Overview
Readwise helps readers retain and organize highlights imported from books, articles, and other reading services. Daily Review uses spaced repetition and active recall to resurface saved passages, while exports connect the library with note-taking apps such as Notion and Obsidian. Its Reader product collects articles, newsletters, PDFs, EPUBs, videos, and feeds, with annotations synced back to Readwise. AI features include Ghostreader prompts, automatic summaries and tags, document chat, and Global Ghostreader, which searches the library and returns cited answers. It is aimed at readers and researchers.
