Reading tools for revisiting highlights, reading everything in one place, and buying and tracking books
Readwise makes software for readers. Its original Readwise app syncs highlights from Kindle, Apple Books, Instapaper and other sources and resurfaces them with spaced repetition, with exports to tools such as Notion and Obsidian. Readwise Reader is a read-it-later app for articles, newsletters, RSS, PDFs and ebooks with web highlighting. In November 2026 it launched Readwise Books, an invite-only app that combines an ebook store, a reading app and book tracking, positioned against Amazon's Kindle and Goodreads.
