Post-game
questions.

  1. Chess.com and Lichess. You can also drop in a PGN, a FEN, or a link. Your analysis is built from real games, not demo positions.

  2. No. Games are reviewed right in your browser, and premium adds a deeper cloud engine pass for when you want Stockfish to dig further.

  3. Your own games. Every puzzle is a position you actually reached, themed to the weakness you're working on, and checked move by move.

  4. We compare how often you make each mistake to how often players at your level make it, then map that gap onto rating points. So you see what each leak really costs.

  5. Yes. Delete your account whenever you like and every game, analysis and file tied to it is wiped for good.

  6. Chesslark is in early access and free to start. Deeper cloud analysis and higher limits come with premium as we open more seats.
