v2.0.0MIT

The Duolingo playbook as agent skills — retention, streaks, gamification, learning science, curriculum, efficacy measurement, metrics, experimentation, growth, brand, voice, culture, hiring, platform and mobile engineering, observability, and LLM feature design. Distilled from 750 posts on blog.duolingo.com plus the Duolingo Handbook and Design System. Start at the /duolingo router; design and UI craft routes out to design-engineering.

duo-gamification

Add Duolingo-style play to any product — XP systems, juicy feedback, leagues, celebration moments, hearts/energy, and the anti-grind discipline that keeps gamification from turning toxic. Use when the user asks how to make a product fun, addictive, or "feel like a game," when designing rewards, levels, or progress, or when an existing system feels like a slot machine and they want it to feel like a craft. Source the Duolingo Handbook (Make It Fun) and the Duolingo design system.
