Features that turn scrolling into learning.

Curio is a full-screen reading app for the curious. Everything below is built around one idea: every swipe should leave you with something worth remembering.

Read

Full-screen swipe feed

A calm, full-screen reading experience. Swipe through short reads — a hook, the point, and why it matters — instead of an endless feed of noise.

A personalized feed

Your For You mix learns what you're curious about across 17+ categories, so the reads keep getting more relevant the more you scroll.

Save, like & share

Keep the ideas worth revisiting. Save cards to read later, like what resonates, and share a fascinating read with a friend.

Short daily reading

Built for the pockets of your day. Learn something interesting every day with short curiosity reads you can finish in a swipe or two.

Explore

Build a rabbit hole

Search almost any topic, choose a world, and drop into a feed about exactly what you care about — psychology, history, science, mystery, books, career, and strange facts.

17+ categories

From science and history to money, horror-lite, and weird knowledge — a wide range of rabbit holes for curious readers.

Scenario Mode

Interactive reads that turn knowledge into choices — survival questions, career decisions, and story moments where what you pick changes what happens next.

Reader Stories

Read true stories and ideas submitted by the community, each reviewed for quality and safety before it reaches the feed.

Go deeper & stay comfortable

Curio AI

Tap any card to go deeper — explain it simpler, summarize it, quiz yourself, turn it into a story, or build a learning path. Clearly labeled and streamed in plain language.

Eye Comfort & SmartRead Display

Warm themes, calmer contrast, auto night shift, and reduce-motion options make long reading sessions easier on your eyes at night.

Soundtrack Mode

Optional focus soundtracks to read to, so you can settle into a rabbit hole without the noise of the rest of your feed.

Multilingual reading

Read Curio in English, 中文, Español, and Português — the interface and reads adapt to your language.

Turn your next scroll into something worth reading.
