Capacities is an object-based personal knowledge management tool from a German team, launched in 2019, organizing notes, people, projects, and ideas as objects; the free plan offers unlimited objects, and Pro unlocks calendar and backlink views for about €10/month.

Strengths and Features

✅ Organizes knowledge around objects instead of documents, with custom object types and properties for 10+ scenarios such as book notes, contacts, projects, and ideas
✅ Built-in backlinks and graph view that auto-generate knowledge connection networks, visualizing all object relationships in 1 graph for cross-topic retrieval and review
✅ Daily notes linked with the calendar support 1-day / 1-week / 1-month timeline review, forming a closed loop from daily input to long-term accumulation
✅ Free plan allows unlimited objects and daily notes; Pro at about €10/month unlocks calendar view and backlink lists
✅ One-click import from 3 mainstream tools — Notion, Obsidian, and Roam Research — plus a developer API for automated workflows
⚠️ Launched in 2019, its plugin and third-party integration ecosystem trails Notion and Obsidian, and it lacks team collaboration and multi-user editing
⚠️ Exports are mainly Markdown/JSON, and graph relationships may be lost during migration, so long-term users should plan backups
⚠️ Interface is primarily English with limited localization docs and community resources
⚠️ Data is stored in the official cloud by default with no local-first option, worth evaluating for data-sovereignty-sensitive users

Detailed Notes

Overview

Capacities was founded in 2019 and is headquartered in Germany. It is a personal knowledge management and note-taking tool built around "objects" rather than documents. Unlike traditional note apps, Capacities organizes information into objects such as people, books, projects, ideas, and places, using custom types and properties, backlinks, and a graph view to turn fragmented information into a structured, searchable personal knowledge base.

Capacities is "built for your brain," offering daily notes, calendar views, tagging, and backlinks, plus one-click import from Notion, Obsidian, and Roam Research. As a product from an independent German team, Capacities has a clear focus and a restrained interface, making it a favorite among deep users maintaining a long-term personal knowledge system, and it is often used for reading notes, research, and project records.

Key Strengths

Object-first organization: Objects replace documents as the core unit, with custom types and properties to manage book notes, contacts, projects, and ideas simultaneously, solving the "file pile-up" problem of traditional notes.
Backlinks and graph view: Auto-generate knowledge connection networks between objects to trace cross-topic threads from a knowledge management perspective, ideal for long-term knowledge systems.
Daily notes and review loop: Daily notes linked with the calendar record daily input and settle it into searchable knowledge assets, forming an "input-connect-review" loop with backlinks.
Generous free plan: The free plan supports unlimited objects and daily notes; Pro at about €10/month unlocks calendar view and backlink lists, keeping personal cost low.
Low migration barrier: One-click import from Notion, Obsidian, and Roam Research, paired with knowledge base setup approaches for a smooth switch.

Product Ecosystem

Objects

People, books, projects, ideas, and other objects form the core units, supporting custom properties and types as the foundation of knowledge organization in Capacities.

Daily Notes

A date-based log for daily ideas and tasks, linked with the calendar to form a timeline for journaling and daily review.

Graph View

A visual representation of backlink relationships between objects that helps uncover knowledge gaps and new connections.

Tags & Backlinks

Tagging and backlink lists classify objects across types, enabling flexible retrieval together with productivity tool workflows.

Import & API

Support for importing from Notion, Obsidian, and Roam Research plus a developer API for data migration and automated workflows.

Limitations

Young product with limited ecosystem: Launched in 2019, its plugin marketplace and third-party integrations trail Notion and Obsidian, and it lacks team collaboration and real-time multi-user editing.
Limited export and migration: Exports are mainly Markdown/JSON, and graph relationships may be lost during migration, so long-term users should plan backups.
Average localization: The interface is primarily English; Chinese input works but localization docs and community resources are limited.
Cloud dependency: Data is stored in the official cloud by default with no local-first option, worth evaluating for data-sovereignty-sensitive users.

Use Cases

How do I migrate from Obsidian to Capacities? Capacities has built-in import from Obsidian, Notion, and Roam Research; upload exported files to migrate, noting that graph relationships may need manual rebuilding. See knowledge base migration and setup.
