Teardown

Write your own product teardown before the AI reveals its take.

Teardown helps you practice product sense on any product or company page. Click the extension on any product page. Teardown confirms what it found, then asks five questions: who it's built for, what job it's hired to do, why it beats the alternative, its biggest weak point, and what metric it would move. Write your own answer to each question first, then reveal an AI-generated perspective on the same question. Finish all five to see a summary with a one-time score reflecting how specific and grounded your answers were. This is a practice tool, not a grading tool. The goal is sharper product instincts, built for PM candidates, product builders, and anyone who wants to train their read on real products instead of just reading someone else's teardown. Bring your own Claude API key (BYOK). No account, no backend server, no data collection. Your key is used only to connect directly to Anthropic's API. Free and open source.
