Capacities

Capacities is an object-based note-taking and knowledge management app for individuals. Daily notes capture ideas fast, structured object types organise people, books, projects and meetings, and backlinks plus Related Content reveal connections. Available on web, desktop and mobile, with a free plan and EU hosting.

Capacities is a note-taking and knowledge management application built around objects rather than folders. Instead of filing notes into nested directories, users create structured object types such as Person, Book, Project or Meeting, each carrying its own properties, and link them freely. A daily note acts as a low-friction inbox: you write first and organise later, and connections between objects accumulate over time. Backlinks show every reference to an object, while a Related Content feature scans your writing and surfaces places where you touched on the same subject without linking it. The product is aimed at individual knowledge workers, including writers, researchers, students, developers, managers and founders, rather than teams. The company states it builds for individuals, avoids collaboration features and enterprise bloat, and is funded by users rather than venture capital. In practice a session starts with the daily note, where you capture whatever is in front of you. As material accumulates, you promote a meeting to a Meeting object or a book to a Book object, adding the object types you actually need. Daily notes then link back to those objects, and the graph grows without a filing decision at every step. Capacities also handles saved links and images, and the marketing shows a task dashboard where status and priority sit in context next to the related notes. Custom object types and an AI Assistant are highlighted for writers planning characters, worlds and research banks. The app is available on the web plus Mac, Windows, Linux, iOS and Android, and data is hosted in EU data centres with encryption and GDPR compliance. Among personal knowledge tools, Capacities sits between the freeform graph approach of Roam Research and Obsidian and the database flexibility of Notion. It trades configuration depth for a built-in structure that works out of the box: the homepage explicitly pitches no plugin rabbit holes and no markdown syntax to memorise. Full export to standard formats is offered, so the lock-in risk is lower than with some rivals. Pricing details beyond a free forever plan and a student discount on annual Pro are not spelled out on the homepage, so buyers should confirm current tiers before committing.
