HelixNotes

A note-taking application that stores notes as plain Markdown files on the user's own disk, solving the problem of data lock-in and bloat in existing note apps. It targets individual users, including developers and consumers, who want a clean editor with local file control. The app is positioned as a free, open-source alternative to hosted note services, offering features like tasks, wiki links, daily notes, and optional sync via WebDAV.
