Field notes
The homepage’s Queen’s Gambit Declined example identifies a diagram on page 37, asks about the g5 square, and then shows a Stockfish 18 suggestion. The page says Stockfish runs in the browser and that book files stay on the reader’s device, while numbers extracted from diagrams are sent for reading. It also describes previous/next diagram navigation and read-aloud using device voices.
