Capacities
Object-based note-taking studio with a context-aware AI assistant
About
Capacities is an object-based note-taking app where people, books, projects, and daily notes are typed objects with properties rather than flat files. The idea is that structure emerges as you write, and everything links into a personal knowledge base with contextual backlinks. The built-in AI assistant — available on Pro — understands your connected notes and helps with writing, summarizing, and finding connections, without plugins or external tools. It syncs across web, macOS, Windows, iOS, and Android, stores data in EU data centers, and is fully founder-owned with no outside investors. Limitations: the AI requires the Pro plan, the free tier caps media storage, and teams wanting real-time collaboration should look elsewhere.
