Lokus
Lokus supports personal knowledge management on macOS, Windows, and Linux with Markdown, wiki links, graph view, and an infinite canvas.
About Lokus
Lokus is a personal knowledge management app for macOS, Windows, and Linux. It stores notes as plain Markdown files on the user's device and is designed for thinking, researching, and organizing ideas. Users can link notes with wiki links, which create automatic backlinks, and view those connections in 2D or 3D graph views. An infinite canvas supports spatial layouts and sketching, and a template system supports variables, conditionals, and loops.
The homepage says notes are stored locally and describes no cloud storage or tracking. It does not describe how plugins, including the listed Claude MCP AI-assistance plugin, handle data, so those external connections are not covered. The source does not state pricing for the app itself.
