The AI website builder that hands you the code

Show it a site you love and describe your business. It designs every page for desktop, tablet and phone, then gives you a Next.js or HTML project you own.

  • No AI account or API key
  • Desktop, tablet and phone
  • Next.js or HTML you own

Designed like a studio, delivered as code

A design system first, then every page at three sizes, then a project you can host anywhere.

3 screen sizes at once

Desktop (1440px), tablet (810px) and phone (390px) are designed together, each with its own layout and type sizes.

0 FNJ runtime in your site

The export is plain Next.js or HTML with no FNJ script or badge, so it keeps working wherever you host it.

$25 a month to build

The Builder plan is 60 credits a month, about 4 complete sites. Every site you build is yours to keep, even after you cancel.

From a site you love to code you own

Every new site starts from a reference, because an AI that can see what you like designs far better than one guessing from adjectives. You watch each step on a live canvas and can change anything before you export.

No reference yet? Browse the design library: 76 website designs in 9 industries, each one ready to open in the builder.

Show it a site you love

Add a screenshot, the link of a site you like or your own brand files, then describe your business and the pages you need.

Watch it design every page

It plans the palette, type and reusable styles, then builds each page section by section at desktop, tablet and phone widths.

Refine by prompt or by hand

Ask for a darker hero or a new pricing section in plain words, or select any element and change its text, spacing, colors or image.

Export and host it anywhere

Download a Next.js project or static HTML, or push it to your own GitHub, then put it on the host you choose.

See what it designs

Pick a prompt to see the kind of finished site the builder aims for, on the same canvas and at the same three sizes you'll work with.

What is FNJ's AI website builder?

FNJ's AI website builder designs a complete, responsive website from your description and a site you'd like yours to look like, on a visual canvas you can edit, then gives you the code: a Next.js project or static HTML you download or push to your own GitHub.

It is built for people who care how their site looks and want to keep it: small businesses, designers, agencies and startups. It makes marketing websites, not web apps: there are no forms, store checkout or log-ins, so you link those tools from a button.

A designer that works while you watch

The first draft a good studio would make, done in minutes and handed to you as an editable design and real code.

  • 01

    Starts from a site you love

    Add a screenshot or the link of any site you admire. Our AI builder studies its layout, type, color and spacing, then designs yours in that language, with your own words and pages.

  • 02

    Planned, then built live

    It starts with a design plan (pages, palette, typefaces and reusable styles), then lands each section on the canvas as soon as it is designed.

  • 03

    Desktop, tablet and phone

    Every page is laid out at three widths side by side, with its own type sizes and stacking for each, so the site is responsive from the first prompt.

  • 04

    Light, dark or your call

    Steer it clean and minimal or sleek and dark, or let the AI take the direction from your reference and your business.

  • 05

    Edit by prompt or by hand

    Ask for a new section or a sharper headline, or click any element on the canvas and change its text, spacing, colors and images yourself.

  • 06

    Real code you own

    Download a Next.js project or static HTML, or push it to your own GitHub. No FNJ runtime inside: host it on Cloudflare, Vercel or anywhere.

What you can build with it

Marketing websites of every kind, from a one-page launch to a full small-business site, each exported as code you own.

AI website builder questions

What people ask before they build. If your question isn't here, write to us and a person will answer.

What is an AI website builder?

An AI website builder designs a website for you from a description, instead of you dragging blocks onto a template. FNJ's AI website builder designs a complete, responsive website from your description and a site you'd like yours to look like, on a visual canvas you can edit, then gives you the code: a Next.js project or static HTML you download or push to your own GitHub.

Is an AI website generator the same as an AI website builder?

Mostly, yes: AI website builder, generator, maker and creator all describe a tool that designs a site from a description. The difference that matters is what happens next. Some tools generate a site once and leave you in a template editor on their hosting; FNJ's keeps designing with you on a canvas and gives you the code.

Is FNJ a no-code website builder?

Yes. You design and edit without writing code, by describing changes or selecting elements on the canvas. Unlike most no-code builders, you also get the code at the end: static HTML or a Next.js project.

How does FNJ's AI website builder work?

