Cogi

You read great books. You highlight powerful ideas. Then you forget them.

Cogi fixes that. It takes the quotes and highlights from the books you've read and resurfaces them daily using spaced repetition. The same memory technique used by language learners and medical students. Ideas come back to you at scientifically timed intervals so they actually stick.

Every morning, Cogi serves you a handful of highlights on beautiful, minimal cards. Swipe right if it resonated, left to see it again sooner, or up to remove it. That's it. No clutter, no feeds, no noise, just the wisdom you already collected, working its way into how you think.

Features:
- Daily highlight cards with swipe gestures
- Spaced repetition intervals that adapt to your reviews
- Quote Mix to control which books appear more or less
- Customizable daily highlight count (3 to 15)
- Share beautifully designed quote cards
- Streak tracking with a global leaderboard
- iCloud sync across all your devices
- Light and dark mode
- Completely free, no ads

Cogi is built for readers who believe the best ideas deserve more than one reading.
