Slop Lab

Forensic website authenticity report

Is this website AI-generated, or did a human actually make it?

Paste a link. We fingerprint the default agent house style: the watermarks, the stock copy, the obligatory gradient. Then we hand you a brutally honest 0–100 slop score.

What we look for

Six dimensions of telltale sameness.

None of these are crimes on their own. Pile enough of them up with zero customisation, though, and the site starts to look like every other thing an agent shipped that week.

01signal

Builder watermarks

Site builders and no-code tools all leave fingerprints: meta tags, telltale asset paths, the badge nobody bothered to remove. The loudest signal there is.

02signal

Default stack

One framework, one CSS kit, one component library, one icon set, one font. The reflex an agent reaches for. Use it untouched and you wear the uniform.

03signal

The model's voice

A handful of verbs every model loves, the compulsive punctuation habit, and that one rhetorical move where nothing is ever just itself. Machines have a tell.

04signal

Structural clichés

Big hero, a row of three cards, a wall of glowing quotes, a plan table, one final call to action. The same skeleton, generated a million times over.

05signal

Visual defaults

The obligatory cool-toned gradient, the glass card, the heavy rounded corners. Comfortable, safe, and instantly recognisable.

06signal

Placeholder residue

Filler text nobody replaced, a sample email, a made-up name, a stock photo, the starter title still sitting in the tab. Nobody finished the job.

Enough theory. Go put a site under the microscope.
