    Traces AI builders leave

    AI site builders leave telltale traces in the sites they make. We know the traces of 53, among them Lovable, Bolt.new and v0, and show each one we find.

  • Our reading

    Only clear signs count

    One weak hint never makes a site “AI-built”. Weak hints count only together, and we say what they add up to.

    Builders with AI features

    Figma Sites, GoDaddy Website Builder (Airo), Framer, Wix and others also offer AI. We name them, but we can’t tell whether their AI was used.

Honest limits

What it can’t tell

  • We test it on 2,312 sites whose makers we know; it misses some AI-built sites, and we publish what it gets wrong.
  • Sites written with coding assistants such as Cursor, Claude Code or Copilot usually leave no traces in the code.
  • A site rebuilt by hand after an AI first draft may keep none.
  • Builders change over time; we update what we look for and log every change.
  • We don’t judge the writing itself, only the traces the builder left.
