One brief.
48 designs.
3,245 real layers.

Claude designed Vesper, a whole festival brand, in Facet (the Mac design app your AI can work in) from a one-line brief and a few rounds of feedback. Facet builds Claude's 10 calls into editable layers in 2.3 seconds.

Zoom in

Every pixel is a real layer: auto layout, components, variables, a licensed photo toned with a blend mode.

Day mode

The same screen, the same layers. One variable mode switched.

Ask, and watch it build
Describe what you want. It appears live, layer by layer, while you keep working.

Not pictures. Layers.

Real design files

Auto layout, components with variants, color variables with modes, text styles, Google Fonts, icons, photos. Saved as .facet on your Mac.

Checked, not hoped for

Every write verifies itself and reports, by layer, what did not happen: overflow, overlap, a missing font. Your AI fixes it before you see it.

It works while you work

An agent's build runs on a copy and lands whole, so you keep panning, zooming and drawing. Undo takes back any call.

Every script

Devanagari, Arabic, CJK and the rest, shaped properly, in any of Google's fonts.

Fast enough to think with

3,245 layers built in 2.3 s. Exports render on every core. Large files open without freezing the window.

Signed, and it updates itself

Notarized by Apple, and every update is verified against Facet's signing key before it installs.

For agents

A language made for models.

Your AI writes short descriptions in Facet's build language; Facet turns them into layers, measures them, checks them and says what did not work. A whole screen is one call. This is part of the Tonight screen above, as Claude wrote it:

10: build calls
48: designs
3,245: layers
2.3 s: to build them
