This is cool. One thing I keep hoping either exists now or will soon is the ability to take a photo of an actual board position and get a FEN string out (or just directly send it to Stockfish and get an evaluation). It'd be really helpful to quickly analyze positions when I'm trying to help my kids out, cos we don't generally keep notation and I'm not always confident that my advice on a position is blunder-free.
I think you'll be pleasantly surprised, this is a thing!! I thought about making it but quickly decided computer vision wasn't up to the task yet. It seems I was horribly wrong: https://github.com/maciejczyzewski/neural-chessboard
Haven't tried it myself but it looks amazing
