Luna

What is Luna?

Luna is a podcast player built for active learning. It lets you highlight moments mid-episode, read AI-generated transcripts, and use spaced repetition to actually retain what you listen to — not just feel like you did.

How is Luna different from a regular podcast app?

Regular podcast apps are built for passive listening. Luna is built for learning. It adds the tools — highlights, transcripts, and AI — that turn a listening session into a study session grounded in the neuroscience of memory.

Why do I forget so much of what I listen to?

Because of the Ebbinghaus forgetting curve. Without active engagement, we forget roughly 70% of new information within 24 hours. Luna is designed to fight this directly, by making listening active and by bringing your key moments back at the right time.

Is Luna free?

Yes. Luna is free to download on both iOS and Android.

What podcasts does Luna support?

Luna supports over one million podcasts. If a show is available in the major podcast directories, you can listen to it — and highlight it — in Luna.

How does spaced repetition work in Luna?

Spaced repetition is a memory technique that schedules reviews of your highlights at increasing intervals — precisely when you're about to forget them. Luna is building this directly into the app so your podcast insights move from short-term listening to long-term knowledge.
