How to Use AI to Design a Professional Website

Ask ten people what makes a website look professional and you will get ten vague answers: clean, modern, trustworthy. Ask a working designer and you will get a shorter list, and it will be mostly about restraint. Good spacing. A small number of colours. Text that is easy to read. A clear order in which things matter. None of that requires talent. It requires a process, and this is where AI can help, provided you stay in the driver's seat.

This article walks through that process from a blank page to a finished design, with example prompts you can copy and adapt. It is meant to be read alongside a builder, or a template platform, open in another tab. If you want the wider picture of the tools and routes first, our guide to designing a website with AI in 2026 covers that. Here we stay practical and follow a single project from start to finish.

The project we will follow

To keep this concrete, imagine a small interior design studio in Lekki. Two designers, a handful of completed apartments, and a founder who has been getting clients by Instagram and referral. She wants a website that makes a new visitor think "these people are serious" within five seconds, and gives them an easy way to request a consultation. This is an imagined case, but every step below is one you would follow for a real business.

Step 1: Write the brief, because AI cannot guess it

Design decisions come from answers to a few questions. Spend twenty minutes writing them down.

Who is the visitor? Homeowners in Lagos with a budget, planning a renovation or a new flat.
What do they want to know? What the studio has done, what it costs roughly, how the process works, and whether they can trust it.
What is the one action? Request a consultation, ideally through WhatsApp.
What is the mood? Calm, warm, confident. Not flashy.
What must be true? Real projects, real photographs, real prices or ranges, a real address.

Notice that none of this is about colours or layouts yet. A design without a brief is decoration. A design with a brief is a solution.

Step 2: Use AI to explore direction, not to decide

Now you can ask a chat assistant for help. A prompt like this works well:

"I run an interior design studio in Lekki, Lagos, serving homeowners with mid to high budgets. I want a website that feels calm, warm and confident. Suggest three distinct visual directions, each with a colour palette described in words, a font style for headings and body text, and the kind of photography that would suit. Explain the mood of each in one sentence."

You will get three options. Read them like a client reading a designer's proposals. Choose one, or combine parts. The valuable thing here is that AI is producing alternatives quickly and you are making the choice. If you find yourself accepting the first suggestion without thought, stop and ask for two more.

Then narrow it. Ask for exact colour values for your chosen direction, limited to a main colour, one accent, a light background and a dark text colour. Ask for two font suggestions that are widely available and easy to read. Write these down. They become the rules for the whole site, and having rules is what stops a site from looking random.

Step 3: Plan the pages and their order

Ask for a page structure, and for the order of sections on the homepage:

"Suggest the pages for this studio's website, and for the homepage list the sections in order, with one line saying what each section is for. Keep it to what a visitor needs to decide whether to contact us."

A typical result: homepage, projects, services, process, about, contact. On the homepage: a strong opening statement, a few featured projects, a short list of services, how it works in three steps, a testimonial from a real client, and a clear call to action. You may cut some. Fewer sections is usually better. Every extra section is another chance for the visitor to lose the thread.

A useful check: for each section, ask what a visitor would miss if it were removed. If the answer is nothing, remove it.

Step 4: Write the words before the layout

Designers say "content first", and it is worth taking seriously. A layout designed around imaginary text falls apart when real text arrives. Work on the words now.

Give the assistant your facts and ask for a draft of each section. Then rewrite. Here is what to look for as you edit:

Specific over vague. Replace "beautiful, functional spaces" with "we design open-plan living rooms and small kitchens for Lagos apartments, and manage the build".
Short sentences. Long, elaborate ones read as marketing. Short ones read as confidence.
Your voice. Read every paragraph aloud. If you would not say it to a client, change it.
Nothing invented. Delete awards, statistics and quotes that do not exist. Add real ones.
A clear next step at the end of each page: "Book a consultation on WhatsApp".

Step 5: Decide about images honestly

Images carry most of the emotional weight of a design, and this is where AI-generated shortcuts do the most damage for a business that sells real work.

A studio's value is in what it has actually built. Generated interiors show rooms that do not exist and cannot be delivered. They also risk misleading customers, which in some cases raises legal issues around advertising. Use your own photographs of your own completed projects. If your photos are mediocre, improve them: shoot in daylight, straighten the frame, tidy the room, and edit lightly. AI tools can help with retouching, such as brightening or removing a stray object, as long as the result is still a true picture of the space.

Where generated images can be useful is in abstract backgrounds, textures or illustrations that make no claim about your work. Even then, use them sparingly. If you cannot photograph something and it is essential to the page, ask whether the page needs it.

Step 6: Lay out the page with a few reliable rules

Now you can build. Whether you use a template platform or a generator, apply these rules yourself, because they are what make a page look designed.

