Then the analysis: where the game turned
This is the free review of the example scoresheet above, exactly as the scanner shows it once the moves are checked. Every game you scan gets the same: Stockfish runs in your browser and costs no credits.

Free, no sign-in: the review runs in your browser.
Accuracy and every mark
Each side's accuracy, with every inaccuracy (?!), mistake (?) and blunder (??) marked in the move list.
The turning points, and why
The moves where the game swung, each with a sentence that says what went wrong. In this game, Black could have won the bishop on f4 for a pawn two moves running and let it go both times.
The AI coach, in plain words
Ask the coach about the turning points: what happened, what your opponent could do and what to play instead, written only from the engine's facts. A free account gets one explanation a day (Pro 5, Pro+ 15), then 1 credit per game.
Your misses become practice
Missed tactics turn into practice cards from your own games; this one has 2. 15 cards a day are free with an account, unlimited on Pro.
And every game you scan adds up
Saved to your games
Kept with its photo in your games library, ready to export as PGN.
Digitize your gamesYour insights profile
Your analyzed games build a profile of your play: accuracy over time, phases, mistake types (the full profile is Pro).
Prepare for the next opponentPro
Opening repertoires that show where a game left your preparation, and scouting of an opponent's online games.
Scan, check, analyze
From a photo to a game you can study, in three steps.
Scan the image
Drop in a screenshot, a diagram or a photo of a board, or the pages of one game. A board costs 1 credit and a scoresheet scan 2, however many pages the game has.
Check it beside the original
Every move is checked against the rules and shown next to your photo, so you can compare and fix anything that differs. Corrections are free.

See the accuracy test
- moves read right on a real handwritten scoresheet: a tidy 1973 Berlin tournament sheet in German notation
- 43/45
- moves invented: we gave it 2 blank scoresheets and it read no moves from them
- 0
The test had 5 sheets: 1 real handwritten scoresheet, 2 printed test sheets and 2 blank ones. On the 3 with moves, it read 141 of 143 right.
A small test, not a guarantee: always compare the moves with your sheet.
A whole round of scoresheets?
Group the pages by game, add a pairing list and prepare a round for checking and PGN export. Keep individual game scans and tournament work separate.
Free for a club of up to 10 players; the club's own Pro+ lifts the limits (a personal plan doesn't cover a club).

Questions about ScanChess
Something else? The people who build ScanChess answer the support inbox themselves: support@scanchess.com
All questionsIs ScanChess free?
Signing up gives 10 free credits, enough for up to 10 board images or 5 scoresheet scans, with no card required. A board costs 1 credit and a scoresheet scan 2, however many pages the game has. The free tools need no account; reading a photo of a real board in the best move finder and asking for an AI explanation need a free account.
What do I get after scanning?
The game is saved to your games library with its photo. Stockfish analysis is free and shows each side's accuracy and the turning points, and the AI coach explains them: one game a day free (Pro 5, Pro+ 15), then 1 credit. Missed tactics become daily practice (15 a day free), and your analyzed games build an insights profile. Pro adds opening repertoires, opponent scouting and event reports; a club keeps up to 10 players for free, and Pro+ lifts the club limits.
Can it read a handwritten scoresheet?
Yes. Upload the pages of one game in order and the moves are read, checked against the rules and shown beside the original, so a doubtful move can be fixed before you export the PGN. It reads algebraic notation; descriptive notation such as P-K4 is not converted.
Which board images can I use?
A screenshot of an online game, a diagram from a book or a clear top-down photo of a real board. You get an editable FEN and choose the side to move; angled photos and carved 3D pieces may need a square or two corrected.
Why not just type the game into Lichess or Chess.com?
Both import a PGN, but someone has to type it first, and a single typo stops the import. ScanChess turns the photo into that PGN, checks that every move is legal, and the result imports into Lichess, Chess.com or ChessBase.
