A multi-agent AI game running inside Reddit

Slop-Cops is a small web game that runs directly inside a Reddit post. A player enters a project idea or a URL, then five AI characters debate whether the idea is valid and how much it feels like low-effort AI output. The characters include a grammar checker, a suspicious bug hunter, a retro-style chief, a rookie, and a pessimistic senior engineer.

The app is built on Reddit’s Devvit platform. Its screen uses React inside an iframe, talks to a Hono server on Devvit, and stores state in Redis. Lite creates the AI character responses.

A live test version is available in r/slopcops.