You add a reference (a screenshot or link of a site you like) and describe your business and pages. The AI plans a design system (pages, colours, fonts, reusable styles), then builds every page section by section on a live canvas at three screen sizes. You refine it by prompt or by hand and export the code.

Can AI really build a whole website?

Yes, for a marketing site: home, about, services, pricing, portfolio, menu, contact pages and so on, with real copy for your business, laid out for desktop, tablet and phone. It does not build web apps: there are no forms, store checkout, log-ins or databases, so link a form or booking tool from a button if you need one.

Can I export the code from an AI website builder?

With FNJ, yes, and it is the point: download a Next.js project or static HTML, or push it to a GitHub repository you own. The code has no FNJ runtime in it, so it keeps working wherever you host it.

Can it build a website from a screenshot, an image or a URL?

Yes. Every new site starts from at least one reference, and you can add up to 3: a screenshot (upload, paste or drop it) or the link of a public page. The AI studies the layout, type, colour and spacing and designs your site in that style. Building for a brand that already exists? Drop your project's ZIP or folder instead: it reads your design tokens, stylesheets, brand guide and logo, and follows them exactly.

Does it copy the website I use as a reference?

No. It takes the look: grid, typography, palette, spacing and component style. It never reuses a reference's words, logos or images, and it doesn't rebuild a page section for section. The copy is written for your business.

Are websites made with AI good for SEO?

They can be. Every page FNJ's builder makes gets its own search title and description and a real heading structure. The exported code includes Open Graph and Twitter tags, a canonical link and structured data when you set them, and a sitemap.xml and robots.txt once you set your site's address. Static HTML is also fast to load.

Will the website look right on phones?

Every page is designed at desktop, tablet and phone widths at the same time, each with its own type sizes and layout. You can check and adjust each width on the canvas before you export.

How much does an AI website builder cost?

FNJ's AI website builder is sold in credits. Site Pack: $29 once for 50 credits (about 3 complete sites, up to 10 pages each). Builder: $25/month for 60 credits (about 4 sites a month). Agency: $99/month for 250 credits (about 16 sites a month). Subscriptions allow up to 20 pages per site. A top-up is 20 credits for $10. One prompt is 1 credit and each page it builds is 1 more; a complete 5-page site refined over 10 prompts is about 15 credits.

Is there a free AI website builder?

FNJ's builder isn't free and has no trial: the Site Pack is a one-time $29 for 50 credits, enough for about 3 complete sites. There is no subscription to cancel and no hosting fee, because you host the code yourself.

Do I need my own AI account or API key?

No. FNJ runs the AI for you. You don't need an AI subscription, an API key or any developer setup.

Can I edit the website myself?

Yes. Select any element on the canvas to change its text, spacing, colours, layout and images, or upload your own photos. While the editor is open, each prompt can be undone from the chat.

Where do I host a website made with FNJ?

Wherever you like: download it and host it on Cloudflare Pages, Vercel, Netlify or any static host, or push it to GitHub and deploy from there. FNJ doesn't host it and doesn't sit between your visitors and your site.

What are the limits of AI website builders?

FNJ's builder makes marketing websites, not apps: no forms, store checkout, log-ins or databases. It has no stock-photo library, so it leaves styled spaces for photos and you upload your own. A Site Pack site can have up to 10 pages and a subscription site up to 20.

Can ChatGPT build a website?

Yes, in two ways. ChatGPT can write code for you to assemble, preview and host yourself, and on paid plans its Sites feature (in public beta) builds and hosts a site on OpenAI's platform. FNJ's builder works on a visual canvas instead: you see every page at three screen sizes as it's designed, edit it directly, and export a Next.js or HTML project you host anywhere.

Do builder credits expire?

Credits are used up as you build: each prompt is 1 credit and each page it builds is 1 more. Site Pack and top-up credits stay on your account until you use them, and monthly plan credits renew with each billing period. The sites you build never expire: the code is yours to keep and host. If a prompt fails before it changes anything, its credit is returned.

What happens when my credits run out?

Top up, or keep going with your own AI. Every builder plan includes FNJ's MCP server: connect Cursor, Codex or another assistant that supports custom MCP servers (in ChatGPT, that means its Business and Enterprise plans) by pasting one URL, and it edits your sites on the AI subscription you already pay for, with no credits used.
