Does your site look AI-made?
Paste your address. We open your homepage in a real browser and measure 39 things people call “AI-made”. Only 3 are far more common on pages built with an AI builder than on pages made by hand (Lucide icons in tiles, Tailwind default colours and preset shadows), so only those make your hand-made score out of 100. You see the rest too, with their numbers.
Free. About 20 seconds. Your result gets its own link to share; it is never listed anywhere.
What counts
3 defaults, each with its points.
A trait counts only if it is on at least 1 in 10 pages built with Lovable and at least twice as common there as in every group of hand-made pages, including 283 pages that design galleries picked in 2025-26. The bars show how often we found each one.
Lucide icons in tiles−45
Two or more Lucide icons (the icon set shadcn/ui installs by default), each in a matching tile, side by side.
Tailwind default colours−25
Two or more colours taken unchanged from Tailwind’s default palette (indigo-600, violet-500 and the like).
Preset shadows−13
Tailwind’s preset shadows (shadow-lg, shadow-xl) on two or more cards or panels.

Why most famous sites score high. What counts is a builder’s untouched defaults (Lucide icons in tiles, Tailwind default colours and preset shadows), and famous sites pick their own. The looks they share with AI-built pages, such as frosted glass, glow and gradient text, are not counted: see the table above for why.
Method
How the score is made.
“AI-made” here means one thing we can measure: how close a page looks to what AI site builders put on a page by default. Every page starts at 100. Each default found takes off its points, and the same default always takes the same points, so the score moves only when a finding comes or goes.
The points come from 558 homepages read the same way: 145 built with Lovable, and 413 made by hand in four groups that weigh the same: 157 SaaS pages and 126 small sites that design galleries picked in 2025-26, 32 famous sites, and 98 small sites from 2019-21 (read on the Internet Archive, before AI builders). 39 traits were measured; a trait counts only if it is on 10% or more of the Lovable-built pages and at least twice as common there as in each hand-made group. A logistic model then sets the points, so two traits that come together are not counted twice: 10 points means the odds of an AI-built page double.
Checked on pages it never saw (the rule and the points made again without them), it scores a Lovable-built page lower than a hand-made one 75% of the time: 75% against gallery SaaS pages 2025-26, 73% against gallery small sites 2025-26, 76% against famous sites, 79% against small sites 2019-21. On 16 pages built with Bolt, a builder it never learned from, 81%. Method of 6 Nov 2026; each check reads the homepage once, in a desktop window 1440 pixels wide.

What it is not
- Not a test of who built the page. A page made with AI can look hand-made, and a hand-made page can look like the default.
- Not a verdict on quality. Some of the best-designed sites on the board use these on purpose.
- Not about sales. There is no scientific evidence that looking AI-made affects conversion. It does not measure conversion, sign-ups or revenue.
Where the traits come from
- Anthropic’s frontend-design guidance for Claude (December 2025 version): names Inter and system fonts and purple gradients on white as generic AI-made looks.
- Impeccable, open-source design rules by Paul Bakaus: lists a coloured stripe down one side of a card, gradient text, cards inside cards, an icon tile above each heading, a pill above the hero headline and em-dash overuse as tells of generated pages.
- Tailwind UI’s stock hero section (archived December 2024): the template many builders learned from: a pill above the headline, a blurred colour shape behind it, indigo buttons, “Get started” next to “Learn more”.
- Tailwind CSS default theme: the exact default colours and shadows the check compares against.
- Bolt’s official starter instructions: Tailwind and Lucide icons by default, and Lucide icons for logos.
- shadcn/ui and Lucide: the component kit AI builders ship, with Lucide as its icon set and rounded cards.
- Wikipedia: Signs of AI writing: emoji at the start of headings; em dashes, now listed as a sign of older AI writing.
- Design Theater (arXiv, July 2026): 120 interfaces from five generative UI tools converge in look and layout; colour varies most.
- Design Creativity Bench (arXiv, October 2026): designs from AI models resemble each other more than human designs do. Neither study names traits; the traits here are tested on our own labelled pages.
What is known about looks and conversion
We looked for a study that compares pages that look AI-built with pages that do not and measures sign-ups or sales. We found none. The nearest:
- Thorshaug, Schjelderup and Papachristos, CHI 2026 (extended abstract): 43 people: trust in sites with AI-made images dropped once they were told the images were AI-made. About images and disclosure, not page design.
- Cicek, Gursoy and Lu, 2024: the words “artificial intelligence” in a product description lowered purchase intent. About wording, not looks.
- Tuch and others, 2012: familiar-looking, simple sites were rated more beautiful at first glance. If anything, the opposite direction.
Questions
What people ask about the score.
Is this the chance that AI made my page?
No. It measures how close the page looks to an AI builder’s defaults. A page made with AI can score high once someone changes the defaults, and a page written by hand can score low if it keeps them. The page’s own code is only named as a fact on the result (for example “the page’s own code names Lovable”), never used in the score.
Will a higher score get me more sign-ups?
There is no scientific evidence that looking AI-made affects conversion. We know of no study that measured it. What does measurably stop sign-ups (a hidden button, a missing price, a broken link) is what LandingBoost’s main scan checks.
Stripe and Linear use glow and glass. Is that AI?
No, and the check knows it. Frosted glass: 46% of Lovable-built pages, 34% of famous sites, so it does not count. Blurred glow: 44% of Lovable-built pages, 22% of famous sites, so it does not count. Gradient text: 32% of Lovable-built pages, 19% of famous sites, so it does not count. A trait counts only when it is at least twice as common on AI-built pages as in every hand-made group, today’s gallery picks included.
I wrote my site by hand with Tailwind. Why does it score low?
Because what AI builders ship is Tailwind, shadcn/ui and Lucide with their defaults untouched. The score is about the look, not about who typed the code: a page that keeps the default palette, corners and icon tiles looks like every other page that kept them.
Writers used em dashes long before ChatGPT.
True, and here they cost nothing. Five or more em dashes, one every 170 words or more often, are on 32% of Lovable-built pages but also on 17% of small sites picked by design galleries (2025-26): not twice as common, so they are not counted. Wikipedia’s guide to AI writing now lists them as a sign of older AI text.
Why trust your groups?
Every page in them is public and named by its source: Lovable’s showcase and *.lovable.app addresses; madewithbolt.com; saaslandingpage.com’s picks from August 2025 to November 2026; One Page Love’s newest landing-page and product picks; small sites from 2019-21 on the Internet Archive; 32 famous homepages. 0 gallery or archive pages whose code names Lovable, Bolt or v0 were taken out of the hand-made groups.
Can one small change swing the score?
Only by adding or removing a whole finding. Each trait is a yes or no with a stated threshold and always costs the same points; the most any one finding takes is 45.
Why not ask an AI to judge the page?
Because an opinion cannot be checked. Every finding here is a measurement of the page as a browser renders it, marked on a picture of your page, and every number on this page is reproduced from the labelled pages.
