What it does
Everything in the Analysis Board
Up to 5 best-move arrows
Stockfish's top candidate moves drawn straight on the board, ranked by strength — so you see the whole plan, not just one answer.
Live evaluation bar
A running eval bar shows who's better and by how much, updating as you step through the game. Spot the exact move it turned.
Full move navigation
Step forward and back with the arrow keys or click any move in the list. Branch off into your own lines, then snap back to the game.
Scan a board from an image
Got a position as a screenshot or photo? The built-in image-to-FEN scanner reads the board and loads it — no manual piece placement.
Import PGN or FEN
Paste a PGN from your Chess.com or Lichess history, or a FEN of any single position, and start analyzing in one click.
