Lokus
The Operating System for Your Ideas·lokusmd.com
Lokus is a personal knowledge OS for macOS, Windows, and Linux that stores all notes as plain markdown files on the user's device. It combines a markdown editor, bidirectional wiki links, 2D/3D graph visualization, an infinite canvas, and a template system for thinking, researching, and creating. It is built on a local-first architecture with Tauri v2 and Rust, works fully offline, and does not transmit user data to any server.
