Post to social media from ChatGPT
Connect PostJay to ChatGPT and just say what to post. ChatGPT drafts your captions and schedules to 13 platforms over MCP or the REST API.
ChatGPT can write a month of posts in seconds — but it stops at the text box. PostJay lets ChatGPT actually schedule and publish, so "draft my week of content" becomes "draft it and queue it," without ever opening a scheduler.
Connect PostJay through MCP or its REST API and ChatGPT can list your accounts, draft on-brand captions and schedule across all 13 networks. Real posting via each platform's official API — you approve, PostJay publishes.
Why post from ChatGPT with PostJay
MCP or REST API
Connect PostJay as an MCP server, or call the REST API from a custom GPT action or your own script. Either way, ChatGPT can schedule for real.
Draft and queue in one step
Ask ChatGPT to write your posts and drop them into your calendar at the right times — no exporting, no copy-pasting into a separate tool.
13 platforms, tailored per network
Publishes to Instagram, TikTok, YouTube, LinkedIn, Facebook, Pinterest, Threads, Bluesky, X, Mastodon, Discord, Telegram and Tumblr, adapting length and format per platform instead of one identical post everywhere.

ChatGPT + PostJay FAQ
Can ChatGPT schedule social media posts?
Yes, with PostJay. ChatGPT drafts the content, and PostJay's MCP server or REST API does the actual scheduling and publishing to 13 platforms. You connect it once, then ask ChatGPT to write and queue posts in plain language.
How do I connect PostJay to ChatGPT?
Add PostJay as an MCP connector, or wire the REST API (postjay.com/api/v1) into a custom GPT action, using your PostJay API key. Both are documented in the API & MCP guide, available from the $9/mo Starter plan.
Does ChatGPT post automatically without approval?
No — ChatGPT proposes the posts and times, and nothing goes live until you confirm. You can also send posts through PostJay's client-approval flow for a second sign-off before publishing.
Which platforms are supported?
All 13: Instagram, TikTok, YouTube, LinkedIn, Facebook, Pinterest, Threads, Bluesky, X, Mastodon, Discord, Telegram and Tumblr. ChatGPT can schedule to any of them, tailoring each post per platform rather than blasting identical copy everywhere.
