Hey PH! I'm Shane, and I built D4 Chess Club because every chess app I tried just told me what the best move was, without explaining why my move was wrong. That doesn't build pattern recognition. It builds dependency. D4 Chess Club does things differently: Play vs computer - adjustable from 1000 to 3200 Elo Stockfish analysis - every move classified: excellent, inaccuracy, mistake, blunder Real-time threat overlay - see attacks and hanging pieces as you step through moves AI Socratic Coach - asks targeted questions about your mistakes instead of just handing you the answer Tactical drills - spaced repetition built from the patterns you miss most Free forever for core features. Premium ($5.99/mo) unlocks the AI coach, unlimited puzzles, and the full course library. I'd love feedback from the chess players here. What would make this your go-to training tool? https://d4chess.club

D4Chess.Club — AI chess coach that finds your mistake patterns, not just your blunders

Hey Product Hunt! Shane here, solo founder of D4Chess.Club.

I built this because I kept hitting the same wall every club-level chess player hits: I knew I was making mistakes, but no tool could tell me which mistakes I kept repeating or why. Chess.com has 200M users and endless puzzles. Lichess is free and incredible. Neither one sits down with you after a game and says "here's your pattern, here's how to fix it."

So I built that tool. D4Chess.Club analyzes your game history, surfaces your recurring error patterns, and coaches you through them with AI-powered walkthroughs Socratic-style, not just "the computer plays Nf6 here."

A few things I'd genuinely love feedback on:
