Santranc: AI Chess Coach

Santranc is your AI chess coach — play, review, and train in one app. It pairs Stockfish engine analysis with Maia3, a human-style model that predicts what real players at your rating actually play. Instead of drowning you in “perfect” moves, Santranc gives you practical, ELO-aware guidance and plain-English coaching so you improve faster.

PLAY • Face a human-like opponent powered by Maia3 — pick the ELO you want to play against • Play rated games online: bullet, blitz, and rapid • Create a private challenge link and play a friend

REVIEW YOUR GAMES • Import games from Chess.com or Lichess, or paste a PGN • ELO-calibrated review: see the moves real players at your level choose, with probabilities • Dual analysis: the Maia3 “human” perspective alongside Stockfish evaluation and best lines • Accuracy & classifications: brilliant, great, good, inaccuracy, mistake, blunder • Critical moments: jump straight to the biggest turning points of the game

YOUR AI COACH • Ask about any position in plain language and get a clear, conversational explanation • Understand why a move is a mistake — and exactly what to play instead

TRAIN • Opening Trainer: learn real opening lines move-by-move with a live opening book • Puzzles: themed tactics tuned to your rating, including puzzles from your own games • Analysis board: explore any position freely and test your ideas

TRACK YOUR PROGRESS • See every recent game, spot recurring weaknesses, and watch your rating climb over time
