In-depth guides that help you actually master non-fiction
More than 12,000 book guides, 1,000+ article and topic guides, and podcast breakdowns, with new titles added weekly.
Guides are written with smart analysis and opinionated commentary, so you engage with ideas rather than skim a trimmed abstract.
Every guide has full audio narration and supports offline listening, so commutes and workouts are study time.
Follow your subscription on desktop, iOS or Android, with highlights, notes, PDF downloads and reading lists that travel with you.
Text to speech and voice AI across every device
Listen to books, PDFs, documents and web pages read aloud in a large library of lifelike AI voices.
Dictate instead of typing in almost any app, across Google Docs, Gmail, Slack, Outlook and more.
Turn documents or a short prompt into an AI podcast, and get instant summaries of what you are reading.
Use the web app, Chrome and Edge extensions, and native iOS, Android, Mac and Windows apps.
