DESIGNED FOR LEARNING
Knight Rise is built for review, training, and curiosity. Using an engine during a live rated game is cheating on every platform — Knight Rise asks you to confirm this on first launch and disables all analysis during live Lichess games. Every engine recommendation comes with a written explanation.

MULTI-LANGUAGE
Full English, Spanish, and French — lessons, coach text, and review verdicts included. Switch instantly from Settings.

PRIVATE BY DESIGN
The engine, vision pipeline, puzzles, achievements, and game history all live on your device. Nothing is uploaded; there are no ads and no analytics. Connecting a Lichess account is optional — games you play there live on your own Lichess account under Lichess's terms, and you can unlink anytime.
