◖ Spoken non-fiction, made for sleep

Any topic, turned into a calm,

Libronox narrates real subjects — history, science, the world — all prompted and curated by our community. Every episode is grounded in real sources, runs about twenty minutes, and lives in our shared podcast tree that makes navigating topics as easy as possible. Search something that interests you, then explore the branches and leaves featuring pre-made podcasts. Stitch multiple together and our AI will seamlessly stitch them together, creating a completely unique audio experience just for you.

Listening is always free · no card needed to begin.

Hitler's rise Stalingrad Pearl Harbor Rise of the Nazis The Eastern Front European Front The Pacific War The Home Front The Second World War the grounding topic — branches grow upward, getting more specific

How a night works

No bedtime-story voice, no “drift off now” — just an accurate account, read slowly, that asks nothing of you.

1

Pick a topic

Search, browse the branching library, or generate a completely new podcast. Each episode is grounded in real sources and runs about twenty minutes.

2

Build tonight's path

Tick a few connected episodes — from the trunk up toward a leaf — and they play in order, deepening as the night goes. This is not a simple process of queing episodes together; instead they are melded into one cohesive, one-of-a-kind story created by you

3

Press play & fade

Set a sleep timer and let it run. Simple setup, no endless scrolling for the perfect podcast to fall asleep to; Simply build your own peronalised story with only a few words -- The calm comes from the voice and the pacing, never from the words.

A library that grows like a tree

Topics start at the trunk and branch upward into ever more specific episodes — a shared commons you explore the way you'd wander an Obsidian graph.

🌳

Branch anything

From any episode, fork a sub-topic into its own twenty minutes. The Second World War leads up to the Eastern Front, then to Stalingrad — as deep as curiosity goes.

♾️

Generated once, heard by many

Audio is made once and shared, so listening is always free. Only generating a new branch uses a credit — and it becomes part of the commons for everyone.

🎯

Accuracy is the feature

Every episode is grounded in real sources before it's written. Hard subjects are handled with restraint — never sanitised, never dramatised.

🏆

The best version wins

Anyone can write or attempt to prompt a fresh take on a topic. The renditions people actually listen through rise to the top — quietly, by how they're used.
