doXmind

A fully local, Markdown-native knowledge workspace that lets users write in a rich editor while keeping portable .md files in their own folders. It solves the problem of cloud dependency and data lock-in by ensuring files remain the source of truth. It targets individual users and teams who value privacy and control, including developers, IT professionals, and knowledge workers. It is positioned as a local-first alternative to cloud-based note-taking tools, with no account, no cloud sync, no telemetry, and no AI runtime.
