Superliner Notes (Beta): Superliner is a native graph outliner for the Mac

Hi Product Hunt 👋 I’m Can, the solo developer behind Superliner.

I wanted structured notes without giving up local files. I liked Tana’s supertags, but I wanted them in a native Mac app with no account, where my notes stay on my own disk.

What makes it different

Supertags: a tag that says what a note is and brings its own fields. Tag a note #book and it gets author, rating and finished fields. A supertag can extend another, so #ebook inherits everything #book has.
Every bullet is a page: open any note as its own page, link notes to each other, and see a page’s notes as an outline, table, cards or calendar.
Saved searches: filter by supertag, field, text and date, with All and Any groups, like “books rated 4+ that I haven’t finished”.
Your files: notes are JSON in a folder on your Mac, with a Markdown copy of every note. Tags and fields are in the front matter and links are wikilinks, so the files work in Obsidian and other tools even without Superliner.

No account, no analytics, and it works offline. It’s built with Swift and AppKit, for macOS 14 or later on Apple Silicon and Intel.

It’s a free beta on TestFlight. No price has been decided, and I’ll say so before anything changes.

I’d love to hear what you think, especially:

Does the supertag idea click quickly, or does it need more explaining?
What would you need to move your notes over? It imports OPML, Markdown, Logseq and Tana exports.
What’s missing for how you take notes?

I’ll be here all day answering questions. Thanks for checking it out!
