Feedback that speaks human
Every move you make is graded on a color scale from blunder to excellent — by how it looks to a human, not by centipawns.
Instant, while you play
The moment your move lands, its color appears — a quiet high-five for a strong move, a heads-up when something went wrong. Prefer to play undisturbed? Switch it off and see the grades after the game instead.
Intuition, not centipawns
Trained on billions of human games, Noctie grades a move by how promising it looks to a strong player. You aren't punished for a reasonable move refuted only by an obscure engine line.
Practical strength counts
A move that sets real problems can earn more credit than the engine's sterile first choice. Clever ideas get rewarded — not just "best" moves.
Your intuition sharpens
Because the feedback arrives right when you commit, your brain picks up the patterns on its own. Game by game, you develop a feel for which moves are risky and which are promising.
The color scale
Seven grades, from "wish I hadn't" to "hard to find".
