Kern: Remember What You Read

You spent ten hours reading that book. A month later, three ideas survive.

Kern keeps the books you finish alive. Type a title, and it becomes a deck of sharp, swipeable cards: the key ideas, examples, and surprising claims, written like a smart friend telling you the best parts. Then spaced repetition takes over, and the ideas resurface right as they start to slip.

HOW IT WORKS

1. Add a book you've read. Just the title. No uploads, no highlights, no homework.
2. Get its ideas as cards, ready in seconds.
3. Swipe for five minutes a day. Cards from all your books interleave, and the ones you're forgetting come back.

WHY READERS PICK KERN

- Works for any book you've finished: paper, library copy, audiobook, the one no summary app has
- Original cards written from the ideas, not excerpts and not a substitute for reading
- Your whole library in one feed, so old books stay as alive as new ones
- Quick interactive cards that check what actually stuck
- Review anywhere, fully offline
- No account, no sign-up. Your reading life stays yours.

THE WALL

Every book you add lives on the Wall. Review it and it stays inked. Neglect it and you watch it fade. No streaks, no guilt trips, no leaderboards. Just an honest picture of what's still in your head, and five calm minutes a day to keep it there.

PRICING

Your first two books are free, no payment needed. Keep going with Kern Plus (monthly or yearly subscription, unlimited books) or unlock a single book with a one-time purchase.
