Rankfile - Chess Scanner

Rankfile turns a photo of a chess diagram into a position you can work with. Point the camera at a book, magazine, PDF or screen; Rankfile finds the diagram, reads the pieces, and gives you an editable board. Copy FEN, share it, or open the position in Lichess analysis.

Everything runs on your iPhone. No account, no upload, no subscription.

SCAN • Photograph a page or pick photos from your library, up to 20 at a time • Several diagrams on one page are found and read together • Whose move? Rankfile reads captions such as "White to play", move numbers and W/B markers next to the board

CHECK AND FIX • Squares the model is unsure about are marked; tap one to see its alternative and confirm with one tap • Tap any square to change the piece on an on-screen board • Impossible positions (missing king, pawn on the back rank, both kings in check) are flagged.

BOOKS • A copy of Capablanca’s Chess Fundamentals is included so you can try the reader immediately • Import your own chess PDF and read it page by page • Diagrams on the page are detected as you read; tap one to open it on the board

LIBRARY • Save positions with a title and note, search by text or FEN, and revisit them later • Print a diagram or share several as a PDF

ANALYSE AND SHARE • Copy FEN or share it to any app • Open the position in Lichess analysis (in the browser)

Made for chess books, PDFs and screenshots: printed diagrams, digital boards, puzzle pages. Not for photographing a physical 3D board.

Privacy: photos and PDFs are processed on your device and never leave it. Rankfile does not collect any data.
