Every idea needs a sanctuary.

A calm, native Mac library for the images, films, sounds and links that shaped your taste.

Private beta for macOS. One email when it opens, nothing else.

Not a feed. Not a folder. A place.

For the things that shaped your taste, kept somewhere calm.

Native to the Mac.

Swift and SwiftUI, not a browser in disguise. It scrolls, opens and feels like the rest of your Mac.

Yours, locally.

Your library lives on your Mac. There's no account to make and no feed to feed.

Calm at any size.

Designed and tested for tens of thousands of items, so it stays quiet as your taste grows.

Open anything. The rest falls away.

Focus brings one piece forward. Ambient mode lets its colours fill the room, so you can stay with it a while.

Shown: Katsushika Hokusai, Under the Wave off Kanagawa, c. 1830–33. The Art Institute of Chicago.

Built fast. Verified hard.

AI writes a lot of our code. It never gets the final word. Every change passes five gates before it reaches you.

  1. Measure

    Reproducible baselines before anything changes, so every claim has a number behind it.

  2. Design

    The architecture is mapped before a line of production code is written.

  3. Challenge

    Independent models pull the plan apart and catch contradictions early.

  4. Spike

    Throwaway experiments test the assumptions. When the evidence disagrees, the evidence wins.

  5. Ship

    Work lands in stages, behind parity tests and regression gates.

Every release is certified against a 10,000-item library. The architecture is scaling-tested at 50,000 items.

AI speeds up the work. It doesn't lower the bar.

Some things it will never do.

  • No feed.

    Nothing is ranked, recommended or pushed at you. You decide what stays.

  • No account.

    Your library lives on your Mac. There is nothing to sign up for.

  • No surprises.

    Nothing leaves your Mac unless you send it, and AI only comes in when you invite it.

Bring Claude in, on your terms.

Sanctuary is the place. Models are visitors. Invite Claude into exactly the part of your library a task needs, and nothing more. In development, after the beta.

  • Opt-in, alwaysSanctuary is complete without AI. Nothing leaves your Mac unless you send it.
  • Scoped to the taskHand Claude a moodboard, a few references or a set of notes. Only that.
  • Narrowed firstLocal search finds the relevant slice, so a model never sees the whole library.

A studio of one, with a bigger team's habits.

Sans Labs was founded in 2026 by Sanny Shavit, a visual and product designer. He sets the direction, holds the taste and makes the final call.

Claude builds against the spec, a second model audits what was built, and measurements settle the arguments. Hundreds of automated tests stand behind every release.

A quiet place for what inspires you.
