Join 50,000+ active knowledge workers
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!"
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."
Your inbox for thoughts
Every day starts fresh. Write what's on your mind, and let the connections build over time.
Daily ritual
One note per day. The simplest way to build a knowledge habit.
Quick capture
Send thoughts via WhatsApp, Telegram, or email—they appear in your daily note automatically.
Timeline view
See how your thinking evolves day by day. Your daily notes become a timeline of your intellectual life.
Automatic threading
Every object you create gets timestamped and linked to the day.
"The daily notes became a ritual—and then I saw how they stitched together all my scattered thoughts."
Write beautifully. Think clearly.
A distraction-free editor that gets out of your way, but has power when you need it.
Block-based editing
Headings, lists, toggles, quotes, math blocks, code blocks, tables: organize your thoughts visually.
Editing shortcuts
Type / for commands, use common markdown shortcuts for formatting. Optional for everyone, powerful for those who want it.
Code block with syntax highlighting
100+ languages. Auto-complete. Mermaid diagrams. Bracket pairing. Line numbers.
Embeds
Images, PDFs, audio, video—embed them directly in your notes.
"That's the reason I love Capacities - instead of figuring out workflows, learning lots of plugins, or how to sync notes on my phone, I can just simply write and focus on what matters. Like Apple Notes, but more powerful yet simple."
Not attachments. Sources you can think with.
Every PDF, photo, recording, and saved link is its own object, on every plan. Tag it, link it, and write beside it. With Pro, Capacities reads what's inside.

"I love using WhatsApp to fire anything that comes into my mind for my daily note. So handy."
Your thoughts, protected
Your data is safe with industry-standard security practices.
"Not all software 'export' features are created equal. The folks at Capacities did it right."
Features are the what. Here is the why.
People who switched from Notion and Obsidian explain what made them stay: the structure is already built in.
“I started using it functionally from the first week.”
