What makes a website look AI-generated?

A website looks AI-generated when it combines familiar design patterns without making choices specific to the product or audience. The biggest giveaways are purple-blue gradients, centered hero sections, three identical feature cards, default fonts, bento grids, and vague marketing copy. None of these proves AI was used, but when several appear together, a website can feel generic, cheap, or interchangeable.

The problem isn't that AI makes ugly websites. It often makes clean, attractive ones.

The problem is that too many of them look the same.

If your friends say your website looks AI-generated, they're probably reacting to predictable design decisions rather than identifying the technology behind it.

Here are 20 common tells, why AI website builders tend to produce them, and what you can change.

What visual effects make a website look AI-generated?

1. The purple-to-blue gradient

What it looks like: A hero background blending violet (#7C3AED) into blue (#2563EB), often repeated on buttons and headings.

Why AI uses it: It's a safe shortcut for making almost any software product look technical.

Fix: Try an off-white background (#F7F5F0), charcoal text (#252722), and one accent color (#B46F4D). #252722 on #F7F5F0 is about 13.85:1 contrast, which passes WCAG AA for body text. Do not use #B46F4D for small body text on that background (about 3.6:1). Use gradients only when they serve a purpose.

2. Glowing dark-mode backgrounds

What it looks like: Black backgrounds with neon purple, cyan glows, and illuminated card borders.

Why AI uses it: Glow effects create a futuristic look without much product-specific design.

Fix: Replace glow effects with a solid #111827 background, #F9FAFB text, and subtle 1px borders in #6B7280. #F9FAFB on #111827 is about 17:1, which passes WCAG AA for body text. #6B7280 meets the 3:1 contrast expected for UI borders; the more common gray #374151 is only about 1.7:1 on this background and is too dark.

3. Floating 3D blobs and glassmorphism

What it looks like: Abstract spheres, frosted panels, and floating geometric shapes surrounding the headline.

Why AI uses it: Decorative objects fill space when there is no meaningful product imagery.

Fix: Replace abstract artwork with a real product screenshot or workflow diagram. Remove backdrop-blur-xl from cards where transparency adds nothing useful.

4. Generic stock photos

What it looks like: Smiling office workers, anonymous people using laptops, or futuristic illustrations unrelated to the product.

Why AI uses it: Generic imagery can fit almost any business description.

Fix: Show the actual interface, a product interaction, or a real example of the output. If you have no useful image, a strong text-only hero is better than unrelated photography.

5. Lucide icons on every card

What it looks like: Sparkles, lightning bolts, shields, and arrows inside identical rounded squares.

Why AI uses it: Common icon libraries make feature sections easy to generate.

Fix: Remove icons that don't communicate meaning. Replace generic symbols with small product screenshots, numbered steps, or simple text headings.

Which landing page layouts are dead giveaways?

6. The centered hero with three feature cards

What it looks like: A pill badge, centered headline, short subtitle, two buttons, and exactly three cards underneath.

Why AI uses it: The formula can be reused for almost any SaaS landing page.

Fix: Try a split hero with 45% of the width for text and 55% for a product preview. Use a left-aligned heading with max-width: 620px.

7. A bento grid without a clear purpose

What it looks like: Feature cards of different sizes filled with random icons, charts, and gradients.

Why AI uses it: Bento layouts make ordinary features look more elaborate than they are.

Fix: Give the most important feature the largest area. If every feature has equal importance, use a simpler grid-cols-1 md:grid-cols-2 layout instead.

8. Everything is inside rounded cards

What it looks like: Features, testimonials, statistics, and paragraphs all enclosed in identical boxes.

Why AI uses it: Reusable components keep layouts consistent with little effort.

Fix: Remove unnecessary card containers. Use whitespace and thin dividers instead. In shadcn, customize the --radius token rather than accepting the same corner treatment everywhere.

9. Every page follows the same section order

What it looks like: Hero → logos → features → testimonials → pricing → FAQ → CTA.

Why AI uses it: It's a familiar template that doesn't require much understanding of the buyer.

Fix: Organize the page around real customer questions—for example, problem, product demonstration, how it works, limitations, then pricing. Don't include a section just because templates usually have one.

Which typography choices make a website feel generic?

10. Default Inter or Geist everywhere

What it looks like: Clean sans-serif typography that feels identical to countless other software websites.

Why AI uses it: Inter, Geist, and Roboto are versatile defaults in common starter templates.

Fix: Choose type intentionally. Try Fraunces headings with Source Sans 3 body text, or IBM Plex Sans for a technical interface—alternatives, not automatically better fonts.

11. Every heading looks equally important

What it looks like: Bold hero text, bold section headings, bold card titles, and bold buttons competing for attention.

Why AI uses it: Applying one bold style everywhere is easier than building a real hierarchy.

Fix: Set a type scale: hero 56px/1.1, section headings 32px/1.2, card titles 20px/1.3, and body text 16px/1.6. Adjust the scale on mobile.

12. Long paragraphs with poor line lengths

What it looks like: Text stretching across the screen or cramped descriptions inside narrow cards.

Why AI uses it: Generated layouts often prioritize reusable containers over reading comfort.

Fix: Limit paragraph width to roughly 65ch using Tailwind's max-w-[65ch]. Use leading-7 for body text and shorten supporting descriptions.

13. Every section has identical spacing

What it looks like: Uniform gaps, padding, and section heights that make the entire page feel mechanical.

Why AI uses it: The same spacing tokens are easy to repeat automatically.

Fix: Establish deliberate spacing relationships. Try space-y-4 within text groups, gap-8 between cards, and py-24 for major desktop sections. Give important demonstrations more room.

