Puzzles made from your games
After every game, Noctie turns your most instructive mistakes into flashcard puzzles — then brings them back with spaced repetition until they stick.
Play a game, get a deck
Every game against Noctie ends with puzzles built from your own moves: the opening slip, the missed tactic, the endgame you let drift. Next time, you'll see it coming.
Your online games count too
Link your Chess.com or Lichess account, sync your latest games, and let Noctie review them. The puzzles it finds join your regular decks.
Instructive, not just biggest
Noctie judges moves the way a human would, so it picks the mistakes you can actually learn from — not the ones only an engine line could refute.
Spaced repetition does the rest
Each puzzle returns just as you're about to forget it, and retires once you've mastered it. A few minutes of review a day, and your mistakes stop repeating.
A deck for every kind of mistake
Puzzles are sorted into decks: opening mistakes, missed checkmates, endgame mistakes, missed tactics and more.
The smart queue mixes them for you — or pick one deck and work on the part of your game that needs it most.
