Hi HN. I built this because I wanted UpNote's clean UI but with local .md files and no cloud dependency. Couldn't find it, so I built it. Stack: Rust backend (Tauri 2.0, Tantivy for search), SvelteKit + TipTap frontend. Notes are plain markdown files on your filesystem - sync with whatever you already use. AGPL-3.0, source on Codeberg: https://codeberg.org/ArkHost/HelixNotes Happy to answer questions about the stack or design decisions.