What landing page copy makes a website feel AI-generated?

14. Headlines that could describe any company

What it looks like: "The Future of Digital Productivity" or "Transform the Way You Work."

Why AI uses it: Broad claims sound professional without requiring product knowledge.

Fix: Describe a specific outcome.

Before: "A Smarter Way to Manage Everything."

After: "Track client invoices and see which payments are overdue."

15. Buzzwords instead of useful explanations

What it looks like: Phrases such as "supercharge your workflow" or "next-generation productivity."

Why AI uses it: Generic benefits are easy to write and hard to disprove.

Fix: Explain what visitors can actually do.

Before: "Supercharge your creative workflow."

After: "Upload a photo, compare the results, and download the version you prefer."

16. Every button says "Get Started"

What it looks like: Repeated buttons labeled "Get Started," "Learn More," or "Explore Now."

Why AI uses it: Generic CTA labels can be reused on almost any template.

Fix: Match the button to its destination. Use "Try the Demo," "View Pricing," or "See an Example" when those describe the actual next step.

What polish and trust issues make a website look cheap?

17. Fake-looking testimonials and logos

What it looks like: Anonymous five-star reviews, generic customer quotes, or impressive logo strips without context.

Why AI uses it: Social proof is a standard section, even when genuine evidence is unavailable.

Fix: Remove unsupported testimonials and logos. Use authentic, authorized reviews when available. Until then, show product examples or explain the functionality clearly.

18. Dead buttons and placeholder content

What it looks like: Links with href="#", nonfunctional buttons, or leftover lorem ipsum.

Why AI uses it: A generated interface can look complete before its interactions work.

Fix: Click every visible control. Replace placeholder links with working destinations, or remove them. A smaller working website is more convincing than an elaborate mockup.

19. A broken mobile layout

What it looks like: Cut-off headings, overflowing cards, tiny buttons, or desktop navigation squeezed onto a phone.

Why AI uses it: A generated responsive layout may not have been tested.

Fix: Manually check 375px, 390px, and 430px viewport widths. Use max-w-full for images, responsive grid classes, and appropriate mobile padding. Test menus and dialogs too.

20. Decorative animation everywhere

What it looks like: Floating cards, pulsing buttons, animated gradients, and constantly moving backgrounds.

Why AI uses it: Motion makes a simple design look more elaborate.

Fix: Remove animation that doesn't explain an interaction. Use short transitions around 150–200ms for useful state changes, and support prefers-reduced-motion.

How can I check whether my website looks like an AI template?

Try the company-name swap test.

Replace your company name with a competitor's name. Read the headline, features, benefits, and descriptions again.

If most of the page still makes sense, it probably isn't communicating what makes the product different.

Then use this checklist:

• The headline explains what the product actually does.
• Colors and typography feel deliberately chosen.
• Images demonstrate real functionality.
• The layout follows the content, not a template.
• Buttons describe specific actions.
• Testimonials and claims are genuine.
• Links and interactive elements work.
• Mobile layouts have been tested.
• Decorative effects serve a purpose.
• Competitors couldn't reuse the page without major changes.

You don't need to eliminate all 20 tells. Look for the patterns that repeat most often.

If identifying those patterns is difficult, Unslop UI offers a free scan: paste your website URL, and it captures a screenshot, flags specific AI-look tells, provides a score, and suggests what to fix. A paid option adds a deeper AI design review and redesign direction, priced at $4.99 for one redesign, $9.99 for 3, or $19.99 for 10.

Can AI detectors tell whether my website looks AI-generated?

No. Text detectors, builder checkers, and conversion graders answer different questions from a visual AI-look review.

A visual AI-look score doesn't prove how a website was built. A human designer can create a generic page, and someone using AI can create a distinctive one. What matters is whether the finished design communicates something specific and useful.

For a side-by-side comparison of those tool categories, including free-tier details, see the separate guide "Is There a Tool to Check If My Website Looks AI Generated?"

How do I make my website look less AI-generated without starting over?

Start with the hero: a specific headline, fewer decorative gradients, and a real product view. Then tighten typography, drop repetitive cards, and replace vague benefits with concrete explanations. Check mobile layouts and every link before you stop.

The goal isn't less polish. It's making every choice feel connected to the product instead of a default template.

FAQ: What else do people ask about AI-looking websites?

What are the dead giveaways that a landing page was built by AI?

Common visual giveaways include purple-blue gradients, centered hero sections, identical feature cards, bento grids, default fonts, and generic marketing copy. These suggest a familiar design template, but they cannot prove AI created the website.

My friends say my website looks AI-generated. What do they actually mean?

They probably mean your website feels generic, predictable, or interchangeable with other websites. The issue is usually a combination of familiar layouts, weak brand personality, and copy that doesn't explain what makes your product different.

Why does my website look so cheap and generic?

A website can look cheap when it relies on stock imagery, repetitive cards, weak typography, inconsistent hierarchy, or unsupported social proof. Clean design alone isn't enough; the page needs meaningful visual choices and credible details.

Does using Inter or shadcn make my website look AI-generated?

No. Both are useful tools for building professional interfaces. The generic impression comes from combining unchanged defaults with common layouts, repetitive components, and little product-specific customization.

Can people tell if I used Lovable or v0 just by looking at my website?

Not reliably. Some generated websites share recognizable visual conventions, but those same patterns appear in human-designed templates. Visual appearance alone isn't dependable evidence of which tool was used.

How can I make my AI-generated website look more professional?

Replace vague headlines with specific product explanations, use meaningful imagery, establish stronger typography, and remove unnecessary decorative effects. Make sure every interaction works and the mobile experience feels deliberately designed.
