Try Playtest Lens

Game UX triage + playtest planning

Upload a screenshot, video, prototype, HUD, menu, onboarding flow, or game moment. Playtest Lens gives you a short, practical read on what players may misunderstand, who is most likely to struggle, what to watch for in playtesting, and the smallest useful fixes to try next.

Use this GPT for review, playtest planning, ideas, and inspiration only. A GPT can’t replace real playtesting or user research, because real people do unexpected things. Players bring different habits, expectations, skill levels, and contexts. Use Playtest Lens to focus what to test — then follow up with actual players.

What it helps you figure out

Playtest Lens is designed for indie devs, researchers, designers, educators, and teams who want a fast, practical way to move from screen critique to playtest plan. Use it for works in progress, prototypes, current games, or interactive products you want to learn from.

Onboarding & First Use

Whether first-time players know what to do, where to look, and how to start.

Playtest Planning

What to test, who to test with, what tasks to give, and what behaviors to watch for.

Smallest Useful Fixes

What to adjust first without over-fixing the game or flattening the intended experience.
