01 — new to chess?

you don’t need a rulebook. you need someone to show you.

tap any piece and it shows where it can go. ask why, and get an answer that makes sense.

02 — the why

lost in four moves? ask why.

your coach explains any move in one breath, in words you already know.

03 — it waits

it never plays for you.

no hints until you ask. want to work it out yourself? switch it to questions, and it gives you clues instead of answers.

yes, it’s ai. the patient kind.

talk to it, out loud.

ask while you play. it listens and answers, like a friend sitting next to you.

04 — practice

a million puzzles. one at your level.

tiny challenges where you find the winning move. ask for an easy one, and it’s on your board.
