vs Obsidian: Same local-first philosophy with plain .md files, but HelixNotes gives you a clean WYSIWYG editor out of the box. No plugin setup, no CSS tweaking, no learning curve. Open an app, write, close it. vs Joplin: Joplin uses its own database format internally. HelixNotes stores everything as plain markdown files in folders on your filesystem. Also Tauri instead of Electron, so much lower resource usage. Both are great projects. I built HelixNotes because I wanted UpNote's UI with Obsidian's philosophy, and that combination didn't exist.
