AppFlowy vs Capacities

AppFlowy is an open-source alternative to Notion that provides documents, wikis, and project management in a privacy-focused workspace. It operates as a local-first application with optional cloud sync and supports self-hosted deployments. AppFlowy uses a block-based editor and includes AI features powered by GPT-5, Gemini 2.5 Pro, and Claude 3.7 Sonnet.

Capacities is a note-taking and knowledge management app that uses an object-based approach where notes are typed entities (people, books, meetings, etc.) with relationships between them. It provides a structured way to organize interconnected information.
