OlyClass

Oly turns any lesson into a classroom game in about a minute. The problem: teachers spend evenings building review games by hand, and most game tools need a device for every student. How it works: the teacher snaps a textbook page, pastes a word list or types a topic. Claude writes the question set, and the whole class plays in teams on one screen (projector, TV or touch board). The teacher's phone is the remote, joined by a 6-digit PIN or QR code. No student devices, no installs. What's inside: 33 games (Tile Grab, Lucky Wheel, Memory Match, Tug of War, Word Swat, Draw It, Claw Machine...), and every game works with every question set. English is the flagship (pictures, listening, spelling, sentence order), plus a quiz mode for math, science, history and more. A free library of 500+ ready sets, printable worksheets, classroom tools (timer, noise meter, name picker) and science simulations. The teacher side is in 8 languages. Stack: React 19 + Vite + TypeScript, PixiJS for the games, Hono on Cloudflare Workers, Durable Objects for the live rooms, D1 and R2, the Claude API for generation. Solo founder, bootstrapped, built in Hanoi. Free to start, Pro is $36/year.
