Notes & Knowledge Bases arenaNotes & Knowledge Bases
Personal knowledge management and note-taking apps built around linking, daily notes, and long-lived personal archives, judged on local-first data ownership, linking and graph depth, plugin ecosystems, encrypted sync, publishing, import/export portability, mobile parity, and how completely an AI agent can read and write your notes through documented APIs, URIs, and MCP servers. All-in-one team workspaces like Notion are judged in the Project Management arena; this arena is for tools whose center of gravity is your personal knowledge graph.
