Yes. Unslop UI takes a screenshot after you paste a URL, flags recognizable visual AI-look patterns, and returns a score with specific fixes. Text detectors, builder checkers, and conversion graders answer different questions.

What does it mean when a website looks AI-generated?

You know the page: a near-black background, a violet-to-blue glow, a huge centered headline, two buttons, and three feature cards underneath. Scroll down and there's a bento grid with rounded corners, followed by another call to action.

None is automatically bad. Inter is a good font, and three cards may be the clearest layout.

Together, these repeated choices can make unrelated sites feel like the same starter template. That's the visual AI look—not proof of AI authorship.

A human-made site can look AI-generated, and an AI-built site can look distinctive. Ask: Which visible choices make my page feel generic?

Which tools can check my website, and what do they actually check?

“AI website detector” can refer to very different tools. Here's the comparison.

Free-tier details below were checked on each product's public homepage on 11 November 2026 (Asia/Singapore). They were not independently tested end to end.

Consider a page with bg-zinc-950, rounded-xl cards, and purple glows. A text detector won't assess its appearance. A builder checker looks for creation clues, not whether the design feels original. A conversion grader might focus on the headline and CTA instead.

What are the clearest signs of the AI website look?

Start with combinations that stand out in a screenshot.

Is the color palette doing too much work?

A familiar setup is #09090B (zinc-950) behind a gradient from #7C3AED (violet-600) to #2563EB (blue-600). In Tailwind, that's close to bg-gradient-to-r from-violet-600 to-blue-600.

Before: Every section has a purple glow, gradient text, and a luminous border.

After: Try a neutral background such as #FAFAF9, primary text in #18181B, and one accent reserved for the main CTA. You don't have to use those exact colors; the principle is to give each visual effect a job.

Does the hero follow the same template as everyone else's?

Before: A centered 56px headline, two equal-looking CTAs, and three cards labeled “Fast,” “Smart,” and “Easy.”

After: Try a left-aligned 48px (3rem at a 16px root size) headline next to an actual product screenshot. Give one CTA priority and replace the three generic cards with a real workflow: input, action, result.

Let the product determine the structure, not the template.

Are the fonts and components still on their defaults?

Inter and Geist aren't bad choices. Neither are shadcn components. But if every heading, card, modal, and button keeps the starter treatment, the page may feel familiar for reasons unrelated to your product.

Look for rounded-xl, rounded-2xl, text-zinc-400, border-zinc-800, and shadcn tokens such as --radius, --background, --primary, and --muted.

Before: Every section title is 36px bold; every card has a 16px radius; every paragraph is the same muted gray.

After: Try a deliberate hierarchy: hero at 48px with line-height: 1.1, section headings at 30px, and body copy at 17px with line-height: 1.6. Use cards only when a border or container helps readers compare information.

Adjust these example values to your content.

Are bento grids and generic claims hiding the product?

Bento layouts can organize different amounts of information well. But a bento grid full of abstract icons and vague promises tells visitors little about the actual experience.

Before: “Supercharge Your Workflow” above six shiny feature tiles.

After: “Turn a Meeting Recording into Searchable Notes” beside a relevant product view, if that is what your product really does.

Specific copy matters because a polished interface still feels generic when the words could describe any SaaS product.

How can I check my website and decide what to fix?

Review homepage screenshots at desktop width and around 375px on mobile. Look for repetition, not software fingerprints.

Use this checklist:

  • Hero: Is it the familiar centered headline, two CTAs, and three cards without a product-specific reason?
  • Colors: Are purple-blue gradients, dark glows, or glass effects repeated across sections?
  • Typography: Are Inter or Geist used everywhere without a clear type scale or hierarchy?
  • Components: Do rounded-xl cards, bento grids, and default shadcn styles dominate the page?
  • Copy: Could you replace the product name and keep the same claims?
  • Mobile: Does the layout still explain the product, or just collapse into a long stack of identical cards?

For a quicker first pass, a free URL-based visual scan can take the screenshot, flag specific AI-look tells, and provide a score with fixes. Treat the score as a diagnosis to examine, not as a verdict about who built the site.

Fix the most visible, repeated pattern first. One improved hero may beat a complete palette change.

How do I make my website look less AI-generated without a full redesign?

Work from the top of the page down.

Show the actual product. If you have a meaningful interface or output to show, use it instead of an abstract glowing illustration. A screenshot showing a real task can explain more than three feature cards.

Reduce decorative effects. Try removing one glow, one unnecessary gradient, and one layer of glassmorphism. Compare at the same viewport width. Aim for clearer emphasis.

Break the repeated layout. Don't force every section into grid-cols-3. A process might work better as three steps. A capability might need a large screenshot and one paragraph. A comparison may belong in a table.

Tighten the type system. Set readable body copy around 16–18px, check line length, and reserve strong weights for actual hierarchy. A consistent type system is more useful than changing fonts just to appear different.

Replace placeholder language. Explain the input, what happens, and the output. “Upload a CSV and find duplicate rows” gives readers more than “Make work smarter,” assuming that's truly what the product does.

Don't redesign a clear, useful page just to lower its AI-look score.

When should I use a different kind of website checker?

Use an AI text detector when your concern is written content. Use an AI-builder checker when you're investigating clues about how a site was constructed. Neither gives you a reliable judgment of visual originality.

Use a landing page grader when the goal is to improve messaging, CTAs, trust signals, or conversion-oriented structure. That review may overlap with visual design, but a high conversion grade doesn't necessarily mean your aesthetic is distinctive.

Use a visual AI-look review when your problem is that the site resembles familiar AI templates. The 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. It is a different scope from the free URL scan, not a promise that a design score predicts business results.

Can a score prove that AI designed my website?

No. A screenshot can show patterns, but not authorship. A human-built site can look templated, while an AI-assisted design can look original.

The useful outcome is a short list of visible choices to improve. If the recommendations make the site clearer, more specific, and more recognizable, the review has done its job—regardless of what the score says.

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

Is there a free tool to check if my website looks AI generated?

Yes. A free visual scan can review a URL screenshot for common AI-look patterns and show specific design fixes. That's different from asking whether the text or source code was generated by AI.

Can I paste my URL into a tool that scores my landing page design?

Yes, but check what the score represents. Some graders focus on conversion and trust; a visual AI-look score focuses on recognizable design patterns and their possible fixes.

Can I upload a screenshot and get an AI website design critique?

You can ask ChatGPT or Gemini to review an uploaded screenshot and give design feedback. Ask for concrete criteria—hierarchy, typography, color, repeated components, and mobile layout—rather than a vague “good or bad” rating. Unslop UI's free scan works from a URL, not a file upload.

How can I tell if a website was made with v0 or Lovable?

A builder-focused checker such as Is That Vibe Coded looks for fingerprints associated with AI website builders. Detection is best-effort, not proof of which tool made the site, and it doesn't establish whether the design looks generic.

Why does my website look AI-generated if I built it myself?

Designers and AI builders often start from the same fonts, component libraries, and layout conventions. The resemblance usually comes from the combination of visible choices, not from whether a human clicked the buttons.

Is there a free AI landing page roast tool that tells me exactly what to fix?

General roast tools can critique landing-page design or conversion, while an AI-look scan focuses on template-like visual patterns. Run a free URL scan at unslopui.org to identify the visible design tells worth reviewing first.
