ChatGPTChatGPT + Postiz

Schedule Social Media Posts with ChatGPT

  • Official Postiz app or custom MCP connector
  • Draft, schedule and publish posts by asking
  • 30+ platforms: X, LinkedIn, Instagram, Reddit

Postiz is the agentic social media scheduling platform that ChatGPT drives through the Postiz connector and MCP server. Please make sure there is always a human in the loop. Last updated: September 2026.

How do I connect Postiz to ChatGPT?

Add the official Postiz app from the ChatGPT directory in one click, or turn on Developer mode and paste the MCP link as a custom connector. Both sign in with your Postiz account over OAuth, so there is no API key to copy and nothing to install.

Add Postiz to ChatGPT

Fastest: add the official Postiz app. Prefer a custom connector? Paste this MCP link under Settings → Connectors.

One click instead? Add the official Postiz app to ChatGPT. No API key needed either way: sign in to Postiz when ChatGPT asks you to approve access. Custom MCP connectors need ChatGPT Developer mode (Plus, Pro, Business, Enterprise, and Edu plans on the web). The same link also works in any other MCP client.

Then just ask ChatGPT

Once connected, ChatGPT calls the Postiz tools. Scheduled posts publish on time even after you close the chat.

Schedule a post to X and LinkedIn for tomorrow at 9am announcing our new feature. Keep it short and upbeat.

Official Postiz app or custom MCP link?

Use the official app if you want the fastest setup. Use the custom MCP link if you already run other MCP servers in ChatGPT Developer mode or want to inspect each tool call before it runs.

What can ChatGPT do with Postiz?

ChatGPT can write, schedule, and publish posts, attach generated media, and plan a content calendar, all through the Postiz tools it discovers once the connector is added.

Just Ask in Plain English

Tell ChatGPT what to post and when. It writes it, schedules it, and publishes it through Postiz — no menus, no forms.

30+ Platforms

Post to X, LinkedIn, Reddit, Instagram, YouTube, TikTok, and more — all from a single conversation with ChatGPT.

Official Connector, One Click

No installs or technical setup. Add the official Postiz connector from ChatGPT and you're ready to go.

Plan & Schedule Ahead

Ask ChatGPT to plan a week of content and pick the times. It schedules everything in Postiz so it goes out automatically.

Generate Images & Videos

ChatGPT can generate images and videos through Postiz and attach them to your posts — all in the same request.

Stays in Your Account

The connector signs in with your own Postiz account, so ChatGPT only touches the accounts you've already connected.

What is the Postiz MCP?

The Postiz MCP server is the link that turns ChatGPT into a social media agent. MCP (Model Context Protocol) is the standard way AI assistants plug into the apps you use. The Postiz MCP server exposes your social media accounts to ChatGPT as tools — so it can post, schedule, and report without you ever opening a dashboard. Read more on the Postiz MCP page.

How ChatGPT Uses Postiz

Once the Postiz connector is added, ChatGPT discovers the Postiz tools automatically and calls them on your behalf when you ask it to post.

  • Add the official Postiz connector (or your MCP link) in ChatGPT
  • ChatGPT discovers your connected accounts and platform rules
  • It composes posts with the right format for each platform
  • It schedules, drafts, or publishes — exactly as you asked
  • Works alongside ChatGPT's other tools and connectors

What can you ask ChatGPT to post?

Which platforms can ChatGPT post to?

Is ChatGPT the same as Codex?

No. ChatGPT is OpenAI's chat assistant and connects to Postiz as an app or MCP connector. Codex is OpenAI's coding agent for the terminal and IDE, and it drives Postiz through the Postiz CLI and MCP tools instead.

Frequently asked questions about ChatGPT and Postiz

How does Postiz work with ChatGPT?

Postiz is an official ChatGPT connector, so ChatGPT can act as your social media agent. Add the Postiz app from the ChatGPT directory or paste the Postiz MCP link as a custom connector, sign in with your Postiz account, and ChatGPT can draft, schedule, and publish posts to 30+ platforms from a normal conversation.

How do I connect Postiz to ChatGPT?

The quickest way is the official Postiz app: open the Add to ChatGPT link, click Connect, then sign in to Postiz and approve access. To add it manually, turn on Developer mode in ChatGPT, open Settings → Connectors, add a custom connector, and paste https://mcp.postiz.com/mcp-oauth-dynamic. No API key is needed either way.

Do I need a paid ChatGPT plan to use Postiz?

The official Postiz app is added from the ChatGPT directory like any other app. The custom MCP connector route needs ChatGPT Developer mode, which OpenAI offers on Plus, Pro, Business, Enterprise, and Edu accounts on the web. Postiz itself is separate: start for $0 with a 7-day free trial.

Is ChatGPT the same as Codex?

No. ChatGPT is OpenAI's chat assistant, so you connect Postiz as an app or MCP connector and post by chatting on chatgpt.com. Codex is OpenAI's coding agent that runs in your terminal or IDE and drives Postiz through the Postiz CLI and MCP tools, which suits scripted and automated workflows. See postiz.com/codex for that setup.

What can ChatGPT do with Postiz?

ChatGPT can draft, schedule, and publish posts, build threads and comments, apply platform-specific settings such as a Reddit subreddit or a YouTube title, generate images and videos through Postiz, and plan a full content calendar across 30+ platforms. You describe the outcome in plain English and ChatGPT calls the matching Postiz tools.

Can ChatGPT post to social media on a schedule while I am away?

Yes for scheduled posts. When ChatGPT schedules a post, Postiz stores it and publishes at the chosen time even if the chat is closed. For fully unattended, cron-style workflows where an agent decides what to post without you, pair Postiz with a headless agent such as Codex or Claude Code through the Postiz Agent CLI or MCP server.

Is it safe? Does ChatGPT need my social media passwords?

Yes, and no passwords are shared. The connector signs in with your own Postiz account over OAuth, so ChatGPT never sees your social media logins or an API key and can only reach channels you already connected in Postiz. In Developer mode, ChatGPT asks you to confirm write actions such as publishing. Keep a human in the loop.

Which social media platforms can ChatGPT post to?

Any channel connected to your Postiz account. Postiz supports 30+ platforms, including X (Twitter), LinkedIn, Instagram, Facebook, Threads, Bluesky, Reddit, YouTube, TikTok, Pinterest, Discord, Slack, Telegram, Mastodon, Medium, Dev.to, WordPress, and Google My Business. Connect the accounts once in Postiz, then ask ChatGPT to post to any of them by name.

ChatGPT does not show the Postiz tools. What should I check?

First confirm you finished the Postiz sign-in and approved access when ChatGPT opened the OAuth window. Then check that the Postiz connector is enabled for the current chat. If you used the custom MCP link, make sure Developer mode is still on. Removing and re-adding the connector from Settings → Connectors refreshes the tool list.

Is it free to start?

Yes. Create a Postiz account and start for $0 with a 7-day free trial. The Postiz MCP server and the ChatGPT connector are included with every account at no extra cost. See postiz.com/pricing for the current plans and what each one includes.
