I built ChessAnalysis after spending too long reviewing my own games move by move. It runs Stockfish locally, so you can review unlimited games for free, and it explains the three moves that actually cost you the game instead of only showing a number. Happy to answer questions about the accuracy formula or how the browser engine works.
