Capacities is a personal note-taking and knowledge management app that organizes notes as connected objects rather than files and folders, for individuals who research, write, and think for a living.
About
Capacities is a note-taking and knowledge management application for individuals that replaces the traditional files-and-folders model with connected "objects" — typed entries such as people, books, projects, and ideas that carry their own properties and link to one another. The product addresses a common problem: knowledge scattered across apps and documents, connections that live only in a person's head, and time lost deciding where each note belongs.
At a high level, users capture thoughts into a daily note that functions as an inbox, then turn entries into objects that connect automatically through backlinks and a "Related Content" feature that surfaces unlinked mentions across the workspace. The company describes itself as a small, independent, user-funded team operating fully remotely across Europe, with no venture capital investors. The product is aimed at a single user rather than teams, and does not offer real-time collaboration.
Key Features

Who It's For
Capacities is built for individuals rather than teams, and the company positions it for "people who think for a living." Researchers can collect and connect sources, PDFs, and highlights; writers can build a personal reference database for their projects; students can manage notes, tasks, and sources across a semester (with a 40% student discount on annual Pro); and developers can connect their notes to scripts and AI tools through the REST API, TypeScript SDK, and MCP server. Users seeking real-time collaboration or team workspaces will not find those features here.
