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.
Highlight the web, learn in public, and build your AI clone
Mark up passages on any website or lines in a YouTube transcript from a browser extension, then keep them in one searchable library.
Highlights are shared publicly by default, so you can follow other users, react to their picks and discover sources through people with similar interests.
Generate summaries of long articles, PDFs and YouTube videos to judge relevance fast and to digest what you have already saved.
Trained on your accumulated highlights and notes, the AI clone answers in the shape of your reading history and areas of interest.
