Text, Image and Video posts
Nostr takes text, image and video through ClipSpeed. Video: linked by URL. Image: linked by URL.
Limits checked at booking
Nostr notes have no protocol limit; most clients truncate near 1,000 characters. Titles are optional.
Exact time or refused
Name the minute and ChatGPT books it, or you are told why not and offered the next open slot. A booked Nostr post is never moved behind your back.
Preview before anything posts
preview: true runs the whole booking and writes nothing. ChatGPT 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 Nostr. No download, no re-upload.
Pacing and numbers
Planned: Text posts on Nostr are at least 30 minutes apart, up to 10 a day. After a post goes out, ChatGPT can read back views and engagement where Nostr provides them.
How does ChatGPT post to Nostr through ClipSpeed?
You describe what you want in plain language and ChatGPT makes the ClipSpeed calls. A typical conversation has three beats.
Find your Nostr channel
Ask ChatGPT whether Nostr is connected. It calls list_channels and reads platform_settings, so it also knows what Nostr accepts and the limits before you write a word.
Compose within the rules
Describe the post. ChatGPT drafts within Nostr'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.
Nostr settings reference
These are the schedule_post fields that apply to Nostr. Mention any of them in plain language and ChatGPT sets them; the server checks them at booking. Fields marked planned land with the Nostr release.
| Field | Type | Required | What it does on Nostr |
|---|---|---|---|
platforms | string[] | Yes | Include "nostr". Up to ten platforms per call; each books its own slot. |
text | string | Yes | The note. No protocol limit; keep it short because clients truncate. |
relays | string[] | Planned | Relays to publish to; defaults to the ones on your connected profile. |
media_url | string | No | A public link; Nostr embeds media by URL. |
scheduled_at | ISO 8601 | No | Exact or refused with the next open slot. |
preview | boolean | No | Plan only. |
Common Nostr configurations
Ask ChatGPT for any of these and it applies the matching settings.

Nostr limits and gotchas to know
Nostr enforces a few rules that ChatGPT and ClipSpeed respect automatically, but knowing them helps you phrase requests.
- Notes are signed with your key. ClipSpeed will use a signing method that never asks for your private key in chat; details land with the release.
- There is no protocol character limit, but clients truncate long notes, so short wins.
- Media is a URL in the note, not an upload; ClipSpeed clips are already hosted.
- Nostr is on ClipSpeed's roadmap, not the next rail. Bookings are refused plainly until it posts.
- A note is published to each relay you choose; a relay that is down simply misses it.
| Rule | Nostr |
|---|---|
| Accepts | Text, Image, Video |
| Text limit | Nostr notes have no protocol limit; most clients truncate near 1,000 characters |
| Title | No title field |
| Links in the caption | Kept; media is linked by URL |
| Pacing | Planned: Text posts on Nostr are at least 30 minutes apart, up to 10 a day. |
| Formats | Image: linked by URL. Video: linked by URL. Aspect: any |
| Status | On the roadmap; described here, not yet bookable |
What Postiz-style schedulers cannot do
Cut the clips first
ChatGPT 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. ChatGPT picks by score, writes the caption from the transcript, and books the clips on Nostr. 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. ChatGPT 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 Nostr. 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: ChatGPT 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.
What is ChatGPT?
ChatGPT is OpenAI's assistant on chatgpt.com and in its desktop and mobile apps. On the web it can reach outside tools through connectors, including custom connectors built on the Model Context Protocol (MCP) when Developer mode is on. With the ClipSpeed connector added, ChatGPT can clip a video, generate images and video, and schedule posts to your connected platforms, confirming each booking before it runs.
How ClipSpeed works with ChatGPT
- ChatGPT discovers the ClipSpeed tools when the connector is enabled in a chat
- It reads each platform's rules with
platform_settingsbefore writing, so limits are met the first time schedule_postbooks an exact time or refuses with the next open slot; a taken slot is never silently movedpreview: truereturns the plan with every slot and books nothing; you confirm and it books- OAuth means ChatGPT never holds a platform password and ClipSpeed never holds your OpenAI login

Nostr and ChatGPT: frequently asked questions
How do I publish notes to Nostr from ChatGPT?
In ChatGPT on the web, open Settings → Connectors → Advanced and turn on Developer mode. Back in Connectors, choose Create. Name it ClipSpeed, paste https://api.clipspeed.ai/mcp as the server URL, pick OAuth, and save. Connect Nostr in ClipSpeed (or ask ChatGPT for a connect link; it is private and valid for ten minutes), then describe the post in plain language. ChatGPT reads the Nostr rules, drafts within them, shows the plan and books on your yes. Nostr is on the roadmap; until the badge changes, the booking is refused with a plain message.
What can ChatGPT post to Nostr through ClipSpeed?
Publish signed notes with linked media to your relays. Nostr takes text, image and video posts.
Which Nostr settings can ChatGPT control?
The fields in the settings reference above: text, relays, media_url, scheduled_at, preview. Mention any of them in plain language ("unlisted", "tomorrow at 9", "preview first") and ChatGPT sets the matching field before it books.
Do I need a Nostr API key or developer account?
No. You connect Nostr to ClipSpeed once through Nostr's own sign-in, and ChatGPT talks to ClipSpeed over OAuth. No Nostr developer key, bearer token or password is pasted anywhere.
How many Nostr posts a day can ChatGPT schedule?
Planned: Text posts on Nostr are at least 30 minutes apart, up to 10 a day. 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 Nostr while I am away?
Yes. Once booked, ClipSpeed publishes at the scheduled minute whether or not ChatGPT 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 Nostr from ChatGPT different from Codex?
The booking is identical: the same rules, the same calendar, the same refusals. What differs is where you work. ChatGPT: chatgpt.com (developer mode for custom connectors). Codex: terminal, ide, codex.openai.com, reads your repo; codex exec runs a prompt unattended for cron and ci.
