A calm, private notebook that lives entirely on your Mac

Free while in development · macOS 14 or later
Headings, to-dos, bullets, toggles, tables, callouts, quotes, code. Type “/” and the page takes whatever shape your thinking needs — at the speed of a native app.

Twenty-two themes, each with its own canvas, typeface, accent, and code colors — from the warm Hearth default to Arctic mornings and Synthwave nights. Covers and icons give every page a face.

Backlinks show every page that mentions this one — with the sentence around the mention. Search all pages from the sidebar, jump anywhere with the quick switcher, and find & replace within a page.

Your whole workspace is one readable JSON file in your own Application Support folder, images beside it. Open it in any editor. Back it up like anything else you own.
// workspace.json
"title": "Project notes",
"blocks": [ …your words, readable… ]
Up to 60 version snapshots per page, a daily backup of the whole workspace, and thirty days of grace for anything you delete. Undo reaches across everything you do.
Export any page as Markdown, HTML, or PDF — or the whole workspace at once. Import a folder of Markdown and it becomes pages. A tool you can walk away from is a tool you can trust.
Every action one ⌘K away; jump to any page with ⌘P.
Jot from the menu bar anytime — it lands in your inbox page.
**bold**, ## headings, - lists — they become real as you type.
⌘. hides everything but the page you're thinking in.
Real rows and columns that grow exactly where you ask.
Drop them in, resize by hand, tap for a full-screen look.
Highlighting in 18 languages, colored to match your theme.
Separate rooms for separate lives — work, home, the novel.
Turn any page into a starting point you can reuse.
Lasso, ⇧-click, and drag whole ideas around as blocks.
⌘[ walks back through pages; breadcrumbs show where you are.
Word count and reading time sit in the footer, never in the way.
The tools we think in have quietly become places we're watched. Notes apps grew accounts, then sync, then features reading everything you write — and somewhere along the way, opening your own notebook started feeling like opening a tab.
Locus is a bet in the other direction: that a notes app can be as pleasant as the polished cloud tools — the blocks, the covers, the delight — while remaining what a notebook has always been. Paper. Yours. Private by construction, not by policy.
It's a small, warm room on your Mac. Come think in it.
— the maker of Locus
In a human-readable JSON file inside your user Application Support folder, with images stored alongside it. Locus also writes a daily backup and keeps per-page version snapshots next to your workspace. You can open the file and read your words with any text editor.
No. Locus contains no account system and no sync service — your work never leaves this Mac unless you export it yourself. Standard tools like Time Machine protect it the same way they protect everything else you own.
Always. Export any page as Markdown, HTML, or PDF, or export the whole workspace at once — including a folder of your assets. Import works too: point Locus at a folder of Markdown and it becomes pages.
macOS 14 Sonoma or later. Locus is a native Swift app — it launches fast, scrolls smoothly, and respects your machine.
Not today. Locus is deliberately Mac-first — built with native macOS text machinery rather than a cross-platform shell, because the writing feel is the whole point.
Locus is in active development, sharpened daily on real writing.
