Solve once. Free for everyone, forever.
Every puzzle our engine solves is kept. When anyone uploads a puzzle we've seen before — the same daily, the same newspaper page — we serve the answer instantly, with no AI call and zero cost. The repository compounds: the more it's used, the faster and cheaper it gets.

How it works: each solved puzzle is keyed by a fingerprint of its grid and clues and stored in our shared repository. A re-upload that matches is answered from storage — never re-solved. Cost and time saved are conservative estimates ($0.10 and 18s per avoided solve); the real win grows with the most-shared puzzles (today's NYT, the popular dailies).
