Schedule social media from ChatGPT
PostSyncer is an official app in the ChatGPT app directory. Install it once and ChatGPT can write, schedule, and publish posts to 11+ networks through your connected PostSyncer accounts, then report back on how they performed — all inside the chat.
Connect ChatGPT in three steps
-
1
Install the PostSyncer app in ChatGPT
Click "Open in ChatGPT" above (or search "PostSyncer" under Apps in ChatGPT) and press Install. Sign in to PostSyncer when prompted — that is the whole setup. No connector URL to paste, no API key.
-
2
Connect the accounts ChatGPT should publish to
In PostSyncer, connect Instagram, TikTok, YouTube, X, LinkedIn, Facebook, Threads, Bluesky, Pinterest, Telegram, or Mastodon. Platform credentials stay with PostSyncer's official API integrations — ChatGPT never sees them.
-
3
Ask ChatGPT to run your calendar
"@PostSyncer take these three product screenshots, write platform-native captions, and schedule them for Tuesday mornings." ChatGPT uploads the media, writes per-network variants, and books the slots. Review anything in the PostSyncer calendar.
Prefer a custom connector instead of the app? In ChatGPT open Settings → Connectors → Create and use the
MCP endpoint: https://postsyncer.com/mcp
— works as an OAuth connector or with Authorization:
Bearer <token>. Prefer raw HTTP? Use the
REST API.

Frequently Asked Questions
ChatGPT and PostSyncer — common questions
Install the official PostSyncer app from the ChatGPT app directory: open PostSyncer in ChatGPT and click Install, or search "PostSyncer" under Apps in ChatGPT. Sign in to PostSyncer once and ChatGPT gets every tool — posts, media, comments, campaigns, and analytics — automatically. Prefer a custom connector? Settings → Connectors → Create with https://postsyncer.com/mcp still works.
Installing the app is free. Publishing goes through your PostSyncer account, so you need a PostSyncer plan (there is a free trial) with at least one connected social account. Mention @PostSyncer in any chat to use it.
Yes — ChatGPT can create and schedule posts to every network you have connected in PostSyncer: Instagram, TikTok, YouTube, X (Twitter), LinkedIn, Facebook, Threads, Bluesky, Pinterest, Telegram, and Mastodon. It can also write per-platform content variants in the same request.
Yes. ChatGPT can import media from URLs into your PostSyncer media library or attach existing library items to posts. PostSyncer handles each platform's format, size, and processing requirements.
Significantly. ChatGPT never sees your platform credentials — it calls typed MCP tools against PostSyncer, which publishes through official platform APIs. Every action is scoped to your workspaces, logged, and revocable by disconnecting the connector.
Anything on the OpenAI side that can call MCP servers or plain REST works: point it at the MCP endpoint, or use the PostSyncer REST API directly with a Bearer token for full programmatic control.
