Show HN: Recallie AI – Duolingo for learning anything

I built an app with a Duolingo-style structured learning system where users can generate full courses from photos, documents, or typed input. Each course includes quizzes, flashcards, and notes, and users can also turn their notes into an AI-generated podcast for audio learning.

It’s designed to help students and anyone who wants to learn a topic study smarter and retain more through interactive lessons, quizzes, and podcasts tailored to their learning style.

Built with React Native Expo.
