From ChatGPT draft to Instagram queue
The writing already happens in ChatGPT. With the public API or the CLI, the same conversation can create scheduled Instagram posts, stories and reels instead of text to paste.
InstagramAutomate Instagram with ChatGPT
Draft Instagram posts, stories and reels in ChatGPT, then let postqueen schedule and publish them. One conversation in, a full Instagram queue out.
Quick start
Point a custom GPT action at the public API, or let agent modes that run commands use the CLI for Instagram.
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 instagram-week.jsonWhat ChatGPT can run on Instagram
Windows that fit Instagram
Tell ChatGPT when your followers are most active and it schedules posts into that window on Instagram, day after day, without reminders.
Media attached, sized right
Images upload in the same postqueen call, so Instagram posts, stories and reels 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 Instagram until you do.
Three steps to a full queue
Discover Instagram
ChatGPT calls postqueen to list your connected accounts and sees what Instagram supports, so drafts start from real capabilities, not guesses.
Draft with ChatGPT
Give it the brief. The agent writes Instagram-shaped posts, stories and reels 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.
What Instagram allows
ChatGPT reads these limits from postqueen before it composes, so a draft that would be rejected never reaches the queue.

F.A.Q.
Frequently asked questions
How does ChatGPT connect Instagram 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 Instagram posts, stories and reels end to end.
Can ChatGPT schedule Instagram 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 Instagram 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 Instagram and other channels too?
Yes. postqueen connects 30 channels, so ChatGPT can turn the same brief into Instagram posts, stories and reels 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 the AI write Instagram captions and hashtags?
Yes. The built-in assistant drafts captions in your tone, suggests hashtag sets and rewrites anything you highlight. Nothing publishes until you schedule it, and agents like Claude Code or OpenClaw can generate whole batches through the MCP server.
Can I cross-post reels to TikTok and YouTube Shorts?
Yes. Compose the vertical video once, select Instagram, TikTok and YouTube as destinations, and adjust the caption per platform before scheduling. Each network gets its own native upload, not a watermarked repost.
