LibreChess · Chess, explained simply

Review a game and find where it changed

Paste a PGN or open a game from the local archive. A quick Stockfish review selects up to three decisions to inspect, shows a stronger continuation where available, and lets you replay a move from the original position.

Move grades, accuracy, the evaluation graph, and the full move list remain available in the detailed section. Analysis runs on the device with short searches, so the results are useful review prompts rather than exhaustive engine proof.

Review a game privately in your browser — no account required.
