Post to X (Twitter) from Grok Bot

Grok Bot can post to X (Twitter) through the Postiz plugin. Add the plugin to a Bot, store your Postiz API key as a secret, and ask in plain language. The Bot schedules tweets and threads, sets who can reply, targets X Communities, and keeps posting from its own cloud computer on a routine.

How to post to X from Grok Bot

Add the Postiz plugin once, then tell your Bot what to tweet. It finds your X channel in Postiz, applies the reply setting you asked for, and schedules the post.

Setup, then just ask

# One-time setup, in any Bot chat
/add-plugin postiz
# Store POSTIZ_API_KEY as a Bot secret when prompted

# Then just ask Grok Bot:
> Post a thread about our launch on X,
  schedule it for tomorrow at 9am

Grok Bot: Done! Your X post is scheduled.

How does Grok Bot post to X?

Grok Bot: Yes — your X account is connected
  and ready. Want me to post something?

Compose Your Content

  "We just shipped something big..."
  Want me to add media and schedule it?

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 X presence with Postiz.

💻

Own Cloud Computer

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

🛡️

Approvals Built In

Bots ask before changing external systems. Review the X 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 X 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 X channel in Postiz

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

How Grok Bot runs X on a routine

Your Bot reads the Postiz skill, discovers your X 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 X account via Postiz, uploads your media, and schedules the post — then asks you to approve before it goes live.

Grok Bot

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

Bot: Got it! Here's the plan:
  1. Find your X 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 X automatically — no manual trigger needed.

Grok Bot routine

Routine: daily-x-posts
Schedule: Weekdays at 9:00 AM

Instructions:
  Check ~/content/posts on your cloud
  computer for new .txt files. For
  each one, read the content and
  schedule a post to X for
  today at noon via Postiz. Move
  posted files to ~/content/published
  and send me a summary.

Why Grok Bot + Postiz for X

Grok Bot makes Postiz a natural fit for your X workflow. The Bot reads the plugin's skill, chains the right commands together, and keeps running from the cloud.

✓Official plugin — one command install from the marketplace
✓Always on — posts to X from the cloud while you are away
✓Terminal access runs Postiz commands directly on the Bot's computer
✓Routines for hands-free daily posting
✓Cross-post to X + other platforms in a single conversation
✓Approvals keep a human in the loop before publishing

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 X, 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 X integration, composes your tweet or thread, applies reply settings, and schedules the post.

Claude Code

> Post a thread about our product launch
  on X, schedule for tomorrow, everyone
  can reply

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

Cross-post X content to other platforms

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

Example

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

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

Example prompts for X in Grok Bot

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

Schedule a thread with reply controls

Grok Bot chat

> Turn ./notes/launch.md into a 5-tweet thread
  on X, schedule it for Tuesday 9am, and only
  let people I follow reply

Grok Bot: Drafted 5 tweets, each under 280
  characters. who_can_reply_post: following.
  Scheduled for Tuesday 9:00 AM. Approve?

Daily tips as a routine

Grok Bot chat

> Every weekday at 10am, pick one unused tip
  from ~/content/tips.csv and post it to X.
  Mark it used and message me the link.

Grok Bot: Routine saved: weekday-x-tips.
  Runs at 10:00 AM Mon-Fri on my cloud computer.

X rules Grok Bot follows

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

✓who_can_reply_post is required on every X post. If you do not say who can reply, the Bot defaults to everyone.
✓Standard X accounts are limited to 280 characters per post. Ask for a thread when the message is longer and Grok Bot splits it into ordered tweets.
✓Community posts need the full X Community URL in the community field. Ask the Bot to confirm the community before scheduling.
✓Images and video must go through postiz upload first. The Bot cannot attach a raw file path or an external URL directly to an X post.

Grok Bot and X: frequently asked questions

How do I post to X from Grok Bot?

Type /add-plugin postiz in any Bot chat, store your POSTIZ_API_KEY as a Bot secret, and ask the Bot to post. It runs postiz integrations:list to find your X channel, composes the tweet, applies reply settings, and schedules it through Postiz. You approve before anything goes live.

Can Grok Bot post X threads?

Yes. Ask for a thread and Grok Bot splits your content into separate tweets, each within the character limit, and Postiz publishes them in order as a connected thread. You can attach different media to each tweet and set one who_can_reply_post value for the whole thread.

Is Grok Bot the same as Grok on X?

No. Grok is the chatbot you talk to on X and grok.com. Grok Bot is the always-on agent product from xAI and Cursor, with its own cloud computer and plugins. Posting to X with Postiz uses Grok Bot, not the Grok chatbot, and does not require X Premium.

Can Grok Bot control who replies to my tweets?

Yes. Say who can reply and the Bot sets who_can_reply_post to everyone, following, mentionedUsers, subscribers, or verified. The setting is required on X, so if you do not mention it the Bot uses everyone. You can also target an X Community by giving the community URL.

Can Grok Bot keep tweeting while I am offline?

Yes. Save the task as a routine and the Bot runs it on a schedule from its own cloud computer, even when your laptop is closed. It reads your drafts, schedules tweets through Postiz, and reports back in chat. Approvals keep a human in the loop before publishing.
