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.

1. Sitepeel AI slop checker
Scores a page from 0 to 100 on the tells of AI-made design, marks each one on the page with its evidence, and writes a fix prompt from a score of 40. Builder traces, like a Lovable badge, show separately.
- It measures the design, not who made it
2. aiwebsitedetector.com
Looks for the fingerprints of 50+ AI and no-code builders, like Lovable, Bolt and Framer, and lists the tech stack. Recent scans show in a public feed on its page.
3. aiwebsitedetector.net
Scores how likely a site was built with AI and shows the evidence for each signal. It says it can’t spot sites made with local agents like Claude Code unless a trace leaks into the page.
4. Sitepeel tech stack checker
If you only want the site builder (Webflow, Framer, Wix, Shopify), the free tech stack checker shows it with the evidence it found.
Which one should you pick?
Questions
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.
