WikiHole: The Rabbit Hole That Sticks

You already fall down Wikipedia rabbit holes. WikiHole makes sure you remember where you've been.

Start with a mystery — the Dyatlov Pass incident, the Voynich manuscript, D.B. Cooper — and follow the links as deep as curiosity takes you. Every article you read gets turned into spaced-repetition flash cards by Claude AI, so the knowledge you stumble across actually stays with you. No more reading about the Antikythera mechanism and forgetting it by Thursday.

Why People Are Excited

• 60+ hand-curated rabbit holes spanning unsolved mysteries, cryptids, paranormal phenomena, sea creatures, and mythology. All instant-load, no waiting.
• AI-generated quiz cards tailored to exactly what you just read, not generic trivia.
• Real spaced repetition (SM-2 algorithm). Cards resurface just before you would forget them.
• Trail history. Every rabbit hole is saved so you can resume the Mothman thread you started three weeks ago.
• Offline support. Cached articles load without a connection.

It's the only app that turns mindless late-night Wikipedia browsing into a genuine learning habit. Included free in the Essentials plan.
