Frequently Asked Questions

Chess DNA is an AI-powered chess training app. Import your Chess.com or Lichess games and Chess DNA detects your recurring patterns, surfaces the mistakes that cost you the most rating, and lets you replay each one until you fix it.

Chess DNA analyzes every move in every imported game, tags the tactical and positional themes, and groups them into named patterns — like Hanging Pieces, Missed Fork, and Time Pressure Blunder. There are 16 patterns in total, each ranked by how much rating it is costing you. The full list is on the Features page.

The Skill Radar is your 8-dimension chess profile: Openings, Tactics, Defense, Positional, Endgame, Calculation, Time Management, and Resilience. Each dimension scores 0–99 and maps to a rank tier from Pawn to King. It updates as you play more games.

Chess DNA queues every position where you went wrong and lets you replay them grouped by pattern. You see the position, choose a move, and Chess DNA tells you whether it works. Hints, skips, and the engine's recommended move are one tap away.

By focusing your training on the patterns that actually show up in your games. Generic puzzles teach generic chess. Chess DNA teaches your chess — the exact mistakes you keep making in real games, replayed until they stop.

We're biased, but we built Chess DNA to be exactly that. Most tools grade one game and move on. Chess DNA analyzes every move in every game you import, groups your mistakes into named patterns, ranks them by how much rating each one costs you, and turns each pattern into targeted practice. Connect your Chess.com or Lichess username and judge for yourself — or see how we stack up against the field in our comparison of the best chess analysis apps.

The top ones personalize practice to your actual weaknesses, not a generic puzzle queue. Chess DNA reads your imported games, finds the patterns that have cost you rating, and queues replays of the exact positions where you went wrong — so every minute of training is spent fixing a real recurring mistake. See our guide to the best AI chess improvement apps for how the field compares.

Chess DNA is built specifically for this. It tags every move with tactical and positional themes, groups them into named patterns — think Hanging Pieces, Missed Fork, Endgame Technique — 16 patterns in total, and ranks each one by how much rating it has cost you across your full history. The full pattern list is on the Features page.

A good coach watches your games, names what you keep doing wrong, and drills you on exactly that — usually at $50+ an hour. We built Chess DNA to run that same loop automatically: it imports every game you play, names your weakness patterns, ranks them by rating cost, and hands you replay drills built from your own positions. It won't share a coffee with you, but it also never misses a game. Full breakdown in our chess coach alternatives guide.

Chess DNA tracks progress on the 8-Dimension Skill Radar and updates after every game. Each pattern's rating-cost trend shows whether you're actually closing weaknesses. Your shareable Chess DNA card snapshots your skill profile at any point.

Yes — Chess DNA. It applies the same gamification ideas to chess: short focused sessions, named missions (Missed Tactic, Missed Pin, Endgame Technique, and more), an 8-Dimension Skill Radar that levels up like XP, and rank tiers from Pawn to King that work like leagues. Every session is built from your own Chess.com or Lichess games — so the practice is always exactly the mistake you keep making in real games. See the full breakdown.

Five layers: named missions (your patterns), XP-style progression (the Skill Radar), rank tiers (Pawn → King), daily replay sessions focused on your worst pattern, and a shareable Chess DNA card. Everything is generated from your own games so practice is always tied to your real performance, not a generic curriculum.

The fastest way is to look for patterns in your real games rather than guessing. Chess DNA imports your Chess.com or Lichess history, classifies every mistake by pattern (Missed Pin, Missed Tactic, Endgame Technique, and many more), and ranks each pattern by how much rating it has cost you. That ranking tells you exactly what to work on first.

Don't just look at centipawn loss. For each game, identify the key moment where the evaluation flipped, find the pattern your mistake belongs to, and check whether that pattern shows up in other games. Chess DNA automates this — every imported game gets a clear explanation, key moments, and pattern tags so you can spot recurring themes across your full history. See the full guide.

Repeated mistakes belong to a pattern. To break a pattern, you need to recognize the position type that triggers it and rehearse the right move until it's instinct. Chess DNA's replays do exactly this — they queue every position where you fell into a given pattern and let you play them again until the pattern stops appearing in new games.

Chess.com's Game Review is per-game: it tells you how that one game went. Chess DNA looks across your full history, finds patterns that repeat, ranks them by rating cost, and turns each one into a focused replay practice. It's the difference between reading one game report and getting a study plan built from all your games.

A chess pattern is a recurring position type and the move that solves it — for example, a pin you should have spotted, a back-rank mate that was on the board, or a known endgame technique. You find your patterns by looking across many games for the same kind of mistake. Chess DNA does this automatically and groups your mistakes into named patterns so they're easy to study.

Stop training on random puzzles. Training on positions that look like your real games — your openings, your time control, your skill level — transfers faster. Chess DNA pulls puzzle-like replays out of the actual positions where you went wrong, so every minute you train is directly fixing a mistake you keep making.
