BlunderLens
Find the 3 chess mistakes you keep repeating, free
Stuck at the same rating? Enter your Chess.com username. Stockfish checks your recent games in your browser and ranks the 3 mistakes you repeat most (blunders by phase, missed chances, thrown wins, time trouble), with positions, fixes and drills. Free.
Hey Product Hunt 👋 I'm launching BlunderLens, a free tool for club chess players who keep losing the same way.
Most game review tools look at one game at a time. BlunderLens looks across your recent Chess.com games and asks what keeps happening: Do you blunder mostly in the middlegame? Miss your opponent's blunders? Let winning positions slip? Lose on the clock? Score badly with one opening?
Not ready to type your username? There's a sample report on the page (real games of a public account) so you can see exactly what you get first.
Stockfish 17 runs in your browser, so there's no signup and the report is free. If you want more, there's a $7/month daily training plan built from your own games. It's early access and I deliver the first plans myself within 48h.
It's Chess.com-only for now (not affiliated with them); Lichess is next if people want it. I'd love blunt feedback: did your top 3 feel accurate?
