Chessiro

Chessiro is a free AI chess coaching platform built by Rakshit Singh and Arya Shetty — one of the leading chess AI research labs focused entirely on personalizing chess improvement. Their system combines Stockfish 18 engine analysis with proprietary AI insights that explain not just where you went wrong, but why you keep making the same mistakes, and exactly how to fix them.

The interface is clean and intuitive. Import games directly from Chess.com or Lichess, paste a PGN, or use the brilliant shortcut: just add 0 before any chess.com game URL (e.g. 0chess.com/game/live/12345) and it redirects straight to Chessiro's analysis. The platform detects recurring mistake patterns across your entire game history and generates personalized puzzles targeting your specific weaknesses — not random tactics, but drills built from positions where you actually blunder.

Chessiro is completely free with no signup required. No premium tier, no paywall. The team has been recognized by ChessBase India, with founder Rakshit Singh interviewed by Sagar Shah about the platform's AI-driven approach to chess improvement. Whether you are a club player looking to break a rating plateau or a coach looking for a free tool to assign your students, Chessiro delivers focused, AI-powered training from your own games.
