Revisit your highlights

Highlighting is great, but what's the point if you're never going to see any of those highlights again?

Readwise lets you quickly liberate your highlights (all into one place), and ensures that you'll actually see and use them.

Liberate your reading data

Remember what you read

How often do you finish a book, only to forget the key ideas two weeks later? We don't remember things by just reading them once.

Readwise fixes this using a scientific process called Spaced Repetition. We surface your best highlights back to you at the right times, and let you review them every day with the daily email and app.

Retain more of what you read

Tag, note, search, and organize

With your highlights all in one place, Readwise gives you the power to organize and connect these ideas in new ways. Use search to find a highlight instantly, tag it to cement its spot in your library, and then add your own annotation to it.

Get the most out of your reading

Sync to your favorite note-taking apps

Connect Readwise with your favorite note-taking tools such as Evernote, Notion, and Roam. We'll sync your highlights/notes automatically and continuously right to where you need them.
