The skill gap isn't coding — it's knowing how to work with AI. Mosaic teaches that.

Get Claude — free

Claude.ai is free. No credit card, no install. Arc I runs entirely in the browser — we walk you through setup in the first challenge itself.

Accept a challenge

Each challenge has a real brief: build a notice board for a village, write a cipher for a messenger guild. Fantasy framing, real skills, actual output.

Ship something real

Every level ends with an artifact — a file, a webpage, a Python script. Your portfolio builds automatically as you complete challenges.

Level up your skills

Progress through three arcs from browser prompting to Claude Code to full projects. Finish Arc III and earn your AI Literacy Certificate.

About

Built by a student,
for students.

Mosaic was built by Stella, a student at UNC Chapel Hill, after noticing something missing: schools teach kids to write code by hand, but nobody teaches them how to actually work with AI.

The tools developers use every day — Claude, Claude Code — weren't being taught anywhere. So she built a startup to change that. Mosaic is backed by people who believe AI literacy is the defining skill of this generation.
