Field notes
The review accepts PGN text or files, and username lookup requests recent public games from Lichess or Chess.com. Its example uses a board and replayable lines to show why an alternative move matters, including a forced mate in two. The site says its free analysis runs in the browser and sends no game upload; plain-language Coach notes are reserved for an optional Pro plan.