Hierarchy

On each page, one thing should be most important, one or two things next, and the rest quieter. Achieve this through size, weight and space, not through decoration. If everything is bold, nothing is.

Spacing

Beginners crowd things. Professionals leave room. Add generous space around headings, between sections and around buttons. When a page feels cramped, increase the spacing before you touch anything else.

Alignment

Line things up. Text, images and buttons should share consistent edges. Misalignment is one of the fastest ways to make a page look amateur, and it is easy to fix.

Contrast and readability

Use dark text on a light background or the reverse, with clear contrast. Keep body text at a comfortable size, around eighteen pixels or more on a phone, with generous line spacing. Pale grey text on white looks elegant in a mock-up and is hard to read outdoors on a phone screen.

Consistency

Use your two fonts and small palette everywhere. Buttons should look the same across the site. Headings should follow the same style. Consistency is what makes a site feel like one thing instead of a collage.

Restraint with effects

AI tools love animation, gradients and sliding banners. Use them rarely. Every effect costs loading time and competes for attention. A single subtle touch is a flourish. Five is noise.

Step 7: Ask AI to critique, not just create

One of the best uses of an assistant is as a reviewer. Describe a page, or paste its text, and ask:

"Review this homepage as a sceptical visitor. What is unclear, what feels generic, and what would stop me contacting this studio? List the five biggest problems."

You will not agree with everything, and you should not, but you will often be shown weaknesses you had stopped seeing. Do the same for the visual side if your tool allows uploading a screenshot, asking it to comment on hierarchy, spacing and readability. Treat the answers as opinions from a well-read but inexperienced colleague, not as facts.

Step 8: Check the things that look fine and are not

Professional design includes the parts a visitor never sees but would notice if they failed.

Phone first. Open every page on a phone. Check that text is readable, buttons are large enough to tap, and nothing overlaps.
Speed. Time the page on mobile data. Compress images. Remove anything that slows it without adding value.
Descriptions for images. Short text for every picture. It helps accessibility and search visibility.
Working links and forms. Click everything. Submit the contact form and confirm it arrives.
Page titles and descriptions. Each page needs its own, written for people, not stuffed with keywords.
Legal basics. A privacy note if you collect information, contact details, and refund terms if you sell.

Design habits AI tends to encourage, and what to do instead

Left to itself, an assistant leans toward a few habits that make sites look generic. It is useful to recognise them so you can push back.

Too many sections. Ask for a homepage and you often receive a dozen blocks: features, benefits, statistics, testimonials, a newsletter box. Cut it down to the handful that help a visitor decide.

Superlatives everywhere. "The best", "leading", "world-class". Visitors read these as noise. Replace them with a fact you can defend.

Symmetrical, centred everything. Centred text is tiring to read in long blocks. Align body text to the left and reserve centring for short headings.

A rainbow of accents. Generated palettes often include four or five bright colours. Pick one accent and use it only for actions, such as buttons and links, so the eye knows where to go.

Icons without meaning. A row of three icons with a word under each can look designed while saying nothing. Use one only if it clarifies the text next to it.

What the finished site looks like

For our imagined studio, the result is modest and effective. A warm off-white background, one deep green accent, dark grey text, and a serif heading font paired with a plain body font. A homepage that opens with a single sentence and a photograph of a real living room, followed by three featured projects, a three-step process, one client quote used with permission, and a WhatsApp button. Five pages in total. It is not a dazzling design, and that is exactly why it works. Nothing distracts the visitor from the one thing the studio wants them to do.

Where a platform can save you effort

If your site is a business presentation, a store or a booking site, you do not have to design every screen from scratch. Our business website builder, store builder and hotel booking template give you structured pages that already handle the parts that must work: contact and lead capture, carts and checkout, availability and reservations. You set your branding, add your content and connect your own domain, and we host it. It is a template-based approach, not an AI generator, and that is deliberate. It means the design is dependable and your effort goes into content and photographs, which is where the difference between a forgettable site and a convincing one lies.

You can use every step of the process above with such a platform. The AI helps with your brief, words and critique, and the platform provides the working structure.

When to get a designer

You can achieve a perfectly professional result with the approach above. There are cases where a human designer earns their fee: when your brand needs a distinctive identity, when you are competing in a crowded market on looks alone, or when you want a site that behaves in unusual ways. A designer also helps when you have followed the process and something still feels off but you cannot say what. If that sounds like you, talk to us or send a custom request.

A checklist to finish with

I wrote a brief with the visitor, the goal and the mood.
I chose one visual direction and wrote down the colours and fonts.
I planned the pages and cut anything unnecessary.
I edited every piece of AI-written text until it sounded like me.
I used real photographs of real work.
I checked spacing, alignment, contrast and consistency.
I asked for a critique and acted on the useful parts.
I tested on a phone, on mobile data, and fixed what broke.
I registered my own domain and kept my own logins.
