Question 1

Is Chess Vision AI free to use?

Accepted Answer

Yes. Chess Vision AI is free and requires no account. You can analyze positions from a screenshot, FEN, or PGN right away.

Question 2

How does the screenshot chess analysis work?

Accepted Answer

Upload or paste a chess board screenshot from Chess.com, Lichess, YouTube, or a phone photo. AI vision reads the position and converts it to a FEN, then Stockfish 16 evaluates it and returns the best move and engine lines.

Question 3

Can I analyze a full game with a PGN?

Accepted Answer

Yes. Paste a full game's PGN and step through every move with persistent Stockfish analysis on each position, including an Auto Play mode that follows the engine's best line.

Question 4

Which chess engine does Chess Vision AI use?

Accepted Answer

It uses Stockfish 16 with adjustable search depth and multi-line (MultiPV) evaluation, so you can see the top engine moves and the evaluation for any position.
