Beautiful UI for your AI coding agent

View all styles →

Explore design styles

Browse styles. Find a voice.

Pick from 21 designed presets. Copy a full spec and hand it to your agent.

Paper

Ink on warm paper — a notebook left open.

Bento

Asymmetric tiles, packed like a careful bento.

Premium

Gallery air and zinc, one matte accent.

Neobrutalism

Hard edge, hard shadow, a slap of yellow.

See the difference
