Capacities is an object-based note-taking tool — meaning you don’t just create “pages,” you create things: people, projects, meetings, books, ideas, sources, and more. Instead of a pile of notes, you build a connected personal knowledge system where information stays structured and reusable over time. In a browser workflow, Capacities is great for research capture and “second brain” organization.
Capacities helps you organize knowledge as objects with properties, links, and relationships. It’s built for people who want structure, but don’t want the complexity of a full database tool.
Capacities is strongest when you’re doing knowledge-heavy work and want information to stay structured: research, writing, learning, and project work with lots of context.
Capacities is a “capture and connect” layer. Use it to store context and knowledge, then push action items into a task tool for execution. This keeps your brain clear and your work moving.
Collect notes from browsing: snippets, summaries, and links to sources.
Goal: stop losing useful info
Attach notes to objects: person, project, meeting, or source.
Goal: build reusable context
Use object views to review open projects, recent meetings, or saved sources.
Goal: stay oriented
Move tasks into a task manager and complete them in focused time blocks.
Capacities works best when you keep capture fast and structure minimal — then evolve the system slowly.
Capacities is best for people who want a personal knowledge system that stays organized: researchers, writers, learners, and builders who need context to remain connected over time.

Object-based notes sound complex, but the “secret” is to keep the number of objects small. Capacities becomes powerful when your knowledge is connected — not when you build a complicated schema. Here’s a setup that works for most knowledge work without turning your notes into a science project.
If you do research in the browser, Capacities works best when you keep your capture friction low:
Capacities keeps context — but tasks need a task tool. When you find action items, move them into Todoist or TickTick, and execute using a focus timer like Pomofocus.
A short weekly review keeps your knowledge system alive: check active projects, skim recent meetings, and tag/clean anything that feels messy. Without review, even the best system becomes a pile.
Capacities is a strong tool if you want your notes to behave like a connected system. Keep objects few, capture fast, and review weekly. That’s enough structure to stay organized — without slowing you down.
Quick answers to common questions people have when evaluating Capacities.
Capacities is used for object-based notes and personal knowledge management: connecting people, projects, meetings, sources, and ideas into a structured system.
Instead of writing isolated pages, you create “objects” (like Project, Person, Meeting, Source) and attach notes to them. This keeps your information structured and reusable across your workspace.
Notion is an all-in-one workspace with docs and databases. Capacities focuses on personal knowledge management with object-based linking and a “second brain” feel. If you want a dedicated knowledge tool, Capacities is a strong alternative.
Obsidian is a local-first, markdown-based notes tool with linking and plugins. Capacities is more object-based and guided. Choose the one that matches your preference: “markdown vault” vs “structured objects.”
Keep object types minimal, capture quickly, and review weekly. Add new object types only when you see a repeated pattern that needs structure.
