Berlin-based object-model personal knowledge tool connecting notes, people, books, and ideas; for researchers and writers wanting a connected database rather than folder-based hierarchies.
Capacities is a Berlin-based personal knowledge management company that builds a note-taking and knowledge organization tool based on an object model rather than a document model. Where traditional note apps organize information in hierarchical folders, Capacities allows users to create typed objects — people, books, projects, ideas — and link them together in a personal knowledge graph. A note about a book can link to its author's person object, which links to related books and ideas, creating a connected knowledge base rather than isolated documents. Capacities is designed for researchers, writers, knowledge workers, and lifelong learners who want to build a personal database of interconnected knowledge rather than just a collection of notes. The daily notes feature and progressive summarization workflow make it suitable for capturing and processing information daily. Founded in 2021 in Germany, Capacities has grown through the personal knowledge management community alongside tools like Obsidian and Roam Research. The company competes with Notion, Obsidian, and Roam in the knowledge management tool market.
