FreemiumNote-taking and personal knowledge management app that organizes ideas as connected objects with bi-directional links, daily notes, and structured properties.
Tool Information
What is Capacities?
Capacities is a note-taking and personal knowledge management app that turns ideas into structured objects (instead of files and folders), connected via bi-directional links, daily notes, properties, and views, so users can capture, connect, and retrieve knowledge the way they think. It is designed primarily for individual personal use rather than teams.
Core Features
Object-based notes
Create custom object types such as people, books, projects, or ideas, each with properties, templates, and multiple views (lists, galleries, tables, cards) instead of traditional files.
Bi-directional links and backlinks
Link any object to any other; automatic two-way links and a backlinks panel surface all references to an object.
Graph view
Visualize the entire knowledge network as a living graph to explore connections, clusters, and patterns.
Daily notes
One note per day for quick capture and habit-building, with timeline view, automatic threading, and timestamped object linking.
Block-based editor
Distraction-free editor supporting headings, lists, toggles, quotes, math, code blocks with syntax highlighting for 100+ languages, Mermaid diagrams, embeds (images, PDFs, audio, video), and markdown-style shortcuts.
Quick capture
Send thoughts via WhatsApp, Telegram, email, web extension, or Raycast so they appear in the daily note automatically.
Tags
System-wide tags that work across the entire knowledge base rather than being siloed in single databases.
Capacities Pro capabilities
Adds AI features, smart queries, calendar integration, task management, and reading integrations (Readwise, Kindle, web highlights).
Data export and security
Full export in standard formats; data stored on certified EU servers with GDPR compliance and two-factor authentication.
