Readwise Reader is a read-later and RSS reader app that combines article saving, PDF reading, and newsletter management with AI-powered summarization and a spaced repetition system for reviewing highlights. The AI can summarize lengthy articles, answer questions about saved content, and generate discussion questions. Knowledge workers, researchers, and voracious readers use Readwise Reader to centralize all reading material, capture and resurface important highlights, and extract value from content they've read over time. The AI ghost reader feature pre-highlights important passages before the user begins reading. Readwise's integration with Obsidian, Notion, Roam, and other PKM tools makes it a central layer in many knowledge management workflows. The combination of ingestion, AI assistance, and spaced repetition creates a more complete reading-to-knowledge pipeline than simple bookmarking tools.
