Duolingo Breaks The Barrier With Gamification
- Duolingo excels at lowering the barrier to start language learning by using gamification to drive daily engagement.
- Steve Kaufmann notes 135 million users and features like streaks and mascots that make the app almost addictive.
Duolingo Pivoted From Translation To Gamification
- Duolingo originally tried translation-based tasks but pivoted to gamified engagement after Luis von Ahn and team sought better retention.
- Kaufmann recounts the origin story linking von Ahn's earlier captcha work to Duolingo's gamification design.

- Kaufmann highlights research favoring comprehensible input for vocabulary retention over gamified drills.
