ChessAI4U is a learn-chess app for kids and beginners. Your coach talks to you in your own language: it gives hints during games, shows why a move went wrong and gets your next lesson ready. No account needed, and there is no chat.

A chess coach in your language
• Short coach tips while you play: a piece under attack, an unprotected piece, a fork, or mate in one. You can turn them off in Settings.
• Smart Coach finds the mistakes you make most often and suggests one step for today.
• The Mistake Notebook keeps your mistakes. Solve the same position again; purple arrows show why the move was a problem.

Chess lessons from zero, step by step
• Learning Path: 65 short lessons, from the pieces and rules to keeping your pieces safe, tactics, checkmate patterns, opening principles, making a plan and endgames.
• Each lesson is a short explanation followed by puzzles that lock it in, and the steps get harder as you go.
• Practice: chess puzzles at your level on forks, pins, skewers, discovered attacks and mates.
• Piece paths: a mini game for little ones that teaches how each piece moves by collecting stars.

Get better by playing
• 100 levels against the computer, with a new opponent with their own character every ten levels.
• Play the computer offline, without internet, or play a friend on the same device (2 players).
• A short analysis after each game: your accuracy and number of mistakes.
• Your game strength is worked out as you play, and Profile shows how you are improving.

Safe online chess
• Find an opponent: a 10-minute game with someone searching right now. Your opponent only appears as "Opponent": no name, photo, country or chat. Only moves are shared.
• Play a friend: share a game code and play together. You can also send a friend a puzzle.

For parents
• No chat or messaging.
• No name or email is asked for. Signing in with Google is only for backup, is optional and is open to ages 13 and over.
• Ads are child-appropriate and non-personalised. Lessons, puzzles and review have no ads.
• Settings › For parents shows a weekly summary: active days, lessons done and mistakes fixed.
