How to Brief an AI to Design Your Website — Plus a Copy-Paste Template

An AI has no idea what your business does, who your customers are, or what feeling you want your site to create. It only knows what you tell it. When you type 'build me a website for my bakery,' the AI makes dozens of assumptions — wrong ones — and fills in the blanks with generic choices.

The solution is front-loading context. Before you ask the AI to do anything creative, you need to dump the raw facts of your business into the conversation. Think of it like briefing a freelance designer on their first day: they need background before they can make good decisions on your behalf.

This is true whether you're using ChatGPT to generate copy and layout ideas, a code-generation tool to build HTML, or a purpose-built AI website builder. The quality of your design brief sets a ceiling on how good the output can be.

A strong brief answers these seven questions. Work through each one before you write a single prompt.

**1. Business basics.** What do you sell, and to whom? Be specific: 'I run a mobile dog-grooming service for apartment dwellers in Austin who can't travel to a salon' beats 'I have a pet business.'

**2. Primary goal of the website.** Is it to capture leads, sell products directly, drive phone calls, build credibility, or get bookings? Pick one primary goal. Secondary goals can exist, but the AI needs a north star.

**3. Target audience.** Age range, lifestyle, pain points, and what they already believe about your category. The more precise, the better the tone and layout decisions the AI will make.

**4. Brand personality in adjectives.** Choose three to five words that describe how you want the site to feel: 'warm, no-nonsense, local' or 'sleek, premium, minimal.' These guide color, font, and copy tone.

**5. Pages and sections you need.** List them explicitly: Home, About, Services, Pricing, Contact — or whatever applies. Don't let the AI guess.

**6. Examples you like (and why).** Paste in two or three URLs of sites you admire and, critically, say what specifically you like about each. 'I like the way [site] uses white space and keeps the navigation to three items' is infinitely more useful than 'make it look like Apple.'

**7. What to avoid.** Stock-photo faces, cluttered footers, autoplay video, industry jargon — whatever you hate. Exclusions are just as powerful as inclusions in a design brief.

Below is a reusable AI prompt template. Copy it, fill in every bracket, and paste it into ChatGPT, your website builder's AI chat, or any other tool. The more specific you are inside the brackets, the better your results.

I need help designing and writing content for a small-business website. Here is my brief:

BUSINESS: [One sentence describing what you do and who you serve.]

PRIMARY GOAL: [The single most important action you want a visitor to take — e.g., 'fill out a contact form to request a free quote.']

TARGET CUSTOMER: [Describe them in 2-3 sentences: who they are, what problem they have, what they've already tried.]

BRAND PERSONALITY: [3-5 adjectives — e.g., 'friendly, reliable, local, no-fluff.']

PAGES NEEDED: [List each page — e.g., Home, Services, About, FAQ, Contact.]

SITES I ADMIRE: [Paste 2-3 URLs and explain what you like about each.]

THINGS TO AVOID: [List design or copy choices you dislike.]

TASK: Using this brief, please (a) suggest a homepage layout with section headings and a short description of what goes in each section, (b) write a headline and subheadline for the homepage hero, and (c) suggest a color palette with hex codes that fits the brand personality above.

That single prompt, fully filled in, will give you a structured layout, real copy to react to, and a starting color palette — in one pass. You can then iterate: 'Make the headline more direct' or 'Swap the testimonials section for a how-it-works section.'

One common mistake: treating the first AI output as a draft to polish rather than a starting point to react to. React to it out loud. What's wrong? What surprised you? What's almost right but not quite? That reaction becomes your next prompt.

Useful follow-up prompts after your first output: - 'The headline is too vague. Make it more specific by naming [your city / your customer type / the specific problem you solve].' - 'The tone feels corporate. Rewrite the intro paragraph as if I'm talking directly to a stressed-out parent who only has five minutes.' - 'The services section lists five items. Trim it to three and make each one focus on the outcome the customer gets, not the task I perform.'

Each round of iteration should be focused on one thing at a time. Asking ChatGPT to 'make the whole thing better' produces chaos. Asking it to 'rewrite just the CTA button text to feel more urgent' produces something actionable.

Save every version. Paste promising outputs into a running doc so you can go back to an earlier direction if a newer one goes sideways.

ChatGPT and similar large-language models are excellent for generating copy, layout logic, color ideas, and even basic HTML if you're comfortable with code. They are less good at producing a finished, live, mobile-responsive website you can hand over to a customer.

If your goal is to think through your site, workshop your messaging, or generate a content outline, ChatGPT is the right tool. Run your brief through it, iterate on copy, and use the output to inform whatever you build next.

If your goal is to have a real website live on the internet within an hour, a purpose-built AI website builder makes more sense. Tools in this category — including Template Vault, which generates a complete marketing site from a short AI conversation — handle the design system, mobile layout, hosting, and structure automatically, so you're not stitching together AI-generated HTML by hand.

The honest comparison: ChatGPT gives you more control and flexibility but requires more assembly. A dedicated tool like Template Vault trades some flexibility for speed — useful when you need something credible live today, not a custom build in six weeks. Neither is wrong. It depends on whether you're optimizing for learning or shipping.

**Too vague on the audience.** 'Anyone who needs a plumber' is not an audience. 'Homeowners in Phoenix who just bought a house built before 1990 and are worried about pipe problems' is. The more specific your audience description, the more specific the AI's copy and layout suggestions will be.

**Listing features instead of outcomes.** When describing your services or USP, owners often write 'I offer a 24-hour turnaround' rather than 'customers get their order back by the next morning so they never miss a deadline.' The AI will mirror your framing. Give it outcome language and it will write outcome-focused copy.

**Skipping the 'what to avoid' field.** This is the most skipped element and one of the most valuable. If you've seen fifty websites in your industry that all look the same and yours needs to stand out, say that explicitly. 'Avoid the clichéd hero image of a smiling team in hard hats' saves you two rounds of back-and-forth.

**Asking for everything in one prompt.** A prompt asking for a full site's worth of copy, a color palette, a font pairing, a logo concept, and a layout — all at once — produces shallow answers to every question. Break it into stages: layout first, then copy, then visual identity. Each stage gets the full attention of the model.

**Not reading the output critically.** AI-generated copy often sounds plausible but generic. Read it from your customer's point of view. If a stranger landed on that page, would they immediately understand what you do and why it's for them? If not, that's your next iteration prompt.
