What is Grok Bot?

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 YouTube presence with Postiz.

💻

Own Cloud Computer

Every Bot gets a persistent cloud machine with a terminal. Postiz runs there, so your YouTube 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 YouTube content without being asked twice.

🛡️

Approvals Built In

Bots ask before changing external systems. Review the YouTube 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 YouTube 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

Grok Bot

# 1. Add the plugin to your Bot
/add-plugin postiz

# 2. Store your Postiz API key
#    as a secret when prompted

# 3. Ask your Bot to verify
You: Find my YouTube channel in Postiz

Bot: Running postiz integrations:list
  Found your YouTube integration.
  All Postiz commands are ready.

How Grok Bot runs YouTube on a routine

Your Bot reads the Postiz skill, discovers your YouTube integration, and handles the entire posting workflow — from content creation to scheduling — on its own cloud computer.

🧠

Message Your Bot

Desktop, iPhone, or a group chat

Send a message to your Bot from the desktop app or your iPhone. It runs on its own cloud computer, so it picks up your message, discovers your YouTube account via Postiz, uploads your media, and schedules the post — then asks you to approve before it goes live.

Grok Bot

You: Post to YouTube about our new
  feature launch, schedule for tomorrow
  at 9am

Bot: Got it! Here's the plan:
  1. Find your YouTube integration
  2. Compose your post content
  3. Schedule for tomorrow 9:00 AM

  Done! Post scheduled successfully.
  Post ID: abc-123

🧠

Routines

Recurring work on a schedule

Save the task as a routine. Your Bot runs it on a schedule from the cloud, checks for new content, and posts it to YouTube automatically — no manual trigger needed.

Grok Bot routine

Routine: daily-youtube-posts

Also Works with Claude Code

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 YouTube, the guide for any AI agent, or connect over the Postiz MCP server.

Claude Code

by Anthropic

Claude reads the Postiz skill so it knows what it can do, then autonomously discovers your YouTube integration, uploads your video and thumbnail, applies tags and visibility settings, and schedules the upload.

Claude Code

> Upload my tutorial video to YouTube
  as public with tags "coding" and
  "tutorial", schedule for tomorrow

Claude: Done! Scheduled on YouTube for
  tomorrow at 9:00 AM.

Cross-post YouTube content to other platforms

Schedule the same video to YouTube and other platforms in a single request. Each platform gets its own settings.

Example

> Post "Excited to announce our new feature!" to
  YouTube and LinkedIn tomorrow at 9am, then schedule
  a daily tip on YouTube every weekday at 10am

Grok Bot: Done! Scheduled:
  - YouTube + LinkedIn: tomorrow 9:00 AM
  - Daily tips on YouTube: Mon-Fri 10:00 AM

Example prompts for YouTube in Grok Bot

These are prompts you can paste into a Bot chat. Grok Bot maps each one to the matching Postiz commands and YouTube settings, then asks for approval.

Grok Bot chat

> Upload ~/videos/tutorial-01.mp4 to YouTube

Grok Bot chat

  Link will be ready after publish.

YouTube rules Grok Bot follows

Grok Bot reads the YouTube rules from postiz integrations:settings before scheduling. These are the ones that most often change what gets published.

✓YouTube titles must be 2 to 100 characters and are required. Grok Bot trims or asks when a title runs long.
✓type is required and must be public, unlisted, or private. Ask for unlisted when you want to review before sharing.
✓Custom thumbnails need a separate postiz upload; the Bot then passes the thumbnail id and path. Video files must also be uploaded through Postiz first.
✓selfDeclaredMadeForKids is a legal declaration. Tell the Bot yes or no explicitly rather than letting it guess.

Grok Bot and YouTube: frequently asked questions

How do I upload to YouTube from Grok Bot?

Add the Postiz plugin with /add-plugin postiz and store your POSTIZ_API_KEY as a Bot secret. Point the Bot at a video and give it a title. It runs postiz upload, sets type, tags, and thumbnail, and schedules the publish time through Postiz. You approve before it goes live.

Can Grok Bot set a custom YouTube thumbnail?

Yes. Give the Bot an image file and it uploads it through Postiz, then sets thumbnail.id and thumbnail.path on the post. The video itself is uploaded the same way. Both files must go through postiz upload; the Bot cannot pass a raw path or external URL.

Can Grok Bot schedule YouTube videos as unlisted or private?

Yes. The type field accepts public, unlisted, or private. Ask for unlisted when you want a shareable review link, or private when only your account should see it. You can later ask the Bot to publish the video publicly with a new post.

Does Grok Bot handle the made-for-kids declaration?

Yes, but only when you tell it. The selfDeclaredMadeForKids field takes yes or no and is a legal declaration under COPPA rules, so say it explicitly in your request. Grok Bot will not guess this value and asks if it is missing.

Can Grok Bot upload YouTube videos on a recurring schedule?

Yes. Save a routine that watches a folder on the Bot's cloud computer, uploads new renders through Postiz, and schedules them with titles and tags from your notes. The Bot reports back in chat and asks for approval before each publish, keeping a human in the loop.
