TacticSnap: Chess Scanner

See a chess position worth exploring? TacticSnap turns a screenshot or photo into an interactive board in seconds.

Share an image with TacticSnap from Photos or another app, choose one from your library, or take a photo. The app finds the board, recognizes the pieces, and opens the position ready for analysis.

PRIVATE BY DESIGN
Recognition and engine analysis happen on your device. TacticSnap does not require an account, contains no ads, and does not upload your screenshots for processing.

Whether a tactic appears in a video, a lesson, a message, or a social post, TacticSnap gets you from screenshot to analysis with fewer steps.
