Description of Capacities

Capacities is a note-taking app that organizes knowledge as objects instead of files and folders. A person, a book, a project or an idea each becomes an object type with its own properties, and any object can link to any other. Backlinks show every connection, and a Related Content feature surfaces places where you mentioned something without linking it. A daily note acts as an inbox, so you can capture first and connect later. The vendor positions the app as needing no configuration, Markdown syntax or plugins, and it supports offline use, import and export, and saving content from WhatsApp, Telegram, Twitter or email.

The core product is free, and the company states that it will remain free. Capacities Basic includes unlimited spaces, objects and blocks, sync across devices, unlimited custom object types, full-text search, view-only sharing and media uploads up to 5 GB, then 100 MB per month. Capacities Pro costs $11.99 per month billed monthly, or $9.99 per month billed yearly, and adds an AI assistant, task management, smart queries, calendar integration, image, PDF and weblink analysis, Readwise and Kindle import, version history, AI chat connectors and a public API. Capacities Believer starts at $14.99 per month and adds beta access.

Pro includes only a small monthly AI budget meant for trying AI features or very light use. Regular AI use needs the Plus add-on, listed at $10 per month on monthly billing, which raises the budget and allows top-ups.

Can a general AI assistant replace it? A chatbot can summarise pasted notes, but Capacities stores and links your knowledge over time. Its AI works on what you have saved; for ad-hoc questions a chatbot is enough.
