ChessSolve

Real-time chess analysis

Understand every move as you play. ChessSolve overlays Stockfish analysis directly on your Chess.com and Lichess board — no tab-switching, no copy-pasting FENs, no extra windows. Built to help you learn faster and review deeper.

LIVE ANALYSIS Best-move arrows (up to 4 candidates on Premium) appear the moment it's your turn. Each move — yours and your opponent's — is rated in real time: brilliant, great, good, inaccuracy, mistake, blunder. A live evaluation bar shows who's ahead and by how much.

GAME REVIEW Step through any game move by move with full Stockfish evaluation to pinpoint where the game turned — and where you found the best move.
