Boss Challenge

Every level ends in a harder, multi-skill challenge before you earn your next belt.

Streaks & XP0-day

Every lesson and passed practice task earns real XP — keep your streak alive as you climb.

Real Missions

Mini projects and capstones — a to-do list CLI, a spam classifier, a deployed model API.

Built to actually teach you, not just entertain you

Every mechanic below exists to make the hard parts of learning AI stick — not to gamify for its own sake.

A real code sandbox

Write actual Python, run it against hidden tests, get graded in seconds — every practice task runs in a real, isolated sandbox, not a quiz.

Gamified, not gimmicky

Belts, XP, streaks, and boss challenges track real progress through real skill — the game layer sits on top of a genuinely rigorous curriculum.

Projects, not just quizzes

Every level builds toward a mini project or capstone you actually ship — a CLI tool, a data pipeline, a model behind a live API.
