A free program for Android, by Gerhard Roth.

ChessOcr is a free app that can recognize and translate all kinds of Chess Diagrams. It uses OCR technology to make the process of character recognition more efficient.

This app is a useful tool for anyone who wants to learn more about chess and has some experience playing the game. It can help you improve your game by analyzing your moves.

It works best for cameras that can autofocus. Make sure that there is proper lighting. When the light is too low or if you are using a camera that can’t autofocus, you may encounter some issues. When scanning, try to keep the page as flat as you can. Once the diagram has been successfully recognized, a green box will appear.
