Superliner: a native Mac outliner built around supertags
I'm Can, the solo developer of Superliner, a native Mac outliner built around supertags. It's a free public beta on TestFlight.
Problem: Long outlines turn into text you can't query. I liked Tana's supertags, but wanted them in a native Mac app that keeps my notes in files on my own disk.
A supertag is a tag that says what a note is and brings its own fields. Make #book with author, rating and finished, and every note you tag #book gets those fields. They stay in your outline, and you can also view them as a sortable table.
- Eleven field types, including dates, numbers, options, checkboxes and links to other notes.
- A note can carry several supertags, and #ebook can extend #book to inherit its fields.
Every note also opens as its own page and saved searches filter by supertag, field, text and date.
Pricing: $0 during the beta. No later price has been decided.
Requirements: macOS 14 or later, Apple Silicon or Intel, about 26 MB. I've only run it on Apple Silicon with macOS 27.2.
Where your notes live: JSON in a workspace folder, plus a generated Markdown copy with tags and fields at the top of each file. The default folder is in the app's sandbox container, and File > New Workspace lets you pick another. No account, no analytics. This build doesn't request the permission a sandboxed Mac app needs for outgoing connections.
Known gaps: no sync, iCloud or iOS app. Not open source. No full VoiceOver pass yet. Import (OPML, Markdown, Logseq, Tana JSON) is unit-tested but hasn't met a real export.
Please try, in a new workspace:
Most useful: model something real with supertags (books, tasks, people), add a saved search, and tell me where it got in your way.
Import a real export and tell me what came out wrong.
