FAQ
Questions people ask
More free checks:
How can you tell if a website was made with AI?
AI website builders leave fingerprints: hosting addresses, build files, script names and markup patterns. The checker compares a site's public code against signatures for Lovable, Bolt, v0, Durable and 10Web, and platforms such as Wix, Framer, Webflow, WordPress and Shopify, and shows the evidence it matched.
Does this detect AI-written text?
No. It identifies the tool used to build the website, not who or what wrote the words. Text detectors are unreliable on short marketing copy and can wrongly flag human writing.
Why does it say no builder was found?
The site may be hand-coded, built on a custom framework, exported and re-hosted, or made with a tool we do not track yet. No match is not proof either way.
Is an AI-built website a problem?
Not by itself. What matters is whether it loads fast, can be found, is accessible and gets customers to act. The free Clunky scan checks exactly that.
