AFFiNE

AFFiNE is an open-source, privacy-first all-in-one workspace that combines note-taking, knowledge management, and collaboration features. It offers a local-first architecture where your data stays on your device by default, with optional cloud synchronization. The platform provides a unified interface for writing docs, building knowledge bases, creating whiteboards, and managing tasks, all while maintaining complete control over your data. Built with modern web technologies, AFFiNE delivers a smooth, offline-capable experience with rich editing capabilities including markdown support, block-based editing, and visual canvas features. It serves as an alternative to tools like Notion, Miro, and Monday, targeting individuals and teams who prioritize data privacy and ownership while seeking powerful productivity features.
