Objects

Your notes become real things

In Capacities, you don't create files—you create objects. People, books, projects, ideas. Each with its own structure, properties, and place in your knowledge network.

Custom types

Create any kind of object. A recipe. A company. A research paper. A movie you watched. You define what matters.

Properties

Add dates, ratings, tags, links, numbers, checkboxes—whatever makes sense for that type.

Templates

Create a template for how new objects should look. Every new book, meeting, or project starts exactly how you want.

Multiple views

Switch between lists, galleries, tables, or cards. The same data, visualized however works best for you.

"The whole idea of everything being an object works for me. Object-oriented is definitely the way to go!"

Networked Notes

Ideas connect like thoughts in your head

Link anything to anything. Watch your knowledge come alive.

Bi-directional links

Type someone's name or reference a project, and Capacities creates a two-way link automatically.

Backlinks panel

Open any object and instantly see every other object that references it. Connections you forgot you made, surfaced automatically.

Graph view

See your entire knowledge network as a living graph. Explore connections. Spot clusters. Find unexpected patterns.

Tags that work

Unlike other apps, tags in Capacities work across your entire system—not siloed in single databases.

"It felt magical the first time a connection surfaced that I hadn't made consciously."
