Generic puzzle apps show you random positions from master games. Chessdock shows you the exact positions where you went wrong. If you consistently miss knight forks in the middlegame, you'll get puzzles specifically about that.

It's personalized training based on your actual weaknesses, not someone else's.

We analyze each game with Stockfish, one of the world's strongest chess engines. When you make a move that loses material or gives your opponent a significant advantage, we capture that position and create a puzzle asking "what should you have played instead?"

You're literally replaying your mistakes with a second chance to find the right move.

We use evaluation changes to identify mistakes. If your move gives your opponent any advantage, we classify it as a mistake worth practicing.

We capture everything from minor inaccuracies to major blunders, so you can focus on the mistakes that matter most to your rating.

Game review shows you everything that happened in your game - every move, every alternative, the full picture. That's great for deep analysis, but it's not efficient when you just want to find and fix your mistakes. With game review, you have to click through each game manually and hunt for the moments that matter.

Chessdock does one thing really well: it finds all your mistakes across every game and turns them into practice puzzles. No clicking through moves, no searching - just ready-to-practice puzzles from the exact positions where you went wrong. It's like having someone watch all your games and automatically highlight the important moments for you to work on.

Not at all! Whether you're 800 or 2000 rated, you make mistakes worth practicing. Beginners often benefit even more because they have more obvious tactical oversights to fix.

If you're playing chess, Chessdock can help you improve.

Absolutely. As you work through puzzles from your own games, you'll start noticing recurring themes. Since every puzzle comes from a position you actually played, the patterns that emerge are your real weaknesses.

That awareness is powerful - once you know what to watch for, you can catch these mistakes before you make them.

Yes! Every time you play new games, we analyze them and create fresh puzzles. As you play at higher ratings or try different openings, your puzzle set evolves with you.

It's a living training tool that grows with your chess journey.

That's great awareness! But knowing you made a mistake is different from training your pattern recognition to avoid it next time. Solving the puzzle helps cement the correct pattern in your mind, so in future games you'll spot the tactic before you make the mistake.

No problem! Even 50-100 games gives you dozens of puzzles. And we'll keep creating new ones as you play.

Yes! Connect one or both platforms as you like.
