Grok Bot is the always-on AI teammate product from xAI and Cursor. You create named Bots, give each one a job, and they work 24/7 on their own persistent cloud computer — with a browser, a filesystem, and a terminal — pinging you only when they need approval.
Grok Bot is not the Grok chatbot. Grok is the assistant you chat with on X and grok.com. Grok Bot is a separate app for delegating real, multi-step work — like running your Facebook presence with Postiz.
Own Cloud Computer
Every Bot gets a persistent cloud machine with a terminal. Postiz runs there, so your Facebook posts go out even when your laptop is closed.
Routines
Turn any task into a routine that runs on a schedule. Your Bot drafts, schedules, and reports on Facebook content without being asked twice.
Approvals Built In
Bots ask before changing external systems. Review the Facebook posts your Bot prepared in Postiz, approve, and it publishes.
How Postiz Works with Grok Bot
Postiz is listed on the Grok Bot plugin marketplace. Add it to a Bot and the Postiz skill, CLI, and command reference are installed on its cloud computer — the Bot can then manage your Facebook workflow on its own.
- ✓Type /add-plugin postiz in a Bot chat, or add it from the Plugins sidebar
- ✓Store your POSTIZ_API_KEY as a Bot secret when prompted
- ✓The Bot reads the bundled SKILL.md and learns every Postiz command
- ✓Works in every Bot on your shared workspace, on desktop and iPhone
- ✓Approvals keep a human in the loop before anything is published

Postiz works with any AI agent that can run commands or call MCP tools — you ask, the agent does the work. That includes Anthropic's Claude Code. See the Claude Code guide for Facebook, the guide for any AI agent, or connect over the Postiz MCP server.
Claude Code

Claude reads the Postiz skill so it knows what it can do, then autonomously discovers your Facebook integration, composes your post with a link preview if needed, and schedules the post.

Grok Bot: Routine saved: monday-facebook-events.Facebook rules Grok Bot follows
Grok Bot reads the Facebook rules from postiz integrations:settings before scheduling. These are the ones that most often change what gets published.
- ✓Postiz posts to Facebook Pages you manage, not personal profiles. Connect the Page in Postiz before asking the Bot.
- ✓Use the url field for rich link previews. If you paste a link in the text only, Facebook may not render the preview card.
- ✓Images and video must be uploaded with postiz upload first; the Bot cannot attach a raw local path or external URL.
- ✓Run postiz integrations:settings before scheduling. Postiz returns the current Facebook rules and Grok Bot honors them.
Grok Bot and Facebook: frequently asked questions
How do I post to Facebook from Grok Bot?
Add the Postiz plugin with /add-plugin postiz and store your POSTIZ_API_KEY as a Bot secret. Ask the Bot to post to your Facebook Page. It finds the Page in Postiz, writes the copy, attaches a link preview or media, and schedules it. You approve before it publishes.
Can Grok Bot post to a Facebook Page or only a profile?
Postiz connects Facebook Pages, so Grok Bot posts to Pages you manage. Connect each Page in Postiz and it shows up in integrations:list. If you run several Pages, name the one you mean and the Bot targets it, or post the same update to all of them.
Can Grok Bot add a link preview to Facebook posts?
Yes. Give the Bot a URL and it sets the url field so Facebook renders a rich link card with the page title and image. This is more reliable than pasting the link inside the text. You can still add your own intro copy above the preview.
Can Grok Bot attach photos or video to Facebook posts?
Yes. Point the Bot at a file on its cloud computer or in your workspace. It runs postiz upload first, then attaches the returned media to the post. Supported formats include PNG, JPG, MP4, and MOV. Raw paths and external URLs are not accepted by Postiz.
Can Grok Bot post to Facebook on a schedule while I am away?
Yes. Save the task as a routine and the Bot runs it from its own cloud computer, drafting the post, scheduling it through Postiz, and reporting back. It asks for approval before publishing, so a human stays in the loop even when the routine runs unattended.
