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.

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

Stockfish 18 and Deepseek V4 Pro
DeepChess.dev's answer:
Amateur and intermediate chess players (800โ1800 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.
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.

Edit - I'll add a very complex idea: an AI-powered tool that analyzes a position as a person would, using natural language to explain positional and long-term ideas, not pointing out simple tactics. decodechess.com has tried this but it's not there yet. Source: over 2 years ago
It's not a free app, but they provide a demo that shows the main features: https://decodechess.com/. Source: over 3 years ago
Instead I'd play real people and use something like decodechess.com or just the analysis board. Source: over 3 years ago
You could try Decode Chess, that will analyse one game per day for free, and explains the effects of each move in a lot more detail than the chess.com game review. Source: over 3 years ago
A couple of sources I've found that is helpful are Learning Chess and Decode Chess, because they offer solid analysis and evaluations telling you why one move is better than the other, helping you understand the reason behind the moves. Source: over 3 years ago
