AI Chess Coach

An AI chess coach that explains your own games. Stockfish 19 finds the moments that decided the game, and the coach tells you in plain English what you missed and what to play instead. Then ask it anything about the position.

Chessiro Coach explaining a position: Black castles to safety, but White's space advantage and better coordination give a comfortable edge, with follow-up questions suggested
The coach explains the position, suggests follow-up questions, and answers anything you type about it.

What the AI coach does

It explains the why

Not just "blunder, -3.2". The coach tells you what threat you missed, which idea mattered in the position, and what the better move was trying to do.

Ask it anything about your position

"Why can't I take the pawn?" "What was my opponent's plan?" Ask in your own words and the coach answers about the exact position, with arrows drawn on the board.

Concepts, in your own game

Pins, weak squares, overloaded defenders, bad bishops. Terms stop being abstract when they're explained in a position you actually played.

Your mistakes become training

The coach tracks the mistakes you repeat across games and turns those positions into puzzles, so you practise the exact thing that keeps costing you.

AI chess coach vs a human coach

A good human coach is still the gold standard for a long-term plan. But lessons cost money and happen once a week, and most of what you need to learn is sitting in the games you played yesterday. That is where an AI coach helps.

Available after every game

Review a game the moment it ends, day or night, instead of saving questions for a weekly lesson.

Grounded in the engine

Every explanation starts from Stockfish 19's evaluation, so the move it recommends is the engine's best move.

Patient with every question

Ask the same basic question five ways. No question is too simple, and nobody is watching the clock.

For the longer take, read can an AI chess coach actually help you improve? and how the coach explains why a move was a mistake.

How does an AI chess coach work?

Stockfish 19 analyzes your game first, so the coach always knows the best move and how much each mistake cost. The coach then turns that into a plain-English explanation of the position: the threat you missed, the idea behind the better move, and what to watch for next time. You can ask follow-up questions and it answers about the exact position on the board.

How accurate is the AI chess coach?

The moves it recommends come from Stockfish, so those are engine-accurate. The explanations are right most of the time, and strongest on tactics, piece safety and common strategic ideas. In very deep strategic positions or rare endgames it can oversimplify, which is why it always shows you the engine line alongside the explanation.

Can it review my Chess.com and Lichess games?

Yes. Import your recent games from Chess.com or Lichess, or paste any PGN, including over-the-board games you typed up. The coach works on any game once the engine review has run.

Which languages does the coach speak?

24, including English, Spanish, Portuguese, French, German, Italian, Russian, Turkish, Polish, Hindi, Arabic, Japanese, Korean and Chinese. Explanations can also be read aloud.

Does an AI chess coach replace a human coach?

No. A strong human coach who knows you and builds a plan over months is hard to beat. What the AI coach gives you is an explanation after every game, at any hour, for free or a fraction of what lessons cost. Many players use both: the AI coach for everyday review, a human coach for the big picture.

Ask the coach about your last game

Paste the PGN, find the moment it turned, and ask why. Free to start, no card needed.
