Build your own repertoire. Study your own way.

Qxf7 is a serious study tool for tournament players: build and drill opening repertoires with spaced repetition, keep your games organized, and turn your own material into training. No courses. No content to buy. Your preparation.

Advanced Repertoire Building

Specify moves to train, moves to avoid, and moves that are just informational. Fully annotate your repertoire. Consult statistics filterable by time control and rating. Analyze with Stockfish.Qxf7 automatically detects transpositions. Build your lines move by move, or import them from PGN.

Build Understanding, Not Just Memory

Drill your repertoire with spaced repetition. Moves you know stay out of your way; moves you miss come back until they stick. Analyze and annotate your repertoire after training a line so future training gives you feedback in your own words.

Your games, organized and analyzed

Import games from Lichess, chess.com, or PGN files. Annotate with text and the full set of standard annotation symbols, analyze with an engine, color code your moves to easily see what you were thinking during the game vs what you analyzed afterwards. And see your coach's annotations in a different color.

Puzzles from your own material

Carve training positions out of your own games and books. Organize puzzles into chapters, set difficulty, and track your attempts over time.

For Coaches and Students

Coaches can leave comments on a student's games, create exercises for them, and participate in live sessions where students and coaches can interact in real-time. Student's can control their coach's level of access.
