A Chessiro alternative built on your repeated mistakes
Chessiro reviews your games one by one with Stockfish, and an AI coach explains each mistake and answers your questions. Chess X-Ray answers a different question: across all your recent games, in which positions do you keep playing the same losing move? Give your chess.com or Lichess username and you replay those exact positions as lessons.

What Chessiro does well
Chessiro gives a complete review of every game, with Stockfish running in your browser: a label for each move, an accuracy score, an evaluation graph and the turning points. Its AI coach explains what each mistake missed in plain words, answers follow-up questions and can play out what-if lines. It also builds puzzles from the positions you got wrong, and has bots, an opening explorer and a glossary.
Where Chess X-Ray is different
A review looks at one game. The mistakes that cost you most are the ones you make again in the next game, and the one after. Chess X-Ray reads your recent games together, finds the positions you reach again and again, and the move you play there every time. Each lesson shows that move in red, lets you look for better, then gives the right line and the point to remember.
The result is short on purpose: 10 mistakes, ranked by what they cost you, rather than one review per game to read.
Which one should you choose?
- Choose Chessiro if you want to review each game right after you play it and ask a coach why a move was wrong.
- Choose Chess X-Ray if you want to know which mistakes you keep repeating across all your games, and to replay each one on your exact position until the right move comes without thinking. See how it works.
Frequently asked questions
What is the best alternative to Chessiro?
It depends on what you use it for. For reviewing one game, the Lichess analysis board and chess.com Game Review do the same job. For training on the mistakes you repeat across your games, Chess X-Ray finds those positions and turns each into a lesson.
Can I use Chessiro and Chess X-Ray together?
Yes. Many players review a game right after playing it, then work on their recurring mistakes once a week. The two answer different questions.
Does Chess X-Ray work with Lichess like Chessiro?
Yes. Chess X-Ray reads chess.com and Lichess games from your username.
Do you need my chess.com or Lichess password?
No. Chess X-Ray reads your games through the public chess.com or Lichess API, using your username. We never ask for your password and never sign in to your account.
