Your AI Chess Coach, Right Beside the Board

Ever wished someone could explain a position to you: where the threats are, what to aim for, and why a move works or fails? Your AI chess coach is that companion, right beside the board, whenever a position feels hard to handle.

  • It shows, not just tells. It marks the squares that matter, points out the good moves with arrows, and plays out every line on the board.
  • It speaks your level. Plain words for a beginner, concise and precise for an expert.
  • It stays with you, move after move. Ask about any position, or any move by you or your opponent. It also speaks up on its own when one of your moves costs you something.
  • It works on your chess. Bring a position from your own games, your openings or a puzzle, or play a practice game.

Each hard position you work through becomes one you understand, and you carry that into the games that count.

What Is an AI Chess Coach?

An AI chess coach explains chess the way a good coach beside you would: what a position asks for, where the threats are, and why a move worked or failed, in words pitched at your level. ChessLogix's AI Mentor does this for any position you bring, from your own games, your openings, a puzzle or a practice game, and shows every idea on the board.

Explain any move

Ask Why a Move Worked, or Why It Failed

Pick any move in the game, yours or your opponent's, and ask. The coach grades it, names the reply that punishes it, says what was better, and leaves you one thing to remember. Every move it mentions can be played out on the board.

The AI Mentor explaining the opponent's 18...Na5, graded a Mistake: it attacks your queen but places the knight where 19.Bxa5 wins it; after 19.Bxa5 Qxa5 20.Nxd7 you win the bishop on d7; 18...Bxc5 was stronger; remember that a queen attack fails when the attacking knight is tactically loose.
  • The grade and what it cost, measured against the strongest move found.
  • The green chips are lines: click one and the board plays it, move by move.
  • Better and Remember turn one moment into something to use in the next game.

Written for you

Explained at Your Level, Not an Engine's

Tell the coach who it is talking to: Beginner, Intermediate, Advanced or Expert. Here is the same move, 18...Na5, explained twice. Only the "Explain for" setting changed; both are the coach's own words.

Explain for: Beginner (under 1000)

  • “18...Na5 attacks your queen, but the knight can be taken by your bishop.”
  • “After 19.Bxa5 Qxa5 20.Nxd7, you win Black's bishop on d7; later 21...Bg5 22.Nxg5 hxg5 leaves you three points ahead.”
  • Remember: “Do not attack the queen with a piece that your bishop can simply capture.”

Explain for: Expert (2000+)

  • “18...Na5 attacks your queen, but the knight on a5 is tactically loose.”
  • “You answer 19.Bxa5, winning the knight while attacking the queen on d8. After 19...Qxa5 20.Nxd7 and the ensuing exchanges, White remains three points ahead.”
  • Remember: “Do not chase the queen while your attacking piece can be captured with tempo.”

Watch the Lines Play Out on the Board

An explanation is only as good as the moves behind it. Every one comes with those moves, so you can step through what would have happened instead of taking the words on trust.

The AI Mentor board replaying a line after 19...Rxc5: White's bishop has just taken the queen on d8, with the evaluation bar on the left and the numbered moves of the line underneath, 20.Bxd8 highlighted.
  • Step forward and back with the arrow keys; the move on the board is highlighted below.
  • The evaluation bar is optional and off by default, so it never gives the game away.
  • Back to practice returns you to your game exactly where you left it.

Everything the Coach Can Do During a Game

Help is one click away. On its own, the coach speaks up only when one of your moves has just cost you something, and offers to show you why.

Position tip

Says what the position asks of you, a threat to meet or a loose piece to use, rings the squares that matter, then lists the good moves.

Hint

Shows the strongest moves in your position and walks you through the idea behind them, a step at a time, with a line to play on the board.

Explain any move

Yours or your opponent's, from the game or from the move list: the grade, what happens next, what was better, and the pattern to remember.

Retry from any decision

Go back to one of your moves and play something else. The earlier attempt is kept, and any two attempts can be compared.

Play both sides

Switch the automatic opponent off and make its moves yourself, to test an idea or ask what is wrong with a move you suspect.

Try later

Save a decision to come back to. It waits on the mentor page with the hints hidden, so you can try it again cold.

Your opponent

An Opponent That Plays at Your Strength

Eight levels, from a gentle beginner's opponent to full strength. Even the weaker levels play real chess and make the kind of mistakes you can learn to punish.

The AI Mentor start page: Opponent strength with levels 1 to 8 and Level 4 Intermediate selected, and Explain things for with Beginner, Intermediate, Advanced and Expert, each with its rating range.
  • Level 1 is gentle; Level 8 plays its best move every time.
  • The explanation level is separate, so a strong player can still ask for the simple version.

How a Session Works

Start wherever the confusing position is.

  1. Pick a position

    One from your games, your openings or a puzzle, or a new game.

  2. Set the levels

    Explanations from Beginner to Expert, opponent from Level 1 to 8.

  3. Ask

    What the position needs, a hint, or why any move worked or failed.

  4. Try again

    Retry the moment that mattered; every attempt is saved.

You can also paste a FEN or a PGN, or open a position from the Review board, the Opening Lab or a training puzzle with "Practice with mentor".

Frequently Asked Questions

What is an AI chess coach?

A coach that sits beside the board and explains chess in plain language: what a position needs, where the threats are, and why a move worked or failed. Instead of an evaluation number, you get the reason, at your level, with the moves shown on the board.

Can I practice a position from one of my own games?

Yes. Paste a FEN or a PGN on the mentor page, or open a position from the Review board, the Opening Lab or a training puzzle with "Practice with mentor". Import your Chess.com or Lichess games first if you want to start from them.

Is the AI chess coach free?

You can use it on a free account. Starting a session uses one credit, and free accounts receive five credits every month. Resuming a saved session is free, and hints, position tips and explanations inside a session cost nothing extra. The AI membership comes with many more credits.

Does it just tell me the best move?

Only when you ask for it. A position tip first tells you what the position needs and where to look, and the good moves come at the end. When you ask about a move, the explanation is about why: what it allowed, what the reply would have been, and what was better.

Can it explain my opponent's moves too?

Yes. Pick any move in the move list, yours or your opponent's, and press Explain. For an opponent's mistake it tells you how to punish it; for a strong move it tells you what it threatens.

What level of player is it for?

Any level. Set "Explain for" to Beginner, Intermediate, Advanced or Expert and the coach writes for that reader: simple words with every idea spelled out for a beginner, concise and technical for an expert. The opponent's strength is set separately.

How does an AI chess coach help me improve?

By turning the positions you get wrong into ones you understand. When you ask about a mistake, the coach shows what was better and leaves you one thing to remember. You can retry the moment until it makes sense, and save a position to try later with the hints hidden.

How strong is the opponent?

You choose. Level 8 is Stockfish at full strength and plays its best move every time. Levels 1 to 7 use Stockfish's own Skill Level setting, so the opponent gets weaker and makes realistic mistakes rather than random ones. You can change the level in the middle of a game.

How do I know an explanation is right?

Every explanation is written from lines Stockfish actually played out, and before you see it, any move it names that is not in those lines, or not legal in the positions they pass through, is sent back or cut. You do not have to take the words on trust either: each line is a button that plays its moves on the board.

Can an AI chess coach replace a human coach?

Not entirely. It is there for every move of every game and never tires of the same question, which no human coach can be. A good human coach still decides what to work on over months and notices things about you that a single game does not show.

Ask About the Position You Could Not Figure Out

Start from a position in one of your games, one of your openings, or a new practice game. Ask about anything you do not understand, at the level you choose. Your session is saved, so you can stop at any point and pick it up later for free.
