See your mistake. Learn the better move.
Play a game. The coach shows your wrong move with a red arrow and the better one with a green arrow. Every mistake is saved and comes back until you master it.

Try it: how the coach reviews a mistake
Try it on the board: tap a black piece, then the square to move it to.
In the app, mistakes from your own games land in My Mistake Notebook by themselves and come back after 1, 3, 7, 14 and 30 days.
How it works
A chess coach that turns every mistake into a lesson
Instead of just showing you a number after the game, ChessAI4U closes the loop: it notices the mistake, keeps it, and brings it back until it's gone.
Play. The coach talks you through it.
While you play, the coach spots forks, loose pieces and threats and says so, out loud if you like. A hint never gives the move away; it helps you find it.
Your mistake next to the better move.
Every slip lands in My Mistake Notebook. When it comes back, you play it again and see three moves: in the game, now, and the better one.
The coach learns your patterns.
After a few games the coach knows your most frequent mistake, in which part of the game you make it, and whether you're improving week to week.
Practice until it sticks.
Each mistake comes back after 1, 3, 7, 14 and 30 days until you master it. Every day the coach gives you one small step: fix a few mistakes, or play a game and watch out for one thing.
Also: one free game review every day, where you go through your game with the coach.
