Import games from PGN

Reviewing games that were not played online

Club and tournament games are the ones most worth reviewing and the hardest to get into an engine. If you keep a scoresheet, most players end up typing the moves into an analysis board once and then never looking at the game again. Importing the PGN instead puts the game into the same review the online games get: every move graded, the turning points marked, and the mistakes counted alongside the rest of your play.

Where to get a PGN

Most sources will give you one. Chess.com and Lichess both offer a download on any finished game, and if you connect a handle those arrive automatically. For over-the-board games, DGT boards and most tournament pairing software export PGN directly, and apps that digitise a scoresheet will too. A file containing several games is fine — each one is listed separately so you can choose which side you played before importing.

What happens to the file

Nothing is uploaded. Parsing happens in the page, the games are written to storage in this browser, and the analysis runs on a Stockfish build that also executes locally. That means imported games stay on the device you imported them on — useful for privacy, worth knowing if you clear site data or expect them to appear on your phone.

Picking the right side

The review is written from one player’s point of view, so which colour you played changes every judgement on the page. The side is guessed from the PGN’s player tags where it can be, but the guess is shown rather than assumed — check it before importing, particularly for games exported by someone else or copied from a database.
