I built an alternative game analysis that runs entirely in your browser

Hi everyone,

I put together a free browser-based game analysis tool for chess.com players, no account, no install, no backend.

It pulls your games via the public chess.com API and uses Stockfish WebAssembly to analyse the most critical positions in each game (rather than every move, which would be too slow). From that it builds a profile of your weaknesses: which pieces trip you up most, which openings you consistently misplay, how your accuracy changes under time pressure, endgame performance by material type, and more.

It's aimed at beginners, but some insights could even be of use to coaches or advanced players.

Happy to answer questions about how it works. All feedback welcome!

Thank you for reading!
