Bring memorable words back into everyday life. Collect notes from Kindle, Apple Books, and more, then revisit them with widgets and Apple Watch.
The lines you underlined shouldn't disappear into an app you never open again.
Booko turns the highlights scattered across Kindle, Apple Books and every other reading app into cards you can actually browse — so the sentences that once moved you get seen again. And you can write down your own thoughts, ideas and journal entries too — what you read and what you think, kept in one place.
WHY BOOKO
Most highlights die where you made them. Booko gives them a shelf. No setup, no system to build. Import once, then browse, revisit and share.
IMPORT YOUR HIGHLIGHTS
Bring in highlights, excerpts and notes from Kindle (My Clippings) and Apple Books. Import once, browse forever. Book covers are matched automatically. Reading in Chinese? WeChat Reading, Dedao, Douban Read and iReader are supported too.
CARD BROWSING
Every highlight becomes a card you can flip through. Change the background, typeface, palette and layout until each passage looks the way it reads.
RANDOM REVISIT
Open Booko and run into a sentence you'd forgotten. It might come from a book you finished years ago — or answer exactly what today feels like.
COVER WALL & SHELF
Browse your library by cover. Multi-select, select all and batch delete keep things manageable even after a large import.
NOTES & THOUGHTS
Beyond organizing imported highlights, write down your own thoughts, ideas and journal entries anytime — no book required. Edit any single entry; multi-select and batch actions included.
HOME SCREEN WIDGET
Put a random highlight on your Home Screen. Choose which book categories it draws from, and how often it changes. No need to open the app at all.
SHARE IN ONE TAP
Export any excerpt as a finished card image for social, or save it to Photos. Markdown export is there too, if you'd rather pipe everything into your own notes system.
MAC AND IPHONE
Booko is now on Mac. One purchase covers iPhone, iPad and Mac. Organize on the Mac, revisit on your phone.
ICLOUD SYNC
Turn on iCloud sync and your books, notes and preferences follow you across devices. The line you underlined on your phone is already waiting on your Mac.
WHO IT'S FOR
- Readers who highlight a lot and revisit almost none of it
- People who collect sentences
- Anyone who wants reading notes as cards, not as homework
- Anyone tired of heavy note-taking apps
DESIGN
Booko is small on purpose. Reading notes don't have to become tasks, a knowledge base, or a system. Some sentences only need to be seen again, slowly, once in a while.
Import once. Browse often. Keep enjoying them.
