Could you build this?

Partial The Markdown source editor and export pipeline are buildable, but a native AppKit editor with live, bidirectional editable preview and offline diagram rendering is hard UI and rendering work.

What it would actually take: Build a native macOS app with AppKit (via Rust bindings or Swift) and a text engine that keeps source and rendered preview in sync. Offline LaTeX, Mermaid, Graphviz, and PlantUML rendering need bundled engines, and PDF, HTML, and Word export need layout work. Editing the preview directly is the hardest part and needs experienced macOS and text-rendering engineering.
