Build a website or landing page with AI

What you can build

mobileCoder is a good fit for small, self-contained sites where you want control over how they look and behave. Common projects include:

• A landing page for a product, event, or waitlist
• A personal or portfolio site
• A simple marketing site with a few linked pages
• A page with a contact or signup form that sends submissions somewhere
• An interactive page such as a calculator or a small demo

If your goal is a large content site with hundreds of articles and many editors, a dedicated content platform may suit you better. For a focused page you want to shape exactly, describing it to an agent is quick.

Describe it, then refine from the preview

Start with the shape of the page. A first prompt might be "build a landing page for a note-taking app with a headline, three feature cards, a screenshot area, and an email signup at the bottom." The agent writes the code and runs it, so you see the page immediately.

From there you adjust in plain language. Change the wording, reorder the sections, swap the color scheme, make it read well on a phone. Each request updates the code and reloads the preview, so you are always looking at the real page rather than a mockup.

Forms, content, and outside services

Many pages need to do more than display text. A signup form has to send the address somewhere, and a contact form has to deliver the message. When a page needs to reach an outside service, you add the relevant API key or token in the Secrets panel and the agent writes the code that uses it.

You bring your own keys, so the page talks to the services you already run. Keep the same care you would with any credential: use scoped keys where you can and confirm what the generated code sends before you rely on it.

Check it before you publish

Because the agent generates real code, review the page before it goes live. Read the copy for mistakes, click every link and button, and submit any form to confirm the data arrives where you expect. Open the preview at a narrow width to see how it behaves on a small screen.

AI-generated code can be wrong or incomplete, so do not assume a page is finished just because it looks right. A short pass through the details catches the small errors that would otherwise reach your visitors.

From preview to a live site

Once the page looks and behaves the way you want, you have real code rather than a locked builder export, which keeps your options open for where it lives. Treat the version in the preview as a starting point you understand and can keep editing.

Plan for upkeep too. A landing page usually needs its copy refreshed, its links checked, and its form tested from time to time. Because changes are made by describing them, coming back later to update a section stays as quick as building it the first time.

Give a little thought to the basics that help a page get found and read. Ask the agent for a clear page title and description, headings that make sense in order, and image text for anyone using a screen reader. None of this is exotic, but it is easy to forget when you are focused on how the page looks, and it makes a real difference to how the page performs once it is out in the world.
