Type in your Lichess and/or Chess.com username and it sorts your games into six lists: your cleanest wins, the highest-rated players you beat, your biggest rating upsets, games where the evaluation swung back and forth, games you were losing but still won, and long endgames you ground out. Each game comes with a board you can play through. It all runs in your browser, and nothing is uploaded.
This is a work in progress, so expect some rough edges. Feedback is welcome.

Fill in either or both. Games from both sites are pooled into one report. Chess.com games have no stored analysis, so they are all evaluated in your browser (slower).
Lichess limits anonymous downloads to ~20 games/second; a free token raises that to 30/s (60/s for your own games).
Open the Lichess token page ↗. The description is already filled in.
You don't need to tick any of the permission checkboxes (none are required): just scroll to the bottom and click Create, then copy the token it shows (it starts with lip_) and paste it in the box above.
It stays in your browser and is used only to talk to Lichess.
Games you have already analysed on Lichess are scored right away. For the rest, Stockfish runs in your browser, and you get a time estimate before it starts.
