Could you build this?
Partial Building a basic desktop markdown viewer in Tauri is accessible, but building a production-grade local-first editor with graph indexing, backlinks, and offline-first sync requires solid systems programming.
What it would actually take: A production-grade app like Glyph requires a Tauri (Rust) backend with a high-performance local SQLite database or inverted index (e.g., Tantivy) for instant full-text search across thousands of files. It necessitates custom AST parsers for Markdown/wikilinks to maintain a bi-directional graph in memory, alongside robust file-system watcher debouncing and conflict-free sync mechanisms. This requires proficiency in Rust concurrency, memory management, and desktop OS integration.

Concerns raised: unclear differentiation from other note-taking apps, needs stronger value proposition to justify switching costs, misleading marketing about Rust/Tauri implementation
