From ChatGPT draft to Bluesky queue
The writing already happens in ChatGPT. With the public API or the CLI, the same conversation can create scheduled Bluesky posts instead of text to paste.
BlueskyAutomate Bluesky with ChatGPT
Draft Bluesky posts in ChatGPT, then let postqueen schedule and publish them. One conversation in, a full Bluesky queue out.
Quick start
Point a custom GPT action at the public API, or let agent modes that run commands use the CLI for Bluesky.
Custom GPT or CLI
# Custom GPT action: call the public APIPOST https://api.postqueen.ai/public/v1/postsAuthorization: your_api_key # Or in agent modes that run commands:npm install -g postqueenpostqueen posts:create --json bluesky-week.jsonWhat ChatGPT can run on Bluesky
Windows that fit Bluesky
Tell ChatGPT when your followers are most active and it schedules posts into that window on Bluesky, day after day, without reminders.
Media attached, sized right
Images upload in the same postqueen call, so Bluesky posts arrive with their media in place instead of a bare link.
Drafts until you are ready
Ask ChatGPT for drafts only. They sit on the postqueen calendar unscheduled, so you can edit them and pick the time yourself, and nothing reaches your followers on Bluesky until you do.
Three steps to a full queue
Discover Bluesky
ChatGPT calls postqueen to list your connected accounts and sees what Bluesky supports, so drafts start from real capabilities, not guesses.
Draft with ChatGPT
Give it the brief. The agent writes Bluesky-shaped posts and proposes publish times that match when your followers are around.
Check and publish
Look over the queue on the postqueen calendar and change anything you want. postqueen publishes each post at its time, and ChatGPT can pull the results after.

F.A.Q.
Frequently asked questions
How does ChatGPT connect Bluesky to postqueen?
Through the public API from a custom GPT action, or through the CLI in agent modes that execute commands. Both use the same API key and cover Bluesky posts end to end.
Can ChatGPT schedule Bluesky posts at exact times?
Yes. Give it exact slots or a rule like mornings at nine and it sets publish times on the posts it creates, so your followers see them at the right moment.
Will ChatGPT publish to Bluesky on its own?
Only if you ask it to. Tell it to save drafts and nothing is scheduled: the posts wait on the calendar until you set a time. Tell it to schedule, and they go out at the times you can see, which is the setup most people move to once they trust the output.
Can one brief cover Bluesky and other channels too?
Yes. postqueen connects 30 channels, so ChatGPT can turn the same brief into Bluesky posts plus adapted versions for every other channel you run.
Does ChatGPT access cost extra on postqueen?
No. The agent uses your regular API key and plan limits: unlimited posts on every plan, and channel counts from 5 on Creator up to uncapped on Ultimate.
Can I cross-post to X, Threads and Mastodon at the same time?
Yes. Compose once, select every channel, and tweak each version before it publishes. Bluesky's 300 character limit is the tightest of the group, so postqueen lets you trim that version separately without touching the others.
Can the AI assistant write Bluesky posts?
Yes. Drafts come out short, plain and inside the 300 character limit, in a tone that fits Bluesky. You edit everything and pick its time, and the same flow works from the CLI or through the built-in MCP server for agents.
