Readwise helps you get the most out of what you read by making it fun & easy to revisit your highlights from all your favorite reading platforms in one place. Quickly synchronize your highlights from Kindle, Apple Books, Instapaper, Pocket, Medium, Goodreads, and even paper books. Then start building a daily review habit using the app and daily email. By reviewing your highlights every day, you'll retain dramatically more and you'll finally stop forgetting all the details from books you just finished! --- “Readwise is my favorite new service this year. Save highlights from Kindle, Instapaper, and now tweets... one of the best long-term personal learning tools I’ve come across.” — Caleb Hicks “Besides my Kindle, Readwise has been the most influential tech for improving my reading process.” — Blake Reichmann “If you use Kindle or Instapaper or just enjoy keeping and reading highlights, please sign up to Readwise. It will become one of your cherished services.” — Christopher Galtenberg --- ACTUALLY USE YOUR HIGHLIGHTS Highlighting is great, but why bother if you're never going to see any of your highlights again? Readwise makes it easy to quickly liberate all your highlights into one place, ensuring that you'll actually see and use them, including highlights from: • Amazon Kindle • Apple iBooks • Instapaper • Pocket • Medium • Goodreads • Twitter • Physical Books (using OCR) • Manual Input • CSV Upload STOP FORGETTING 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 solves this problem using scientifically proven learning techniques called Spaced Repetition and Active Recall. Readwise resurfaces the right highlights at the right times using a daily email and an app. Readwise even makes it possible to convert your best highlights into flashcards for added retention. TAG, NOTE, SEARCH, AND ORGANIZE With your highlights all in one place, Readwise enables you to organize and connect these ideas in new ways. Use search to find a highlight instantly; use tag to organize highlights within your library; use notes to add your own annotations. HIGHLIGHT PAPER BOOKS Readwise also makes it possible to take highlights from your physical books and papers using your phone’s camera. Just snap a pic, highlight with your finger, and have your favorite highlights saved forever. --- If you are not already a Readwise subscriber, you can get started immediately with a 30-day free trial with no credit card upfront. At the end of the trial, you will not be charged unless you choose to subscribe to Readwise Full or Readwise Lite. Price may vary by location.
