Frequently asked questions
What is 10deep?
10deep is a mobile app for exploring any topic by going 10 levels deep. You pick a subject and each level reveals a deeper, more fascinating fact than the last, powered by AI. It turns idle curiosity into a guided rabbit hole you can finish in a few minutes.
How does 10deep work?
Start with any topic, then at each of the 10 levels choose how to continue: Go Deeper to dig further into the current idea, Wander to jump to a related tangent, or Redirect to ask your own question. After 10 levels you've built a complete trail you can share.
How accurate are the facts?
Levels are written to be accurate and family-friendly, not just entertaining. If a fact looks off, Pro members can fact-check any level: the AI re-examines it and corrects it on the spot if it finds an error.
How much does 10deep cost?
10deep is free to start — your first 3 trails are completely free. After that, you can start unlimited trails by watching a short ad before each one, or upgrade to Pro. Pro removes ads and unlocks extras like fact-checking any level and the Deepest Explorers leaderboard. Pro is $0.99 per week, $3.99 per month, or $24.99 per year.
Is 10deep available on Android?
Yes. 10deep is available on both Android (Google Play) and iOS (the App Store).
Is 10deep family-friendly?
Yes. 10deep is rated 13+ and its content is kept family-friendly.
Can I share what I discover?
Yes. Any completed trail can be shared as a public link that shows the full 10-level journey in any browser — no app required. Shared trails carry your handle so you get credit, or you can share anonymously, and you can make any trail public or private. You can also see how many times your shared trail has been read.
What are Fathoms?
Fathoms are points you earn for exploring and sharing — you get them for sharing trails and for every read your shared trails receive. Pro members can also earn Fathoms by fact-checking levels and can climb the Deepest Explorers leaderboard.
