Ever seen an interesting chess position in a book, video, or article and wanted to study it? Our Position Reader lets you upload a screenshot or photo and get deep Stockfish analysis — no need to manually recreate the position piece by piece.
The Position Reader uses computer vision technology to detect each piece on the board, convert the position to FEN notation, and then run it through Stockfish 18 for analysis. It works with images from books, videos, articles, and completed games.
Converting a chess image to analysis involves three steps:
Step 1: Upload Your Image
Take a photo of a position from a book, video, or physical board. Upload it to our chess solver using the image upload button.
Step 2: Position Detection
Our computer vision system identifies the board boundaries, detects each square, and recognizes the pieces. It generates a FEN string representing the exact position.
Step 3: Stockfish Analysis
The detected position is loaded into Stockfish, which analyzes millions of possibilities per second to find the best move. You get the evaluation score, best continuation, and alternative moves.
Supported Image Sources
Our chess position scanner works with various image sources:
Online chess platforms: High accuracy detection from any board theme and piece set
Physical board photos: Photos of real chess boards (best results from directly above)
Chess books and magazines: Printed diagrams from chess publications
Video screenshots: Paused frames from chess streams or YouTube videos
Tips for Best Results
Do
Use screenshots rather than photos when possible
Crop the image to show just the chess board
Ensure all pieces are clearly visible
Use good lighting for physical board photos
Avoid
Blurry or low-resolution images
Extreme angles on physical boards
Partial board views (all 64 squares needed)
Images with overlays or annotations covering pieces
Alternative: Manual Position Setup
If the Position Reader isn't available or you want to use the free tier, you can set up positions manually:
FEN string: Copy the FEN from your chess platform (usually under "Share" or "Analysis board") and paste it into our chess solver
Drag and drop: Use the board editor to place pieces manually — clear the board and drag pieces to their positions
PGN import: Paste the full game notation to load and replay the game move by move in our analysis tool
When to Use Chess Image Analysis
The chess solver from image feature is useful in many situations:
Post-game review: Screenshot a critical position from your game and analyze it in depth
Learning from videos: Pause a chess stream, screenshot the position, and find the best move
Studying books: Photograph a diagram from a chess book and get engine analysis
OTB analysis: Take a photo of your over-the-board game position for post-game review

Position Reader - FAQ
Can I solve a chess position from a photo?
Yes! Upload a screenshot or photo of any chess board to our scanner. It uses computer vision to detect the position and converts it into a FEN string that Stockfish can analyze. The solver then finds the best move.
What images work with the Position Reader?
Our Position Reader works with screenshots from any chess book, video, or article. It also recognizes physical chess boards from photos, though digital screenshots produce the most accurate results.
How accurate is chess position detection from images?
Digital screenshots have 95%+ accuracy. Physical board photos depend on lighting, angle, and piece visibility. For best results, take photos from directly above with good lighting.
Is the Position Reader free?
The Position Reader is a Pro feature ($9.99/mo). You can use the free chess solver by manually setting up positions on the board or pasting FEN strings.
What is FEN notation?
FEN (Forsyth-Edwards Notation) describes a chess position as text. For example: 'rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq e3' represents the position after 1.e4. You can paste FEN into our solver instead of using images.
Can I scan a position from a chess book?
Yes! Take a clear photo of the chess diagram from the book. Our scanner will attempt to detect the position. For printed diagrams, results are good. For hand-drawn or small diagrams, manual FEN entry may be more reliable.
