Creating a website with AI in 2025: possible, but at what price?

AI on the web in 2025: magic tool or false shortcut?

In recent years, generative AIs have changed the way websites are designed. Promise: create a site without a designer, without a developer, without an editor... in a few clicks.

But Can you really create an efficient, strategic and scalable site only with AI?

Chez Norry agency, we've tested these tools — and we're going to tell you everything.

What AI is doing well in 2025

AI now makes it possible to generate, in a few minutes:

  • Of Wireframes with Uizard or Galileo AI,
  • Of texts with ChatGPT, Jasper, Copy.ai,
  • Of visuals and illustrations with Midjourney or DALL·E,
  • ofthe HTML/CSS code with Gpt-4o or Replit AI.

➡️ example : you describe your needs to ChatGPT: “Create me a site for an organic skincare brand”

→ You get a skeleton page, a few texts, visual ideas, and sometimes even exportable code.

Result: a site works. But is it really usable? Not necessarily.

What AI can't (yet) do

Even in 2025, no AI tool knows:

  • Translate a Vision business in an efficient tree structure,
  • build a consistent user experience,
  • Writing texts SEO-friendly and engaging,
  • Guarantee a technical performance (Core Web Vitals),
  • create a differentiating brand identity.

The AI is “tinkering”, but Don't think. It produces, but Does not understand.

AI + humans: the winning combination

Chez Norry agency, AI does not replace our team. She assists him:

  • to generate initial visual or editorial ideas,
  • to create variants more quickly,
  • to automate simple tasks (tag checking, page structure),
  • to add smart features to our customers' sites.

But they are our UX designers, developers Webflow and SEO experts who:

  • Structuring information,
  • make the design consistent with your brand,
  • Write content that performs.

5 tips for using AI without sabotaging your project

  1. Don't ask the AI to “do the site”, ask it to propose : wireframes, plans, ideas.
  2. Don't use its raw texts : rework them for conversion and SEO.
  3. Test their ideas, but always validate with a UX designer.
  4. Use it to produce variants, but choose wisely.
  5. Give him repetitive tasks (product description, FAQ), not strategic.

Conclusion: AI alone makes a site, but not a good site

Creating a website with AI is possible. But it's like asking a robot to build a house: it will lay the bricks, but without solid foundations, architectural plans, or finishes.

Do you have a serious project? Test the AI... but get it supervised.
