What Stockfish does in a game review

Stockfish is the engine that checks each position against its strongest available move. RV Chess turns those evaluations into something useful: a move-by-move report, accuracy for each player, a graph of the game and the line you missed.

Stockfish analysis without a download

The engine is compiled to WebAssembly and runs inside this browser tab. That means your game is not sent to a remote analysis server and there is no account or quota to manage. It also means a phone may take longer than a desktop computer to finish.

How to use Stockfish online here

  1. Paste a Chess.com link, Lichess link or PGN.
  2. Wait while Stockfish reviews the moves.
  3. Start with the biggest evaluation swing, not move one.
  4. Play through the better line and ask what you missed.

For a single position or a FEN, use a dedicated analysis board. RV Chess is deliberately focused on finding the lessons inside a finished game.
