DEMOCRATIZING HIGH-QUALITY CHESS EDUCATION

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.

Was 14.Bxh6 sound?
Stockfish says +1.8 — sharp but holding. The cleaner path was 14.Nd5 first; you'd be +2.4 with no defensive work. Want the full line?

HOW IT WORKS

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.

WHY THIS REPLACES A $100/HOUR COACH

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.

Stockfish 17, in your browser.

The world's strongest engine evaluates every move via WASM — locally, no servers, no per-query cost. Coaching commentary always starts from real numbers.

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.
