Capacities: Object-Based Personal Knowledge Studio

Capacities is a personal knowledge management tool built around an object-based data model where every piece of information is a typed object with properties and relations, designed for structured yet flexible knowledge organization.

Features

Object-Based Data Model

Every piece of content is an object with a defined type (person, book, meeting, idea, project) and typed properties, enabling structured knowledge capture that mirrors how you naturally categorize information.

Daily Notes

Calendar-integrated daily notes that serve as the primary capture surface, automatically linking tagged content to its relevant objects and building your knowledge graph organically.

Smart Connections

AI-powered connection suggestions that surface related objects and content based on semantic similarity and structural relationships, helping you discover non-obvious links in your knowledge base.

Media Integration

Native support for images, PDFs, web clips, tweets, and other media types as first-class objects with their own properties, tags, and bidirectional links.

Multiple Views

Customizable views for each object type including document, gallery, table, and graph views, with filters and grouping for creating tailored perspectives on your knowledge.

Tag System

Hierarchical tags that organize objects across types, providing a flexible cross-cutting dimension for categorization alongside the structured object type system.

Key Capabilities

Structured Yet Flexible: Combines structured data types with freeform note-taking
Backlinks & Graph: Automatic backlinks and visual knowledge graph
Templates: Customizable templates per object type for consistent capture
