Overview
Blunders.ai pulls your actual games from online chess platforms and turns your real mistakes into targeted training material. Instead of working through generic puzzle sets, you drill the exact positions where your own games fell apart — openings you misplay, endgames you blunder, tactical patterns you consistently miss. The AI coach analyzes your game history to identify recurring weaknesses and serves up puzzles calibrated to your current level and problem areas. You're not grinding through someone else's curriculum; you're fixing the specific holes in your own game. It's freemium, so you can connect your account and get a baseline read on your weaknesses without paying. The depth of coaching and puzzle volume presumably scales with a paid tier.
- Generate puzzles directly from your own game blunders and missed tactics
- Get AI coaching feedback tied to your personal game patterns, not generic advice
- Identify recurring weaknesses across your game history automatically
- Train on positions that match your actual playing style and rating range
- Connect existing online chess accounts to import game history
What stands out
- Training is grounded in your real games, which makes mistakes harder to ignore and easier to remember
- Cuts through the noise of generic puzzle books by targeting your actual weak spots
- Freemium entry point lets you evaluate usefulness before committing money
- Scales with how much you play — more games means more personalized data
Where it falls short
- Usefulness depends heavily on having an existing game history; new players with few games get less signal
- AI coaching quality is hard to evaluate without knowing the underlying model or how it handles complex positional errors
- Freemium limits are unspecified upfront, so it's unclear how much value you get before hitting a paywall
Who it's for
- Club and online players stuck at a rating plateau who want to know exactly why they keep losing
- Beginners who learn better from their own mistakes than from abstract exercises
- Competitive players who want structured post-game analysis without hiring a human coach
- Chess students who play regularly on Lichess or Chess.com and want their game history to do more work
