You Can Spot an AI-Built Site in Two Seconds
Scroll any launch feed right now — Product Hunt, X, Hacker News — and you'll see the same website over and over again.
Dark hero section. Inter font. An indigo-to-purple gradient. A 3-column "features" grid with Heroicons. A wall of shadcn/ui cards. A "testimonials" section with three fake quotes. A CTA button that says "Get Started" in exactly the same shade of blue-500 everyone uses.
You're not imagining it. AI builders — Claude Code, Cursor, v0, Lovable, Bolt — have converged on an aesthetic. They pull from the same training data, default to the same libraries, and ship the same components. The output is fast and it works. It also has a signature you can identify from across the room.
If you're using AI to ship websites (and you should be — it's 2026, you'd be insane not to), the skill that separates your work from everyone else's is knowing how to hide the tells.
Here are the four that matter, and the four plugins that fix them.
Tell #1: The Font Is Inter
Inter is a great font. Rasmus Andersson made it free, and it's on 40% of new websites for a reason. That reason is also the problem: when every AI-built site uses the same typeface, yours looks like everyone else's.
The Fix: Pick a Real Typeface
Not from Google Fonts' top 10. Go to Fontshare (free, commercial use, zero BS), Pangram Pangram (some free, stunning quality), or Klim Type Foundry (paid, but the display fonts are worth it).
Specific recommendations that make AI-built sites instantly look hand-crafted:
Set it as your heading font and keep Inter or system-ui for body. The contrast alone rewrites how the page feels.
Tell #2: The Page Doesn't Move
AI builders generate static layouts. Scroll down, sections appear. Scroll up, sections disappear. That's it. No parallax, no scroll-linked animation, no elements that respond to where you are on the page.
Real websites in 2026 move. Not obnoxiously — subtly. Text that fades in as you scroll. Images that scale slightly as they enter view. Numbers that count up. Headlines that split into words and animate in one at a time.
The Fix: GSAP + ScrollTrigger
GSAP (GreenSock Animation Platform) is the animation library every agency uses. As of 2024, it's completely free — Webflow bought GreenSock and made the entire platform, including ScrollTrigger and SplitText, free for everyone. If you've been scared off by the old "Business Green" license, that's gone.
The 80/20 plugins from GSAP:
Drop GSAP into one hero section and one scroll-linked headline reveal. That's it. Your site now moves like it was built by a human who cares.
Tell #3: The Scroll Is Janky
Default browser scroll on macOS and iOS feels fine. On Windows and Linux, it's a staircase. And on any OS, AI-generated sites rarely bother with smooth-scrolling, scroll-snapping, or scroll-hijacking for dramatic sections.
This is a two-second upgrade that makes your site feel 10x more premium.
The Fix: Lenis
Lenis by Studio Freight is a tiny smooth-scroll library (2KB gzipped) that replaces native scroll with buttery interpolated scrolling. It's what every award-winning Awwwards site uses. Import it, init it in a useEffect, done. The entire integration is about five lines — create the instance, hook it into requestAnimationFrame, and your whole site now scrolls like Apple's product pages.
Bonus: Lenis plays nicely with GSAP ScrollTrigger out of the box. Combine them and you get buttery scroll PLUS scroll-linked animation — the one-two punch that instantly kills the AI-builder look.
Tell #4: The Icons Are Heroicons (or Emoji)
Look at any AI-generated landing page. Every feature box has either a Heroicons outline icon or — worse — a raw emoji pretending to be an icon. ⚡ for speed. 🔒 for security. 🎨 for design. You've seen it 10,000 times this week alone.
Heroicons aren't bad. They're just everywhere, which means using them tells everyone you didn't bother to commission, draw, or even *pick* icons.
The Fix: Rive (or, If You're Lazy, Lucide + Custom Stroke)
Rive is the 2026 replacement for Lottie. It's an interactive vector animation tool — you design once, export a tiny runtime file, and the animations respond to hover, scroll, state changes, anything. Rive animations can literally animate *in response to* mouse position or state, in real time, at ~5KB each.
Browse the Rive Community — there are thousands of free animated icons, characters, and illustrations you can drop into a site in minutes. The ones that look good look *really* good, and nobody else is using them because the AI tools don't know they exist yet.
If you want a simpler lift: use Lucide (the open-source Feather fork) with a custom stroke width (1.5 instead of the default 2), a custom color from your palette, and a subtle hover animation. Two changes and the icons stop looking stock.
The Meta-Skill: Taste
Here's the honest part. Plugins don't save you. I've seen GSAP used to make websites worse. I've seen Rive animations that looked like screensavers from 2003. I've seen custom fonts that crashed with every other design decision on the page.
The real skill is taste. Knowing when to add motion and when to stop. Knowing which three features of GSAP matter and ignoring the other 47. Knowing that a great typeface paired with a bad color palette looks worse than Inter would have.
AI builders nail the 80% that used to take a week. The 20% they miss — the taste, the restraint, the deliberate imperfection — is where craft lives, and it's why hand-crafted sites will always have a premium over AI-built ones.
Use AI to ship the scaffolding. Use these four plugins to add the signature. And use your own judgment to know when to stop.
Quick Recap
Total investment: a half-day. Return: your AI-built site stops looking AI-built.
One Last Thing
If you're shipping sites fast with AI and need to batch-convert assets along the way — SVG icons for the web, optimized PNGs for hero images, PDFs of your landing pages for investor decks — FluidConvert's tools handle the grunt work so you can spend your time on the parts that actually make your site look crafted.
The future belongs to people who can combine AI speed with human taste. The plugins above are just the vocabulary. You're the one who still has to write the sentences.
