Right now it's just a Mac app, but iOS coming in the future for myself, sync with icloud. Notes are saves as .md files and have quick search. You can open the same folder with Obsidian if that's your jam (Obsidian always felt slow and clunky to me, I know folks love it though, so keeping it compatible).
The app is very simple, just plain text. We don't even render markdown right now, though it's coming.
Definitely vibe coded. Definitely will need some updates, but share it before it's polished.... PRs appreciated.
