A company that only does chess
We build chess software and chess hardware, out of Shenzhen. Everything we make serves four things: how a beginner learns, how you practise, how a game gets explained afterwards, and how a coach teaches. Nothing outside those four.
Why these four
Chess rarely stalls at one point. You get through the lessons but never practise; you practise a lot but never find out what went wrong; the child keeps going but one coach cannot watch fifteen boards. So we treat the four as one thing — one account, one set of games, one review agent.
Learn
The Post Office · 78 lessons · freeA course for people who have never played. No memorising, no long videos — six steps a lesson, and you deliver a letter. Femuey the zebra reads the questions and answers yours.
Play

Review

Teach

Keep the technology on the board
Built for actually improving
No spec-stuffing, no gimmicks. Every feature has to answer one question: does it help you play better?
We keep the complicated part
Sensors, engines and models stay behind the scenes. What reaches you is a board that works and a teacher with patience.
Say it straight
No numbers we cannot source, no hidden conditions. If we cannot do something, we would rather not put it on the page.
