A new vision for chess.
Scan a handwritten scoresheet, snap a photo of a board, or record a game live with your camera. KnightVision turns the chess you play over the board into games you can review and learn from.
Board scan
Point your camera at a real board.
Works with the standard tournament boards and pieces you already play on — no special mat or electronic board needed.
Corner lock
It finds the board and locks on.
KnightVision maps all 64 squares from the board's four corners. If a corner is off, nudge it into place.
Every piece
Then reads the position.
Fix any square in the editor, then analyze the position, save it, or play on from there.
Capture
Every game you play, captured.
On paper, on the board, or in a book — get it into KnightVision in a few taps, and keep every game in one library.
Scoresheet scan
Snap your scoresheet. Get a game you can replay.
KnightVision reads each handwritten move, replays the game to check every move is legal, and stops at anything it can't make out so you can fix it on the board. Then save the game or download the PGN.
- Algebraic, in 7 languages
- Figurine
- Descriptive
- Coordinate
Live recording
Record a game as you play it.
Set your camera over the board and KnightVision tracks each move as it's made — with undo and re-sync if anything slips. Turn on spoken moves to hear every move called out.
Board & diagram scan
Turn any position into one you can study.
Photograph a real board, or a diagram in a book or on a screen. Correct any square in the editor, then analyze it, save it with notes, or play on from there.
Import from Chess.com and Lichess
Bring your online games in by username.
Enter moves by hand
Play a game through on a digital board and copy the PGN.
One library for every game
Filter by where a game came from, replay it, export the PGN.
Review
Find the moment the game turned.
Run a full engine review on any game. Every move gets a label, both sides get an accuracy score, and the evaluation graph shows exactly where the game swung.
