How to make a Lovable app not look AI-generated (a tell-by-tell audit)

People don't spot a Lovable app because of one thing. They spot six or seven small defaults stacked together. Here's how to find them on your own site and remove them one prompt at a time.

Updated 2026-10-25 · 6 min read · by the Unslop Me team

Lovable is good at building working apps fast. What it hands you on the first pass is the average of every React + Tailwind + shadcn/ui site the model has seen. That average is easy to recognise: a gradient hero, Inter everywhere, a row of identical icon cards, frosted panels, and a small "Edit with Lovable" badge in the corner.

This guide is an audit, not a redesign tutorial. (For the full prompt-by-prompt redesign, see how to make a Lovable app look professional.) Work through the tells below in order. They're the same checks our Slop Score scanner runs, listed with the points each one costs.

How the Slop Score works, briefly

Every site starts at 100, which means it looks designed. Each tell we detect subtracts up to its weight, and the score can't go below 0. If you already use custom typography and no stock Tailwind palette, deductions are multiplied by 0.6, because the rest of the page reads as intentional. 60+ already looks designed, 35–59 has a few giveaways, and under 35 has lots of room to improve.

What we see on Lovable sites

The public Slop Leaderboard includes 12 Lovable showcase apps (as of 2026-10-17). They average 50 (median 48). Five already score 60+ and four are under 35. So a Lovable app can look designed. The ones that do just overrode more defaults. In 6 of those 12, the builder badge is one of the two biggest tells listed. It's also the easiest tell to fix.

The audit, cheapest fix first

1. The "Edit with Lovable" badge (up to −10)

It's free advertising for Lovable and a cue to the visitor to start looking for the other tells. Turn it off in your project settings if your plan allows it, or ask Lovable to remove it. Then check the published URL in a private window, because your logged-in view can differ.

2. Emoji standing in for icons (up to −12)

🚀 Fast. ⚡ Powerful. 🔒 Secure. We flag two or more emoji used as icons in headings, cards or buttons. Lovable often adds them to feature lists and empty states.

Remove every emoji used as an icon in headings, cards, buttons and lists.
Where an icon genuinely helps, use one consistent icon set at one size.
Otherwise use no icon. Do not change any text or functionality.

3. Inter or system fonts for everything (up to −12)

We flag pages where over 90% of the text is set in Inter, system-ui, Geist, Poppins, DM Sans, Manrope or similar defaults. Swapping fonts is the cheapest big change you can make, because it touches every line on the page.

Change typography only. Load "Fraunces" (headings) and "Inter Tight" (body)
from Google Fonts. Use Fraunces for h1–h3, Inter Tight for everything else.
Make the h1 at least 3.5x the body size on desktop. Do not change layout.

4. Purple/indigo gradient (up to −20, the heaviest tell)

Any background gradient with purple, indigo or violet hues. This is the single biggest deduction we make, and it's the one people notice first. On the leaderboard, every app with a purple gradient among its top two tells scored 50 or below.

Replace all purple/indigo/violet gradients with flat surfaces.
Background: #F4F0E8. Text: #16130F. One accent: #FF4D1C, used only
for the primary button and links. No gradients anywhere.

Swap in your own five colours. Here are eight palettes that don't read as default.

5. The stock Tailwind palette (up to −14)

Three or more stock Tailwind colours (indigo-500, slate-900, gray-50…) or heavy purple accents. Removing the gradient doesn't remove this tell. You need named tokens.

Define CSS variables --bg, --surface, --ink, --muted, --accent with the
hex values above and replace every stock Tailwind colour class with them.

6. Glassmorphism (up to −10)

Any surface using backdrop-filter: blur(). Lovable likes frosted navbars and cards. Ask for "solid surfaces with a 1.5px border, no backdrop blur anywhere".

7. The uniform icon-card grid (up to −12)

Rows of 3, 4 or 6 identical cards, each with an icon and a heading. This is the hardest tell to prompt away, because it's a content decision. Pick your one most important feature, give it a screenshot and half the width, and turn the rest into a plain list.

8. rounded-2xl on everything (up to −8)

We flag pages where more than 45% of boxed elements have a radius of 12px or more. Pick one radius (2–4px works well) and ask Lovable to apply it to buttons, cards, inputs and images.

9. Default Lucide icons (up to −8)

Four or more stroke-2, 24px Lucide-style SVGs. It's the most common tell on the whole leaderboard, showing up on 77% of the sites. Use far fewer icons, or a set with a different weight.

10. Centered hero and a flat type scale (up to −6 each)

If the h1 is text-align:center, that's a tell. So is an h1 less than 2.6x the body size. Left-align the hero, put the product screenshot beside it, and make the headline big.

11. Generic AI copy (up to −16)

Unlock, supercharge, seamless, elevate, empower, effortless, revolutionize, all-in-one, "in seconds". Rewrite the headline, subhead and buttons yourself: say what it does and who it's for. More in landing page copy that doesn't sound AI-written.

12. Mobile horizontal overflow (up to −8)

If the page is wider than a 390px phone, the whole thing wiggles sideways. Open your published URL on a phone, or in DevTools at 390px, and ask Lovable to fix whichever element overflows.

Order matters: one prompt per tell

Don't paste all of this at once. Lovable handles one focused, styling-only change better than a giant redesign prompt, and a narrow prompt is easier to roll back. A good order is: badge, emoji, fonts, colours, glass, radius, hero, grid, copy, mobile. Re-scan after the fonts and colours. Those two usually move the score the most, because they touch every element.

Check your work

Run your published URL through the free scanner before and after. Each tell comes with the evidence we found (the class name, the font stack, the word), so you can confirm a fix actually landed rather than guessing.
