Score: 7.3/10 (Innovation: 7, Technical: 8, Documentation: 9, Utility: 5)

A native GNOME Markdown viewer/editor written in Vala with GTK4 and libadwaita, featuring a custom Markdown parser that renders to native GTK widgets without a web engine, and native Mermaid diagram support via a separate mermaid-gtk library. It's technically ambitious for skipping HTML/WebKit and reimplementing diagram rendering, though the niche Linux desktop audience limits its overall utility.

Target audience: Linux/GNOME desktop users and developers who work with Markdown notes
