AFFiNE vs Memos

AFFiNE is an open-source knowledge management application that combines documents, whiteboards, and databases in a unified workspace. It operates as a local-first application with optional cloud sync and end-to-end encryption. AFFiNE supports both block-based document editing and freeform canvas-style edgeless editing.

Memos is self-hosted, lightweight memo hub inspired by Twitter's format for quick capture and plain-text notes. It provides comprehensive features for knowledge management workflows. The tool is actively maintained with regular updates and strong community/vendor support.
