A studio for your mind: object-based notes that stay connected
Model people, books, projects and meetings as typed objects with their own properties, instead of forcing them into folders.
See every link to a note at a glance, and let Capacities surface unlinked mentions where you already wrote about the same thing.
Capture thoughts without deciding where they belong first, then link and refine them later.
On paid plans, an AI assistant works alongside your notes, and image, PDF and weblink analysis turns outside material into usable content.
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.
