e4Coach
Personalized chess coaching, powered by AI.
The Problem
Most chess analysis tools help players with single game analysis at a time. A single-game review tells you what went wrong in that game but it does not provide you a holistic picture of what are your problem areas beyond that single game.
The Approach
e4coach reviews a batch of your games together, groups the mistakes, and shows the weakness patterns costing you the most rating — so you train the root cause, not one-off blunders. e4Coach uses Stockfish combined with AI (Gemini) to analyze your games to identify repetitive weakness patterns and mistakes to help you become a better player faster by overcoming those problems.
