ChessyAI Chess Coach appHow the report works
Enter your Chess.com or Lichess username and choose the site. The tool loads your last 25 to 50 games from the public Chess.com or Lichess API and runs Stockfish over them in your own browser. Nothing is installed and you don't need an account. Analysis takes a little while because every move in every game is checked. On a computer it usually finishes in about a minute; on a phone it can take a little longer, so leave the page open.
When it's done, you get four things:
- Your Rating DNA, a radar chart with six areas of your game.
- Your three biggest weaknesses, ranked by how often they cost you.
- Your best and worst time of day to play.
- A shareable image card with the summary.
Reading your Rating DNA
The radar chart scores six parts of your game against each other. A spike shows a strength and a dent shows a leak. The scores are relative to you, so they show where your points are going, not how you compare with a grandmaster.
| Area | What it looks at |
|---|---|
| Tactics | How often you hang pieces, miss tactics or miss free material your opponent leaves. |
| Openings | How your position looks coming out of the opening, and which openings score worst for you. |
| Endgame | How well you play once most pieces are off the board, including won endgames that slip away. |
| Time management | Losses on time, and mistakes made when your clock is low. |
| Conversion | How often you win games where you got a clear advantage. |
| Resilience | How often you save or turn around games where you were worse. |
Time management needs clock data. Most online games include it, but if yours don't, that area is shown with less confidence. With fewer than about 25 games, any area can be noisy, so take a small sample as a hint, not a verdict.
Your top three weaknesses
The three weaknesses are the specific problems that cost you the most across these games, each with a short explanation and how often it happened. Typical examples are leaving pieces undefended, missing your opponent's threat, giving away a winning position, or spending too long early and rushing later.
Start with number one. It's tempting to work on all three, but fixing one habit properly moves your rating more than half-fixing three. Give it two or three weeks, then run the report again and see whether it has dropped down the list.
Best and worst time of day
The report also groups your results by the hour you played. If one window is clearly worse, often late at night, that's a free fix: just stop playing rated games then. For the full breakdown by hour and weekday, plus your win rate after a loss, use the Tilt & Bad Hours Detector.
How to fix the most common weaknesses
Tactics
Do 15 to 20 minutes of puzzles a day and add a blunder check before every move: what does their last move attack, and is everything of mine still protected after my move? Our guide on how to stop hanging pieces explains how.
Openings
Pick one opening as White and one reply to each of 1.e4 and 1.d4, and learn the main ideas and traps. You don't need deep theory. See the best openings for beginners.
Endgame and conversion
When you're ahead, trade pieces, keep your king safe and stop looking for brilliancies. Learn the basic king and pawn endings, because many won games are lost in them.
Time management
Play a slightly longer time control, play your opening moves quickly, and save your thinking time for captures, checks and sharp moments.
Resilience
When you're worse, don't resign early and don't panic. Make the position as complicated as you safely can, and keep making your opponent find good moves.
Going deeper
The report shows patterns. To see the exact moves behind them, open a game in the free game review, then replay the key position in the analysis board. If you'd rather hear your weaknesses as jokes, Roast My Chess uses the same kind of stats.
For a method you can repeat by hand, read how to find your chess weaknesses. If you've been stuck at the same number for months, how to break a rating plateau is the next step, and how to get better at chess covers the bigger picture. All guides are in the guides section.
Chessy — AI Chess Coach app keeps this report up to date as you play, builds puzzles from the positions where you went wrong and gives you a daily plan aimed at your top weakness.
