Free website tool for this task: [AI slop checker](https://sitepeel.dev/free-tools/ai-slop-checker/index.md) (https://sitepeel.dev/free-tools/ai-slop-checker/)

## In short

- How generic the design looks, with fixes: Sitepeel’s AI slop checker
- Which AI or no-code builder made it: aiwebsitedetector.com
- No tool can prove who, or what, built a site

## The short list

A builder leaves traces (a Lovable badge, Framer files). A generic design leaves tells (stock fonts, glowing cards, filler copy). Pick the tool for the question you’re asking.

## 4. Sitepeel tech stack checker

## Which one should you pick?

**Verdict:** To see if a page looks AI-made, and how to fix it: Sitepeel’s AI slop checker. To name the builder: aiwebsitedetector.com or Sitepeel’s tech stack checker.

## Questions and answers

### Can you tell if a website was made with AI?

Not for certain. Tools can spot a builder’s traces or generic design choices, but people make generic sites too, and AI can make careful ones.

### Is the AI slop checker free?

Yes. Sitepeel’s AI slop checker is free, with no sign-in and no install.

### Do AI text detectors work on websites?

They judge writing, not design or code. To check a website’s design, use a tool that reads the page, like the ones above.
