The single biggest reason an AI-built website comes out generic is not the model. It is the brief.
"A website for my gym" contains one fact. The builder has to invent the rest: who it is for, what sections exist, what it should feel like, what colour it is, and what you actually want a visitor to do. It will invent something reasonable and forgettable, because that is the only safe answer to a question that vague.
A good brief is not longer for the sake of it. It is specific in five particular places.
What a great brief includes
1. What the business does, and who it is for. Not just the category. "A gym" and "a strength-training gym for women over 40 who have never lifted before" produce completely different sites, and only one of them knows what to put in the hero.
2. The sections you want. Hero, services, pricing, testimonials, FAQ, contact, team, gallery, case studies. If you do not name them, you get a default set, and the default set is the one every other site has.
3. The vibe or tone. Two or three words is enough: "calm and premium", "bold and playful", "editorial", "clinical and reassuring". This is what moves the typography and the spacing.
4. A colour direction. "Warm earth tones", "deep navy and gold", "monochrome with one sharp accent". You do not need hex codes. You do need a direction, or you get blue.
5. Your main goal. What should a visitor actually DO? Book, buy, call, sign up, request a quote. Everything on the page is arranged around this one answer, so leaving it out is the most expensive omission on the list.
Four worked examples
These are models, not templates. Take the one closest to your business and swap the specifics.
Med spa
A landing page for "Lumière", a modern med spa for busy professionals. Sections: hero with a "Book a consultation" CTA, our treatments (Botox, facials, laser), why-choose-us, before/after gallery, team, testimonials, pricing, and a contact + booking form. Serene, premium, elegant vibe. Soft sage-green and warm off-white palette with a refined serif for headings. Main goal: get visitors to book a consultation.
B2B SaaS
A landing page for "Northbeam", a B2B analytics SaaS for e-commerce teams. Sections: hero with a bold headline + "Start free trial" CTA and a product screenshot mockup, logo strip of customers, 3 key features with icons, how-it-works in 3 steps, an animated stats band (customers, revenue tracked), pricing (3 tiers), testimonials, FAQ, and a final CTA. Modern, confident, tech vibe. Deep indigo + a bright lime accent on near-black. Main goal: start a free trial.
Restaurant
A one-page site for "Cedar & Ember", a wood-fired neighbourhood restaurant. Sections: full-bleed hero with the ambience and a "Reserve a table" CTA, our story, the menu (starters / mains / desserts with prices), a photo gallery, hours & location with a map embed, and a reservation form. Warm, rustic, inviting vibe. Charcoal, ember-orange and cream palette with a characterful display font. Main goal: drive reservations.
Portfolio
A personal portfolio for a freelance brand designer. Sections: minimal hero with name + one-line positioning, selected work as a bento grid of case studies, an about section with a photo, services, a few client logos, testimonials, and a "Let's work together" contact CTA. Editorial, confident, lots of whitespace. Monochrome with a single sharp accent. Main goal: get project enquiries.
Notice what these have in common
Every one names a business, an audience, a list of sections in order, a tone, a palette, and a goal. That is the whole checklist, written as a paragraph rather than a form. None of them is longer than about eighty words.
You are not locked in
A brief is a starting point, not a contract. Once the first version is built you can keep talking to the builder in chat: move a section, change the palette, rewrite the headline, add a FAQ. The brief only decides how close the first attempt lands.
The reason it is worth spending two minutes on is simple. Refining a site that is nearly right is quick. Rescuing one that came out generic usually means starting the description again anyway.
A shortcut
If you would rather show than tell, use Browse designs in the wizard and pick a look from the library. The builder matches the layout, colours and typefaces of what you chose, and your description is then free to concentrate on your business rather than on the styling.
You can do both. A picked design plus a specific brief is the strongest starting point available.
