Chessglance reads chess positions from images and video

Field notes

For browser scans, a model downloaded once runs locally; the page says those images are not uploaded. It evaluates all 64 squares, applies chess-legality checks, and flags low-confidence squares for correction before FEN export or opening in Lichess. Results vary by evaluation set: the page reports 84.1% exact on 107 1920s-book boards and 65% on 844 held-out diagrams from 11 books.
