About this app

Snap a photo. Get a PGN. That's it.

ChessScribe turns the handwritten scoresheet from your over-the-board (OTB) game into a clean, validated PGN — no more retyping moves one by one.

Just played a tournament game? Instead of squinting at your score sheet and typing it in by hand, take one picture. ChessScribe reads the moves with AI, checks every one against the rules of chess, and hands you a PGN that's ready for Lichess, chess.com, or your favorite engine.

SNAP → CHECK → EXPORT
1. Snap your scoresheet (or pick a photo from your gallery).
2. AI transcribes the notation and validates every move.
3. Fix anything unclear on a real chessboard, then export or share.

ACCURATE — NOT A GUESS
Handwriting is messy. Notation has mistakes. ChessScribe doesn't just "read and hope" — it pairs AI handwriting recognition with a real chess rules engine, so what you get is always a legal, playable game. When a move is illegible or ambiguous, the app flags it and shows you exactly what to confirm, right on the board. It even tells you how it read each tricky move.

WHAT YOU GET
• Scan from your camera or photo library
• AI move recognition + rule-based legality checking
• Edit on an interactive board — tap a move to jump there, then play the correct one to overwrite or insert
• Automatic result detection — checkmate, stalemate, draw
• Editable game info — players, event, date, result
• Export to a .pgn file or share it anywhere
• Saved games stay on your device

MADE FOR CHESS PLAYERS
• Tournament and club players digitizing their OTB games
• Coaches and students reviewing right after the round
• Anyone with a drawer full of paper scoresheets

PRIVATE BY DESIGN
No account. No sign-up. No ads. Your saved games and scoresheet photos stay on your phone — the only thing that leaves your device is the image you scan, used solely to read the moves.

Your games belong in a database, not a drawer. Snap, check, export — and never retype a scoresheet again.
