AI landing page builder

An AI landing page builder that hands you the code

Describe your product or offer, add a landing page you like as a reference, and FNJ's AI builder designs a focused landing page: a specific headline, proof, benefits, pricing or sign-up section, FAQ and a clear call to action, at desktop, tablet and phone widths. Export it as HTML or Next.js and host it anywhere.

Built the way landing pages convert

The builder writes a page with a job, not a brochure:

  • A hero with one specific promise and one primary call to action.
  • Proof: numbers, logos or testimonials you supply.
  • Benefits and how it works, in short, scannable sections.
  • Pricing or offer details, an FAQ, and a closing call to action.
  • A search title and description written for the page.

Fast to change, fast to load

Ask for a sharper headline, a new section or a different angle in plain words, or edit any element by hand. Each prompt can be undone from the chat.

Export it as static HTML for a page with nothing to build and nothing to slow it down, or as Next.js if it's joining an app.

Sign-ups and payments

The builder doesn't include forms or checkout. Point your call-to-action buttons at the tools you already use, such as a Typeform, Tally, Calendly or a Stripe payment link.

How it works

  1. 01

    Show and tell

    Add up to 3 screenshots or links of sites you'd like yours to look like, then say what the business is and which pages you need.

  2. 02

    Watch it build

    The AI builder plans the pages, palette and type, then builds each page on the canvas, section by section, while you watch.

  3. 03

    Refine and ship

    Ask for changes in plain words or edit by hand, then download the code or push it to your GitHub.

One prompt and a screenshot of a site we liked, recorded as it happened. The builder designed a portfolio, built every page on the canvas for desktop, tablet and phone, and handed over the code. The video skips the waiting.

Landing pages: questions

Can it make a one-page site?
Yes. Ask for a single landing page and it builds one page with all the sections on it; you can add more pages later.
Can I collect emails on the page?
Link your call to action to a form tool such as Tally, Typeform or your email provider's sign-up page. FNJ's builder doesn't include built-in forms.
How many credits does a landing page take?
One prompt is 1 credit and each page it builds is 1 more, so a first landing page costs 2 credits, plus 1 for each refinement prompt after that.
Is the landing page responsive?
Yes. It's designed at desktop, tablet and phone widths at once, each with its own type sizes and layout.

Design inspiration

SaaS, app and AI website design inspiration

13 real designs in our design library, each with a prompt that opens the builder with the design as your reference. Landing pages for SaaS tools, AI products, fintech and mobile apps. They sell the product by showing it: dashboards, phone mockups and floating stat cards sit in the hero, and the page below follows a familiar order from features to pricing.
