Post to Reddit from Perplexity Computer

Perplexity Computer can schedule and publish Reddit posts through Postiz. Connect Postiz as a custom MCP connector in Perplexity or install the Postiz CLI skill, then name the subreddit and describe the post. Computer looks up the subreddit's flairs, picks a text, link, image, or video post type, sets the title, and schedules it to one or several communities.

Setup Guide

Please make sure there is always a human in the loop.

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.

Claude Code

by Anthropic

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.

Claude Code

> Post to r/programming and r/webdev
  about our new feature, schedule for
  tomorrow morning

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

Reddit + Other Platforms

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

Example

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

Perplexity Computer: Done! Scheduled:
  - Reddit + LinkedIn: tomorrow 9:00 AM
  - Daily tips on Reddit: Mon-Fri 10:00 AM

What can you ask Perplexity Computer to do on Reddit?

You can ask Perplexity Computer for anything Postiz can do on Reddit: draft, schedule, publish, attach media, and set Reddit-specific options. These are prompts people actually type.

You say

> What flairs does r/webdev require, and post our
  guide there with the Showoff flair

Computer calls the Postiz settings for your Reddit channel, lists the available flairs, then sets is_flair_required and the flair id before creating the post.

You say

> Share https://example.com/launch as a link post to
  r/SideProject and r/startups with different titles

Computer creates one Postiz post with two subreddit targets, each with type link, its own title, and the URL.

You say

> Post demo.mp4 to r/InternetIsBeautiful as a video
  post Sunday at 2pm

Computer uploads the video through Postiz, sets type to video, and schedules it for Sunday.

Reddit rules Perplexity Computer has to respect

Reddit enforces a few rules on every post. Postiz exposes them as settings, and Perplexity Computer applies them, but knowing them helps you phrase the request.

✓Every subreddit target needs its own title (max 300 characters) and a type: self, link, image, or video.
✓Many subreddits require a flair. Computer should check is_flair_required and fetch flair ids before posting.
✓Link posts need the url field; image and video posts need media uploaded through Postiz.
✓Subreddit names go without the r/ prefix in the settings, even though you can type r/ in your request.
✓Subreddit rules on self-promotion still apply; keep a human in the loop for community-sensitive posts.

Perplexity Computer and Reddit: frequently asked questions

How do I post to Reddit from Perplexity Computer?

Add Postiz as a custom remote connector in Perplexity settings using the MCP URL https://mcp.postiz.com/mcp-oauth-dynamic and OAuth, and connect your Reddit account in Postiz. Then ask Perplexity Computer to post to a subreddit; it fetches the subreddit's settings, picks the post type and flair, and schedules it through Postiz.

How does Perplexity Computer handle subreddit flairs?

Before posting, Computer asks Postiz for the Reddit channel's settings and the live flair list for the subreddit. If is_flair_required is true, it selects a flair id and name that matches your request and includes it in the post. You can also name the flair yourself in the prompt.

Can Perplexity Computer post to several subreddits at once?

Yes. One Postiz Reddit post can hold an array of subreddit targets, each with its own title, type, URL, and flair. Ask Computer to share the same content to r/A and r/B with different titles and it builds the array, so each community gets a post tuned to its rules.

Does posting to Reddit from Computer need a Reddit or Postiz API key?

No Reddit API key: you connect Reddit inside Postiz once with Reddit's own login. With the MCP connector, Perplexity signs in to Postiz over OAuth, so no Postiz API key is required either. Only the alternative CLI skill path uses POSTIZ_API_KEY in Computer's sandbox.

Can Perplexity Computer run a recurring Reddit posting routine?

Yes, through Scheduled Tasks in Computer, which run in Perplexity's cloud on a cadence you confirm, at most once an hour. For example: every Friday, find our best blog post of the week and schedule it to r/programming with the right flair. Review what it queues; subreddit rules on self-promotion still apply.
