Stories
Source-backed stories and honest reading-app guides
Two clear collections: evidence-led stories to read, and product guides for choosing what should replace the scroll.
Reading-app and platform guides
Founder-written comparisons disclose Curio's role, name where competitors fit better, and link to Curio's current price, platforms, and limits.
Curio vs Deepstash: which one for daily bite-size reading?
Deepstash distills books into idea cards; Curio writes 30-second stories for the feed itself — an honest split from someone who builds one of the two.
What's the best app to stop doomscrolling?
Written by someone who builds one of the apps below — bias admitted up front, competitors recommended, one honest failure apiece.
Science and nature stories
Each story links the evidence it used and separates the narrow result from the internet-sized retelling.

There is no lead bird: each starling tracks its six or seven nearest neighbours, and turns cross the flock as a wave moving faster than any bird flies.
How does a wood frog survive winter with no heartbeat?
The wood frog spends the frozen months with no heartbeat, no breathing and no measurable brain activity, and in spring its heart restarts on its own.
Can tardigrades survive in space?
A moss animal pushes out its water, curls into a grain, takes ten days of open space, and walks away — the narrow, true version of the internet's favorite indestructible animal.
A finite daily mix of strange true things
