DeepChess turns raw Stockfish 18 engine data into plain-language coach explanations you can actually learn from. Paste any PGN or game link from lichess or chess.com โ€” our AI tells you exactly what went wrong with every move, not just "+1.45, Nf3 is best."

Every position is evaluated at tournament depth with MultiPV. The static engine classifies piece safety (safe, loose, hanging, pinned) and detects forks, skewers, and mate threats before the LLM touches anything โ€” so explanations are grounded in verified data, never hallucinated.

Built for players who are tired of staring at engine lines. One free analysis per day, premium plans for unlimited auto-analysis with accuracy percentages and tier badges.

Questions & Answers

As answered by people managing ChessDB and DeepChess.dev.

What makes your product unique?

DeepChess.dev's answer:

DeepChess uses an advanced static-analysis system which can extract hallucination-free features from a position before AI steps in.

Which are the primary technologies used for building your product?

DeepChess.dev's answer:

Stockfish 18 and Deepseek V4 Pro

How would you describe the primary audience of your product?

DeepChess.dev's answer:

Amateur and intermediate chess players (800โ€“1800 ELO) who play online on lichess or chess.com and want to improve, but find raw engine evaluations useless. They want to understand why a move was bad, not just see a number. Think: club players, self-taught improvers, and casual tournament players who can't afford a private coach but want coach-level feedback.

Why should a person choose your product over its competitors?

DeepChess.dev's answer:

Engines can tell you the best move. Only DeepChess tells you why yours was wrong โ€” in plain English, not engine numbers.
