Use Cases
Avid eBook Readers & Kindle Users
Perfect for readers who accumulate hundreds of highlights across multiple Kindle books but rarely revisit them.

Target Audience: Frequent Kindle and eBook readers who highlight passages but never go back to review them
Knowledge Workers & Note-Takers
Ideal for professionals who use tools like Notion, Roam, or Evernote as their 'second brain.' Readwise automatically feeds reading highlights into these systems, creating a continuous pipeline of curated knowledge that can be connected, referenced, and built upon for work projects. Target Audience: Professionals, researchers, and writers who maintain digital knowledge management systems
Lifelong Learners & Students
Designed for anyone committed to retaining what they read long-term. The spaced repetition system ensures key concepts from books and articles are revisited at scientifically optimal intervals, combating the natural forgetting curve and maximizing learning ROI from reading time.
