Chess coaching, for everyone.
World-class chess coaching used to cost $100 an hour and live behind a Grandmaster's calendar — out of reach for almost every player who could benefit. We're changing that. Stockfish 17 + a smart AI coach + a hallucination validator deliver the same caliber, free for everyone.
Three steps from game played to lesson learned.
01
Drop your game.
Paste a PGN, a Lichess link, or play one live — the coach picks up wherever you are.
02
Engine + AI analyze.
Stockfish 17 evaluates every move. Our AI coach turns the numbers into a plain-English lesson. A validator checks every claim before you see it.
03
You improve.
Drill same-motif puzzles the coach surfaces, then face Maia-2 at your rating. Progress, on loop.
GM-caliber coaching, without the bill.
A Grandmaster gives you Stockfish-grounded analysis, motif drilling, and opponent prep — for $100 an hour. We give you all of it, on demand, for nothing. Here's the stack that makes it possible.
One puzzle a day. Coached, not just rated.
Today's puzzle
Endgame · Knight fork
White to play. Find the winning move.
Drag the knight to win material. Wrong moves bounce back — same way the coach guards you mid-game.
The quality of a Grandmaster. The price of nothing.

Why I built this
"I grew up in urban-poor Mumbai. A $100/hour chess coach was never something I could ask my parents for. So I built one every kid like me can afford."
Chess Masti exists because the resources that make GMs aren't just expensive — they're closed. Coaches gate-keep behind a calendar. Books gate-keep behind a price. The engines and AI that can democratize this are public goods, and we're putting them in front of every player who can't afford the alternative.
