Noctie.ai (chess AI)

Noctie is a chess training app built around a humanlike AI opponent that adapts to the player’s level. Players can use it for full games and custom positions with optional move-quality feedback, hints, takebacks, and post-game review. Mistakes can become flashcard-style exercises, while opening books let players choose or import lines and continue practicing the resulting middlegames and endgames. Other training material includes more than 100 interactive lessons, daily puzzles, weekly scenarios, opening repertoires, and progress history. Chess.com and Lichess accounts can be connected to import games for analysis and mistake-based practice. Noctie runs on the web, iOS, and Android. Its paid access starts with a seven-day trial, while the chess rating test remains available without starting a trial. Monthly and yearly subscriptions include the same feature set; the yearly option requires payment for the full year upfront.
