Builds web pages from a prompt that look designed rather than AI-generated
The problem it solves
You asked an AI to build your landing page and it came out with the same gradient, the same cards and the same headline style as everyone else's.
For Founders and freelancersMakers building landing pagesDesigners using coding agents
- Before
- You prompt again and again for a different look, then fix spacing and contrast by hand.
- After
- You describe the business, pick one of three themes and get a self-contained page that has been checked at eight screen widths.

Overview
Hallmark is a design skill for coding agents that builds a new web page from your prompt in one of fifty visual themes, or a custom direction. It shapes the page around what visitors came to do, uses openly licensed photos or material you give it, and checks the result in a real browser for common machine-made habits before handing it over. It can also redesign or audit an existing page by name. It suits founders, freelancers and makers who want a landing page that does not look like every other AI-built site.
Instead of only prompting for taste, it checks the finished page at eight screen widths against a list of tells that make AI pages look alike.

What you get
From the creator's documentation.
| Output | What it is | Reads |
|---|---|---|
| Fifty themes | Offers three of fifty visual themes that fit your prompt, or a custom direction | Your computer |
| Page built for its job | Places the main action where visitors expect it, such as booking or subscribing | Your computer |
| Browser checks | Checks the page at eight widths for contrast, focus and common AI-look habits | Your computer |
| Redesign and audit | Rebuilds an existing page while keeping its content, or only reports problems | Your files |
| Photos | Picks openly licensed photos from Wikimedia Commons and credits them on the page | Wikimedia Commons |
| Generated images | Only when you set a Together AI API key and ask for them | Together AI API |
Good to know
You need a landing page for a small product or service and want it to look like a designer made it. Hallmark offers three themes that fit your prompt, builds the page as self-contained HTML and CSS, and checks it in a browser before handing it over.
Limits
- The browser checks need Chrome and puppeteer-core; without them only the static checks run. Photos are loaded from Wikimedia Commons and credited on the page.
- It generates images only when a Together AI API key is set and you ask for them; otherwise it uses your material or the photo library.
