You asked AI to build a page, and what came back was competent and completely anonymous. A soft purple-to-blue gradient at the top. A clean system font. Evenly spaced cards with rounded corners. It could belong to any company on earth, which is another way of saying it belongs to none. If you want to make AI match your brand, the problem is almost never the model. It is that you described the content and never described the brand.
An AI model with no brand brief behaves exactly like a designer with no brand brief: it reaches for safe, pleasant defaults. Those defaults are the reason every AI page looks vaguely the same. The fix is to stop leaving your brand to chance and hand it over on purpose, as a short, reusable block of text you paste at the top of every prompt.
TL;DR
Give AI your brand as data, not adjectives. Write a brand brief: your colors as hex codes with a rule for where each one goes, your exact fonts and their jobs, one line on the logo, two lines of voice, and a short do-not list. Paste it above any page-building prompt. Colors carry the most weight, so be specific: hex codes with placement beat “use blue” every time. Save the brief once, reuse it on every page, then publish the results to one link on your own domain so the address is on-brand too.
Why does AI-generated design look so generic?
Because a prompt like “build me a landing page for my coffee subscription” tells the model everything about the topic and nothing about the company. With no colors, no type, and no voice to work from, the model fills the gap with the statistical center of every page it has ever seen. That center is a gradient hero, a sans-serif, three feature cards, and a call-to-action button in a friendly blue.
None of that is wrong. It is just nobody’s. Your brand is the specific set of choices that makes your coffee subscription look different from the ten thousand other coffee subscriptions. If you do not supply those choices, the model cannot invent them, so it defaults, and defaults are generic by definition. This is the same reason AI pages look generic until you art-direct them: the polish lives in the direction you give, not the model you pick.
What “your brand” actually is, in terms AI can use
Brand can sound fuzzy, but for building a page it comes down to five concrete inputs. Give the model these and you have given it 90 percent of what a designer would ask for.
- Colors, as hex codes. Primary, secondary, a background, a text color, and one accent. Hex codes, always. “Navy” is a range;
#1E3A8Ais a decision. - Fonts, and their jobs. One for headings, one for body, both loadable from a web source like Google Fonts. Say which font does which job.
- The logo. Where it goes, how much space around it, and whether it sits on light or dark. Even “wordmark, top left, do not stretch it” is enough.
- Voice. Two lines. Are you plain and direct, or warm and playful, or precise and technical? Give an example sentence in your voice.
- A do-not list. The fastest way to kill generic output. “No purple gradients, no drop shadows, keep corners nearly square, no stock-photo people.”
Notice that four of the five are things you can copy straight out of an existing brand guide, a website, or a logo file. You are not inventing a brand for the AI. You are translating one you already have into a form it can act on.
How do you get AI to use your exact brand colors?
Colors are the single biggest lever, and the most common mistake is naming them instead of specifying them. “Use our blue” leaves the model to pick from thousands of blues. Give it the hex code and, just as important, tell it where each color belongs. A palette without placement rules still comes out looking random, because the model has to guess whether your accent orange is a background or a button.
Here is a color block you can drop into any prompt. Swap in your values:
Brand colors, use these exact hex codes:
- Primary #1E3A8A: primary buttons, links, active states
- Accent #F59E0B: highlights and small emphasis only, never large fills
- Background #F8FAFC: page background
- Surface #FFFFFF: cards and panels
- Text #0F172A: body copy and headings
- Muted #64748B: secondary and helper text
Rules: do not introduce any colors outside this list. Do not use
gradients. Use the accent sparingly, for one or two elements per screen.That last paragraph does as much work as the palette itself. Left unconstrained, models love to add a fourth and fifth color and a gradient or two. A short list of rules keeps the page disciplined, which is most of what “looks designed” means. If you want to go deeper on assembling a palette that actually works together, there is a whole guide to color palettes for AI pages.
The difference between naming and specifying is not subtle:
Fonts, logo, and voice: the rest of the brief
Fonts. Name the exact families and their jobs, and tell the model where to load them. Most brand fonts, or a close cousin, live on Google Fonts, and that is the easiest source for a self-contained page. If your real brand font is a paid or custom typeface the model cannot fetch, pick the nearest free web font and say so, rather than letting the model default to a system sans-serif. Type does a surprising amount of brand recognition on its own, which is why typography tips for AI pages is worth a read once the colors are locked.
Fonts: headings in "Poppins" (600 and 700 weights), body in "Inter"
(400 and 500). Load both from Google Fonts and set them as the CSS font
stacks. Headings slightly tight letter-spacing, body at 1.6 line-height.Logo. You usually cannot hand a chat model your actual logo file inside a text prompt, so describe its placement and give it room. If your logo is a simple wordmark, you can even ask the AI to set your brand name in your heading font as a stand-in until you swap the real file in. A line like “brand wordmark top-left with clear space around it, never stretched or recolored” prevents the most common logo crimes.
Voice. This shapes every word on the page, and models get it fast from a tiny sample. Do not say “professional.” Show it:
Voice: plain, direct, a little warm. Short sentences. No corporate
filler, no exclamation marks. Write headings like a person talking, for
example "Coffee that shows up before you run out," not "Premium Coffee
Subscription Solutions."The full brand brief, ready to paste
Stack the pieces and you have a reusable header for every prompt. Keep this block saved somewhere, fill it in once for your brand, and paste it above whatever you are building that day:
BRAND BRIEF — paste at the top of every page prompt.
