Post to Reddit from Grok Bot
Grok Bot can post to Reddit through the Postiz plugin. Add the plugin to a Bot, store your Postiz API key as a secret, and name the subreddit. The Bot checks which flairs are available, picks the post type, sets the title, and schedules it in Postiz, cross-posting to several subreddits in one request.
Please make sure there is always a human in the loop.

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 Reddit presence with Postiz.
Own Cloud Computer
Every Bot gets a persistent cloud machine with a terminal. Postiz runs there, so your Reddit 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 Reddit content without being asked twice.
Approvals Built In
Bots ask before changing external systems. Review the Reddit 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 Reddit 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

Message Your Bot
Desktop, iPhone, or a group chat

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

Claude reads the Postiz skill so it knows what it can do, then autonomously discovers your Reddit integration, checks flair requirements, and schedules posts to the right subreddits.

Grok Bot reads the Reddit rules from postiz integrations:settings before scheduling. These are the ones that most often change what gets published.
- ✓Every Reddit target needs a title, a subreddit name without the r/ prefix, and a type of self, link, image, or video.
- ✓Many subreddits require a flair. Grok Bot runs postiz integrations:settings to fetch the live flair list and sets is_flair_required accordingly.
- ✓Reddit titles are limited to 300 characters. Link posts need the url field; image and video posts need media uploaded through postiz upload first.
- ✓Each subreddit has its own rules on self-promotion. Ask the Bot to read the subreddit rules before posting and keep a human in the loop.
Grok Bot and Reddit: frequently asked questions
How do I post to Reddit from Grok Bot?
Add the Postiz plugin with /add-plugin postiz and store your POSTIZ_API_KEY as a Bot secret. Name the subreddit and describe the post. The Bot fetches flairs with postiz integrations:settings, sets the title and post type, and schedules it through Postiz. You approve before publishing.
Can Grok Bot pick the right Reddit flair?
Yes. Before scheduling, the Bot runs postiz integrations:settings for your Reddit channel, which returns the subreddit's flair list. If a flair is required it sets is_flair_required and asks you to choose one, or picks the one you named. Without this step Reddit rejects the post.
Which Reddit post types can Grok Bot create?
Text posts (self), link posts, image posts, and video posts. Say "link post" and give a URL, or point the Bot at an image or video file and it uploads it through postiz upload first. Each subreddit target carries its own type, title, and optional flair.
Can Grok Bot cross-post to multiple subreddits?
Yes. Name several subreddits in one request and the Bot builds a subreddit array with a separate title, type, and flair for each. Postiz publishes them as individual posts. Space them out if you want to avoid looking like spam, and check each subreddit's self-promotion rules.
Can Grok Bot post to Reddit automatically every week?
Yes. Save a routine such as "every Thursday, post our weekly changelog to r/ourproduct". The Bot runs it from its own cloud computer, fetches flairs, schedules through Postiz, and reports back. Approvals keep a human in the loop before anything is published.
