Chessalyz

Chessalyz is an AI-powered chess analysis platform co-founded by FM Dalton Perrine and Varun Kumar. Instead of showing you what the engine thinks is best, Chessalyz identifies critical moments in your games and asks guided questions that help you understand your own decision-making process.

The platform automatically highlights positions that shaped the outcome of your game, then walks you through them with interactive prompts adapted to your skill level. The goal is teaching transferable patterns and strategic concepts — not memorizing engine lines you will never see again. It integrates with both Chess.com and Lichess, and supports manual PGN uploads.

Chessalyz also includes a flashcard system that converts critical positions from your games into spaced-repetition cards, so you can drill the patterns that matter most to your improvement. Full mobile browser support means you can review games and practice flashcards on the go.

Pricing starts free (5 analyses/month) with paid tiers at .99, .99, and /month for more analyses, faster processing, and expanded game storage. The co-founders also host the Chess Chatter podcast.
