What is Readwise?
Readwise is a knowledge management platform with AI features developed by Readwise, Inc. that enables avid readers, students, and professionals to collect, organize, and revisit highlights from various sources. It leverages spaced repetition and AI features like Ghostreader for enhanced knowledge retention and synthesis. The platform serves as a central hub for knowledge workers, researchers, writers, and heavy information consumers who read to learn and actively build their knowledge base. Its core offering revolves around resurfacing and syncing, allowing users to import highlights from Kindle, Apple Books, Instapaper, Pocket, Medium, PDFs, and Twitter, which are then organized by source, author, and tags. The daily review feature, based on spaced repetition, resurfaces selected highlights at optimal intervals to foster long-term retention. Readwise Reader provides an all-in-one 'read-it-later' service for distraction-free reading and powerful in-app highlighting. Furthermore, Readwise seamlessly integrates with popular note-taking tools like Notion and Obsidian, automatically synchronizing highlights and notes. Recent AI enhancements include Readwise MCP for direct AI access to highlights, Readwise CLI for command-line interaction, and Readwise Skills for pre-built AI workflows.
