Capacities
A note-taking app that organizes your thinking as connected objects
Overview
Capacities treats every piece of information you save as an object rather than a plain file. A book, a person, a meeting, a project idea, each becomes its own typed object with properties, and the app links them automatically, then surfaces related content you didn't consciously connect yourself. That's a genuinely different mental model from folder-based note apps, and once it clicks for people they tend to describe it as the reason they stopped bouncing between five different productivity tools.
It's aimed squarely at individuals, not teams. The site is explicit that it wants to avoid "collaboration chaos" and "enterprise bloat," so if you need shared team workspaces this isn't the tool. The core product stays free, and paid tiers unlock AI features, smart queries, and a calendar view. Pricing is around $9.99/month if billed annually or roughly $11.99/month billed monthly, with a higher "Believer" tier that funds the company directly and unlocks extra perks, though Capacities doesn't publish exact numbers prominently on its own marketing pages, so treat these as approximate and confirm before buying.
Key Features
Object-Based Organization: Everything you save, people, books, ideas, projects, becomes a typed object with its own properties.
Link Anything To Anything: Automatic backlinks show every connection between your notes without manual tagging discipline.
Related Content Detection: The app surfaces connections you made but never consciously linked.
Daily Notes: An inbox-style entry point for capturing thoughts with zero organizational pressure.
Zero Configuration: Works out of the box without markdown syntax or plugin setup like some competitors require.
Full Data Export: Export everything to standard formats, no vendor lock-in on your own notes.

Pros
Genuinely Different Model: The object-based, auto-linking approach solves the folder-hell problem other note apps struggle with.
Free Core Stays Free: Capacities explicitly commits to keeping the core product free rather than paywalling basic note-taking.
No Setup Required: Works immediately without markdown syntax or plugin configuration.
EU-Hosted, GDPR Compliant: Servers based in the EU with encryption, which matters to privacy-conscious users.
Cons
Not Built For Teams: No real collaboration features, so it's a poor fit if you need a shared team knowledge base.
Pricing Not Clearly Published: Capacities doesn't display exact Pro and Believer prices prominently, you have to dig or check third-party sources.
Learning Curve: The object model is a genuine mindset shift from folders and files, which takes some adjustment.
Smaller Ecosystem: Fewer templates, plugins, and community resources compared to bigger players like Notion or Obsidian.
What Makes It Unique
Object-First Note-Taking: Instead of files in folders, everything is a typed, linkable object, which surfaces connections in your notes automatically instead of relying on manual tagging.
