What is IsThisSiteAI?
The sharpest eye on
the modern web.
We built the tool we always wished existed — one that tells you exactly how a site was made, not just that it was.
AI Builder Detection
DetectionIdentifies sites made with Framer AI, Wix ADI, Hostinger AI, Dora, v0, Bolt, Lovable, and more. Our signature database grows weekly.
Deep Code Fingerprinting
AnalysisAnalyzes HTML structure, CSS naming patterns, meta tags, font stacks, and deployment headers for unmistakable AI signatures.
Visual Pattern Recognition
VisualSpots common AI design tells — identical spacing rhythms, default placeholder text, cookie-cutter section layouts.
Confidence Scoring
ScoreA clear 0–100 score built from dozens of corroborating signals. Not a guess — a grounded, explainable result.
Framework Detection
TechIdentifies Next.js, React, Tailwind, shadcn/ui, and hosting platforms commonly bundled by AI site builders.

Average scan time
I checked a competitor's site and the score came back 94%. Suddenly it all made sense — the layouts, the placeholder copy, all of it. Game-changing tool.
Mira Santos
Brand Designer
As a developer, I use this to do due diligence on freelance clients who say they 'built' their site. It's surprisingly accurate and the breakdown is thorough.
James Okafor
Freelance Developer
The improvement tips on Pro actually helped me clean up my Framer site so it stopped feeling generic. Worth every penny of the $9.
Theo Lindqvist
Indie Maker
Clean, fast, and honest. No dramatic AI doom — just a clear score and explanation. Exactly what I needed for a client audit.
Priya Mehta
UX Consultant
Detected that a vendor's portfolio was 100% AI-generated within seconds. Saved me from making a bad hire.
Carlos Ruiz
Startup Founder
The fingerprint breakdown is genuinely impressive. It doesn't just say 'AI' — it tells you which tool, which signals, and why. That level of detail is rare.
