A New Way to Think and Connect Your Knowledge

Capacities is a personal knowledge management tool designed for people who think for a living—writers, researchers, students, developers, and founders. Instead of organizing information in traditional files and folders, Capacities uses an object-based system where everything you care about becomes a structured, interconnected entity: people, books, projects, ideas, meetings, and more.

The Problem It Solves

Most note-taking apps force you into rigid hierarchies and endless organizing. You spend more time deciding where things go than actually thinking. Important insights get scattered across multiple apps and documents, connections between ideas stay trapped in your head, and finding what you need becomes a daily scavenger hunt. Capacities eliminates this friction by letting you capture thoughts naturally and building connections automatically.

Key Features & Capabilities

• Object-Based Thinking: Create custom object types (Person, Book, Project, Meeting, etc.) with their own properties and structure
• Automatic Connection Discovery: Backlinks show every connection at a glance, while Related Content surfaces places you wrote about something but never explicitly linked
• Daily Notes as Inbox: Start each day with a frictionless capture space—no pressure to organize immediately
• AI Assistant: Built-in AI helps you work through ideas and surface insights
• Zero Configuration: No plugins, no markdown syntax to memorize, no endless customization—just open and start writing
• Full Export: Your notes remain yours with complete export to standard formats

Who It's For

Capacities serves individual knowledge workers rather than teams. Writers use it to develop characters and plot connections. Researchers build growing libraries of resources. Students organize coursework and reading notes. The tool is specifically designed for people with ADHD and those who struggle with traditional hierarchical organization.

Privacy & Trust

Hosted in GDPR-compliant EU data centers with industry-standard encryption. User-funded rather than VC-backed, ensuring the product serves individual users rather than growth metrics. Trusted by 50,000+ knowledge workers worldwide.

What Makes It Different

Unlike traditional note-taking apps, Capacities mirrors how your brain actually works—through connections between concepts rather than nested folders. The object system creates a living network of your thoughts that grows more valuable over time as patterns and relationships emerge naturally from your daily writing practice.
