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.

Turn plain text into diagrams, infographics, and presentation-ready visuals.
Paste or import your text and Napkin generates infographics, diagrams, flowcharts, mind maps, and data charts that fit your content.
Napkin Slides collaborates with you to turn ideas into complete, ready-to-present decks rather than static images.
Adjust colors, fonts, layouts, and icons, reshape individual elements, and match your brand — nothing is locked after generation.
Export visuals as PPT, PNG, PDF, or SVG and drop them into PowerPoint, Google Slides, Keynote, Notion, or any tool you already use.
