Capacities is a note-taking and knowledge management app that organizes ideas as connected objects instead of files and folders. It is built for individuals.

What Capacities does

Objects and object types

Every note in Capacities is an object with a type, such as a book, a person, a meeting, or a project. You can create your own types and give each one properties, such as dates, ratings, tags, and links. Templates set how each new object of a type starts.

Links and backlinks

When you mention a person or a project, Capacities creates a two-way link automatically. Every object shows the other objects that reference it. A graph view shows the network of connections.

Daily notes

Capacities creates one note per day. Every object you create is timestamped and linked to that day. You can send thoughts from WhatsApp, Telegram, or email, and they appear in your daily note.

Pro features

Capacities Pro adds an AI assistant, calendar integrations, task management, and smart queries. The AI assistant can chat with your notes, fill in properties, and summarize or translate text. Calendar integrations connect Google, Microsoft, Apple Calendar, and CalDAV. See Pro.

Apps on six platforms

Capacities runs on the web, Windows, macOS, Linux, iOS, and Android. See Download.

API and MCP

Capacities has a public REST API with an OpenAPI spec and a TypeScript SDK. The overview is Developers. Endpoint docs: developers.capacities.io.

Capacities hosts a remote MCP server at https://api.capacities.io/mcp (Streamable HTTP, not SSE).

The official MCP Registry name is io.capacities/mcp.

Service status is at status.capacities.io.

What makes Capacities different

The competitor facts in this section come from our comparison pages. For the same question answered by users, see why people choose Capacities.

Typed objects, not pages or files

Capacities stores notes as typed objects with properties and links. Notion uses pages and databases. Obsidian uses plain Markdown files in local folders. Apple Notes uses folders and tags. See Capacities vs Notion and Capacities vs Obsidian.

Built for individuals

Capacities has no real-time collaboration, and none is planned. There are no team or organization plans. Notion uses per-seat team pricing. See What's Not Next and why we build for individuals.

Full offline access

You can open, create, and edit content in Capacities without an internet connection. Integrations and AI still need internet. Notion's offline support is limited and cloud-dependent. Tana has limited offline support. Evernote has offline notebooks on paid plans only. See Capacities vs Tana and Capacities vs Evernote.

Bootstrapped, EU-hosted, and no lock-in

Capacities is bootstrapped. There are no outside investors. User data is stored in the EU. You can export your content to Markdown, CSV, Microsoft Word, HTML, and LaTeX at any time. See Our Promise.

Who uses Capacities

More than 50,000 active knowledge workers use Capacities, as of 5 October 2026.
