Toolglade’s take

Capacities is a well-designed take on personal knowledge management, and its object-based model is a genuine differentiator for people who like to organize by entities rather than folders. It strikes a nice balance between structure and approachability, less rigid than a database tool, more organized than a plain notes app. The AI features are helpful but supporting, not the main draw. It is best for individual structured thinkers; teams and those wanting minimal setup may prefer other tools. Verify current plan limits before subscribing.

Capacities is a personal knowledge management app built on an object-based model: instead of loose documents, you create typed objects, people, meetings, books, projects, and more, that carry their own structure and connect to one another. This mirrors how many people naturally think about information, organizing knowledge around real-world entities rather than folders. The app pairs this with a Graph View to visualize connections, block references to link specific pieces of content, Daily Notes as a central capture hub, and folder-less organization aided by a sidebar. An AI assistant helps summarize notes and find patterns in your data, and Capacities integrates with tools like Todoist, Gmail, WhatsApp, and Telegram for capture. Capacities appeals to structured thinkers who want more organization than a plain notes app but a friendlier on-ramp than a full database tool. It offers a free tier plus paid Pro and "Believer" plans, making it approachable for individuals building a durable, connected knowledge base.
