Paste any URL. In under 5 seconds you get a confident answer: which AI builder, CMS, or framework powers the site — and exactly why we think so.
The web is being rebuilt with AI. Builders like Framer, Lovable, Durable, and Bolt are changing how people create online — but identifying which tool was used from the outside is surprisingly hard. BuiltWith tells you the stack. We tell you if AI built it.
AI Website Detector gives you the full picture: what builder it uses, what AI tools it runs, how confident we are, what technology it's built on, and where it's hosted. No signup, no cost, no catch.

We fetch the page and scan script tags, CSS classes, and inline code for builder-specific fingerprints.
CDN hostnames (e.g. assets.framer.com) and HTTP response headers reveal the underlying platform.
Generator meta tags, data attributes, and class name patterns confirm the builder with high precision.
Signals are weighted and combined into a 0–99% confidence score so you know how certain the result is.