Colors (exact hex, do not add others, no gradients):
- Primary #1E3A8A → buttons, links, active states
- Accent #F59E0B → small highlights only
- Background #F8FAFC · Surface #FFFFFF
- Text #0F172A · Muted #64748B
Fonts (load from Google Fonts):
- Headings: Poppins 600/700, slightly tight tracking
- Body: Inter 400/500, 1.6 line-height
Logo: wordmark set in Poppins, top-left, generous clear space,
never stretched or recolored.
Voice: plain, direct, a little warm. Short sentences. No corporate
filler, no exclamation marks.
Do NOT: use purple, add gradients, use drop shadows, round corners more
than 8px, or drop in stock-photo people.
Now build: [describe the page here]. Deliver one complete, self-contained
HTML file with all CSS inlined and Google Fonts linked in the head.That closing line matters as much as the brand rules. Asking for one self-contained HTML file is what keeps the page portable, so it opens and looks right anywhere you send it, with your fonts and colors intact.
Naming versus specifying: a quick reference
| Brand element | Generic prompt (guesses) | Brand-brief prompt (obeys) |
|---|---|---|
| Color | “use blue and an accent” | “#1E3A8A on buttons and links, #F59E0B for small highlights only” |
| Fonts | “a clean modern font” | “Poppins for headings, Inter for body, loaded from Google Fonts” |
| Logo | (not mentioned) | “wordmark in Poppins, top-left, clear space, never stretched” |
| Voice | “professional tone” | “plain and warm, short sentences, no exclamation marks” |
| Restraint | (none, so it adds) | “no gradients, no purple, corners no more than 8px” |
| Result | Could be anyone’s page | Recognizably yours |
Fixing off-brand drift as you iterate
Even with a solid brief, a model will occasionally wander: it sneaks in a gradient on the hero, or bumps a heading to a color that is not in your palette. Treat this the way you would a design review. Give one specific correction at a time rather than “make it more on-brand,” which the model cannot act on.
Two brand fixes:
1. The hero background is a gradient. Make it flat #F8FAFC.
2. The pricing cards use a blue that is not in the palette. Change all
card accents to the primary #1E3A8A.
Keep everything else exactly as is.Short, mechanical, one change per line. That rhythm is the same one that works for iterating on any AI-generated page, and it converges faster than one giant rewrite request. After a couple of rounds, the page holds your brand on its own, and your saved brief gets a little sharper for next time.
Keeping a whole project on-brand, then getting it live
A single on-brand page is nice. The real payoff is consistency across everything: your landing page, your pricing page, a proposal, a report, all clearly from the same company. Because your brand brief is just text, you reuse it verbatim on every prompt, and page after page shares the same palette, type, and voice with zero extra effort. That is a lightweight design system you built by writing one block of text.
The last step is getting these pages in front of people without losing the brand you just enforced. Take the self-contained HTML each prompt produced and publish it with VisiblePage: paste the HTML, or drop a ZIP for a multi-file project, and you get a live link immediately, with no build step or hosting setup. Your exact fonts, colors, and interactions come through intact, because you are sharing the real page and not a screenshot, and it loads fast from the edge wherever someone opens it. You can keep a page public, or make it private or password-protected while it is still in review.
Two features finish the brand story. Point a custom domain like get.yourbrand.com at the page, so the address matches the design instead of a random URL. And because updating the page keeps the same link, when you refine the palette or swap in the real logo, every place you shared it shows the current, on-brand version with nothing to resend.
Try it now: Publish your on-brand AI page with VisiblePage and get a live link in seconds.
Frequently asked questions
How do I make AI use my exact brand colors?
Give it the hex codes, not color names. Paste your primary, secondary, background, text, and accent colors as hex values and say exactly where each one goes: primary on buttons and links, accent for highlights only, this background, that text color. “Use blue” gets you a random blue. “#1E3A8A on primary buttons and links” gets you yours.
Can AI match my brand fonts?
Yes, if the fonts are on Google Fonts or another web source. Name the exact families and where each goes, for example headings in Poppins and body in Inter, and ask the AI to load them from Google Fonts and set them as the CSS font stack. If your brand font is a paid or custom typeface, pick the closest free web font and say so in the brief.
What is a brand brief for AI?
It is a short, reusable block of text that lists your colors as hex codes, your fonts, how to use your logo, your voice, and a few do-not rules. You paste it at the top of any page-building prompt so the AI has your brand as context every time, instead of falling back on its generic defaults.
Why does AI-generated design look so generic?
Because you did not give it a brand to work from, so it reaches for its safe defaults: a purple-to-blue gradient, a system sans-serif, evenly spaced cards, a hero with a big heading. Those defaults are fine and forgettable. The fix is not a better model, it is telling the model whose brand it is building for.
How do I keep every AI page on-brand across a whole project?
Save your brand brief once and paste it at the top of every prompt, so page after page shares the same colors, type, and voice. Then publish each finished page to a live link, and put them all on a custom domain like yourbrand.com so the address matches the design too.
The short version
AI pages look generic because you handed the model your content and kept your brand to yourself. Write it down instead: colors as hex codes with placement rules, fonts and their jobs, one line on the logo, two lines of voice, and a do-not list that kills the defaults. Paste that brief above every prompt, correct drift one line at a time, and reuse the same block across your whole project so everything matches. Then publish the results to live links on your own domain, and the brand holds from the first pixel to the URL.
