Both get called “AI chess coaches,” but they work differently. Aimchess connects to your chess.com/Lichess account and analyzes your past games — it scores you across core skills, shows where you bleed rating, and gives drills to fix it. BetterChess is a coach that plays alongside you and corrects you in the moment: it catches the blunder before you commit it, explains the better move in plain English, and turns your weak spots into targeted puzzles.
