✦ A field guide to everything
Fall into
anything.
Type a topic. Rabbithole turns it into a living star map of small lessons — each one branching into what to learn next.
Free to start · 5 new lessons a day
Every answer is a doorway.
How it works
Seed
Ask anything.
“How do vaccines work?” “Why does jazz sound like that?” You get one short lesson, pitched at where you are — not a wall of text.
Branch
Follow a thread.
Every lesson ends in doors: what you need first, what goes deeper, what sits next door. Tap one and a new star joins the map.
Keep
Make it stick.
Quick review quizzes turn each star from blue to amber to green as it settles in. Streaks bring you back tomorrow.
Curiosity, charted.
The map
Galaxy view
A galaxy of everything you know
Each rabbithole is a constellation. Zoom out and they become a galaxy — folders, sub-maps, and the bridges where two subjects touch.
Videos, hand-picked
Each card suggests a few short YouTube explainers that match its topic and level.
Streaks, XP and badges
Watch your knowledge grow day by day, with milestones worth celebrating.
On every device
Your map syncs to your account, so it follows you from phone to phone.
Day or night
A deep-space dark mode, and a paper-light one for reading in the sun.
Free to wander. Pro to go deep.
