Formats & presets
Calca is not a web-design-only tool — each frame is generated HTML/CSS sized for
a format, so the same canvas holds app UIs, marketing pages, brand cards, deck
slides, and emails side by side.
System prompt presets
The preset controls the design language Calca writes for. Pick one in
Settings → System prompt, or deep-link with ?preset=.

Sample prompts to steal
- App UI —
A fleet-tracking dashboard with a dark sidebar, four KPI cards, a route-status table, and a small map panel. - Brand card —
A 1200x628 launch announcement card for a minimal note-taking app called Jot — bold headline, one screenshot mockup, release date. - Deck slide —
A pitch-deck cover slide for a warehouse-robotics startup — big title, one-line thesis, team row, and a contact footer. - Web page —
A landing page for a sourdough bakery — warm hero with a tagline, a three-item bread menu with prices, a short story section, and a footer with hours and address.
Prompts that name the components (“dark sidebar, four KPI cards, a route-status
table”) get far better layouts than vague ones (“a cool dashboard”).
