Why umbra

A quieter way to explore.

For moments when you want something interesting to hear, not another screen to look at.

Audio-first

Wikipedia, read aloud — on any topic you can think of.

umbra is not text with a play button attached. The flow is built for calm listening from the start.

Designed for listening

Immediate playback, background audio, and lock screen controls keep the screen out of the way.

Discover gently

Search directly, follow themed chips, or start random when you want discovery without effort.

Keep going without scrolling

Suggestions and smooth transitions keep curiosity moving without turning the app into a feed.
