Could you build this?

Partial A basic desktop Markdown editor in Tauri is simple, but building a production-grade multi-platform app with WYSIWYG Markdown parsing, Tantivy full-text search indexing, and cross-platform mobile sync demands non-trivial systems integration.

What it would actually take: The stack uses Rust for the backend (interfacing with the Tantivy search engine and native file watchers) and Tauri for cross-platform desktop/mobile rendering. The hard parts involve bidirectional WYSIWYG-to-Markdown serialization, efficient background indexing of large local vaults, and handling offline-first file conflict resolution reliably.
