Cairn
Notes that are actually yours.
Cairn is a local-first outliner. Every note is a plain Markdown file on your own devices — synced across Mac and iPhone, and yours to keep.
No account. No server holding your data. No company that can lock you in or shut it down. Just files, in a format that outlives any single app.
- ◆ Outliner blocks — nest, link, and reference your thinking
- ◆ Page links, tags, and daily journals build a real graph
- ◆ Flawless iCloud sync across Mac and iPhone
- ◆ Bring your Logseq vault with you
- ◆ Connect your AI — a built-in local server, never through anyone's cloud
