Poussée

/poo-SAY/

From the French la poussée du pion — the pawn push.

In chess, a single pushed pawn can decide the game. In learning, a single push — the right explanation at the right moment — can change how you see the board forever.

That's what the AI coach does. Not just "bad move." But why it was bad, what you missed, and how to see it next time.

THE MISSION

Chess learning that respects your time, your data, and your intelligence.

🧠

AI Coach that talks

Every move gets a plain-English explanation. Not cryptic symbols. Not "??". The coach tells you why your move was wrong and what was better — in words you understand.

🎯

Your mistakes become puzzles

Poussée mines your blunders and turns them into personal training. Fix the holes in your game, not someone else's.

THE DIFFERENCE

Why not chess.com? Why not Lichess?

chess.com

Charges $99/year to explain why your move was bad. Limits you to 10 puzzles a day. Runs ads on the free tier. Forces account creation to play a bot.

Lichess

Free and open source — we respect that enormously. But no AI coaching. No personalized training. No bot personalities. Functional, but clinical.
