*AI Builder

Write what you want changed. Your site updates in minutes.*

The AI Builder changes your site from a message: you write the request, the AI makes the change, the site is checked, and nothing goes live until you press Publish.

Ask. Watch your site change.

Six requests in a row, in a demo of the Builder studio: typography, layout, images, a new section, dark mode and translation. Each one is checked before it goes live.

Demo with six requests in a row to the Builder, each checked and published: sans-serif type and dark green buttons; the photo full width, with the headline on top; a new photo uploaded by the client; a new section with customer reviews; the site in dark tones; and a translation into Portuguese. The example site, for a café, changes with every request.

Animated demo. In the real Builder, the site and the files are yours.

Three requests, exactly as they were written

We sent these requests to the Builder on test copies of our own sites. The images show the site before and the preview after, untouched. The requests were written in Portuguese; here they are translated.

    "I want to swap the yellow for a dark green on the buttons and highlights, and the headings in a more classic serif typeface."

Four sites built from scratch by the Builder

Not a single line written by us: the AI built the whole site, from design to code, and passed the same checks. Open each one and see; HookForge is already live on its own domain.

What you can do, and what stays with us

The Builder changes your site safely. Anything involving money, data or access is still studio work.

You can ask the Builder to

  • Change texts and headings, on any page
  • Swap and add images
  • Change colours and typography
  • Change the layout and sections: add, remove, reorder
  • Create new pages
  • Translate the site into other languages
  • Write the SEO texts: titles, descriptions, image text
  • Answer questions about your site
  • Undo any change with one click

Stays with the studio

  • Online payments and checkout logic
  • Backend, servers and databases
  • User accounts and logins
  • Integrations that need access keys, and third-party embeds
  • Touching anything outside your site's folder

Need one of these? We build it, at a fixed price. Talk to me

  • Only on JoaoDG sites

    It works on the Astro sites built and hosted by JoaoDG.

  • Checked before it goes live

    Every change goes through the gate: if something gets worse, it is not published.

  • What is mandatory stays

    The legal pages and the "Site por joaodg.pt" footer line always stay.

*AI Builder

House rules come built in

Every change goes through the same checks as a site we build, before it reaches you.

  1. LegalLegal pages, cookies and the complaints book stay in place: the check refuses anything that removes them.
  2. AccessibilityChecked on every change, as on the sites we build: contrast, alt text and keyboard.
  3. SpeedThe site stays static, light and fast on mobile, with the same code as ours.
  4. SecurityThe AI only touches your site's folder: no passwords, no servers, no other clients.
*AI Builder

How it works

From request to live site, in four steps.

  1. Create your site

    Start at app.joaodg.pt/criar-site, or ask us to connect the Builder to the site we already built for you.

  2. Write the request

    In your own words, like a message: "Add a section with the reviews." You can attach photos and text.

  3. The AI works, the gate checks

    The AI only touches your site's folder. Before it reaches you, the site is built and checked: legal pages, accessibility, nothing broken.

  4. Preview and publish

    The change shows up in a preview next to the chat. Publish when you want; if you don't like it, discard it or undo it later with one click.

*AI Builder

Pay for what you ask

The Builder runs on credits, at about €1 each: 300 credits are enough to build a site. Each request costs by the steps the AI took (1 credit per 2), and only when it changes the site.

100 credits to startYour first site comes with 100 free credits, to try it without paying anything.

Every month you earn credits with missions, up to your care plan's limit: fill in the store setup form, connect your own domain, pay the invoice on time and publish at least 3 changes with the Builder. Unused ones carry over to the next month, up to 20; purchased credits never expire.

Mission credits per month

  • 30Entry
  • 40Basic
  • 60Total

No plan, no missions.

Frequently asked questions

Is it safe to let an AI touch my site?

The AI works locked inside your site's folder: it only reads and writes pages, styles and images. It can't see passwords or servers, can't run commands and can't reach other clients' sites. Every request is logged, with what changed.

What if I don't like the result?

Nothing goes live until you press Publish. In the preview you can discard the change; once published, undo it with one click and the site goes back to how it was. Undoing costs no credits.

How do I know it won't break anything?

Before it reaches the preview, the site is built and checked: legal pages, 404 page, accessibility, punctuation and the footer credit. If something gets worse, the AI gets one round to fix it; if it can't, the request is undone and you don't pay.

What doesn't the AI do?

Online payments, logins, databases, integrations that need access keys and anything outside the site's folder: that stays with the studio. It also never invents data: a missing tax number, address or price is flagged for you to fill in.

How long does it take?

Most requests are ready in a few minutes, checks included. The examples above took between 1 and 5 minutes.

Does it work with any site?

With the Astro sites built and hosted by JoaoDG, including the ones you create at criar-site. For another site, talk to us: migrating often pays off.

How do I buy credits?

In the client area, in the Builder's Credits drawer: pay by card and the credits land in your balance right away, for all your sites.
