One prompt, two pages

On the left, Opus 5.5 alone from the prompt. On the right, the same prompt as a Hallmark theme page.

Without Hallmark: the whole page Opus 5.5 built from the prompt alone.
With Hallmark: the whole theme page for the same prompt.

The issue counts come from Hallmark’s linter. Scroll to read both pages, or drag the line.

It designs before it codes

What happens between your sentence and the page.

  1. Asks for your material

    Your photos, real numbers, screenshots of your app. It never makes them up.

  2. Deals one of 50 themes

    It picks three that fit your prompt. Say custom and it designs from scratch.

  3. Lays out the page from scratch

    The sections and their order change on every build.

  4. Checks its own work

    It lints the page in a real browser, then reviews it with fresh eyes.

Fifty themes to start from

Each one is a paper, a set of type, a palette and a way with photographs. The layout is up to the build.

Almanac

Open the page

Same theme, different pages

Two prompts in Kiln and two in Midnight. Each build chose its own structure.

Kiln

Wheel House, a pottery school: hands at a potter's wheel in black and white beside the headline Learn the wheel on a weeknight.Wheel House, a pottery school Ashfield Stoneware: tall pale vases on a workshop table beside the headline Two pairs of hands, one gas kiln.Ashfield Stoneware, a ceramics shop

Midnight

Questions

Does it need an API key?

No. Photographs come from its own library of openly licensed pictures. An image key is optional.

Can it redesign a site I already have?

Yes, when you ask by name: /hallmark redesign ./site. It keeps your content, links and forms and rebuilds how the page looks. It never touches an existing site on its own.

Can I skip the themes?

Yes. Ask for a custom page and it designs from your prompt alone, with the same rules and checks.

Can it show my actual app?

Yes. Give it the URL or the folder and it runs the app and takes the screenshots itself.

Can it follow my design system?

Yes. It reads your tokens and design.md before it designs anything.

Where do the photographs come from?

Openly licensed photographs on Wikimedia Commons, credited on every page that uses them.

Will two people get the same page?

No. Each build draws its own shape, hero, nav and footer.
