ChessAnalysis sidesteps the rationing that defines mainstream game review. Instead of metering server side engine time, it compiles Stockfish to WebAssembly and runs the analysis on the user's device. That single architectural choice removes the daily review caps that free Chess.com accounts hit, and it keeps game data local—no upload, no account, no stored PGNs. The product is not a chess platform; it is a review layer that pulls public games from Chess.com and Lichess via their APIs and returns a structured report in seconds.
