About Readwise
Readwise is a subscription service that automatically syncs all your reading highlights from Kindle, Apple Books, articles, PDFs, podcasts, and more into one place, then resurfaces them through a daily review powered by spaced repetition. Its companion app, Readwise Reader, is a read-it-later app built for power readers that consolidates articles, RSS feeds, newsletters, EPUBs, PDFs, and YouTube videos into a single annotatable inbox.
