PLAYTEST
Built at Gemini 4 Argon SF Hackathon · Oct 25, 2026 · San Francisco, CA

Playtest is an AI agent for game testing, powered by Gemini Argon. Give it a playable build and a testing goal, and it plays your game to find bugs, whether it's a character getting stuck or a quest that won't progress. As it plays, it learns from what's happening on screen and adjusts its actions to test different parts of the game. It can catch bugs developers might miss and show exactly what happened so they can reproduce and fix them. Playtest helps developers spend less time searching for bugs and more time building their games.
