What is AI slop?
AI slop is low-effort, mass-produced content generated by AI and published with little or no human review. The word that matters in that definition isn't "AI"; it's "low-effort". Slop is what happens when generating something became so cheap that checking it started to feel expensive.
Slop is to AI what spam is to email
Email didn't create junk mail; it made junk mail free to send, and spam was born. AI didn't create lazy content; it made lazy content free to produce, and slop was born. The term grew out of internet forums and took off in 2024, when generated articles, images and entire websites started flooding feeds faster than anyone could read them. People needed a word for "technically content, but nobody was home when it was made", and slop fit.
Text slop
Articles, product descriptions and social posts generated in bulk and published unread. The tells: buzzwords doing the work of ideas ('elevate', 'seamless', 'unlock'), sentences that could describe anything, and confident claims with no specifics behind them.
Image and video slop
The six-fingered hands, the melting text, the uncanny stock-photo people who don't exist. Generated visuals flooding feeds because producing a thousand of them costs less than licensing one real photograph.
Website slop
Entire sites generated by prompt and deployed unedited: the same gradient hero, the same three feature cards, the same default components, sometimes with 'lorem ipsum' still in the footer. This is the kind Slopdar measures.
What slop is not
Slop is not "anything made with AI". A developer who drafts with AI, then rewrites the copy, swaps the default components, and deletes the generic sections has made a website; the tool is invisible because the craftsmanship hid it. The same output shipped straight from the chat window is slop. The dividing line is whether a human made decisions after the machine stopped. That's also why calling something slop is an accusation about effort, not about tools.
How to spot website slop
Slop websites give themselves away through consistent tells: builder fingerprints left in the source code, untouched default component stacks, AI writing patterns in the copy, leftover placeholders, and the same template layout every time. We keep a full checklist in how to tell if a website is AI-generated, with instructions for checking each sign by hand. Most of them come from vibe coding left unedited: the tools aren't the problem, but their defaults are loud.
Measuring it: the Slop Score
Slopdar turns this definition into a number: paste a URL and ~50 weighted checks estimate how much a site looks vibe-coded or AI-generated, from 0 (Hand-Crafted) to 100 (Pure Slop), with the evidence listed so you can argue with it. It's signals, not proof: a high score means the site looks templated, not that no human was ever involved. Here's exactly how the scoring works.
