AI-powered listing comparison · v1.1

Normalise listings.
Compare. Decide.

ACC, Adaptive Cruise or Driving Assistant — whatever the dealer calls it, here it becomes the same row. Collect listings while browsing via browser button, URL or text paste.

Bookmarklet is linked to workspace "Mein Vergleich" — listings land there.
Browser button · the real game-changer

Save while browsing.
One click. No copy-paste.

Drag the button on the right into your bookmarks bar. On any listing — mobile.de, AutoScout24, eBay Kleinanzeigen, Pkw.de — just click it: the listing is captured automatically, AI extracts the specs, normalises equipment and warns about weak spots right away.

  • Works on any portal — even mobile.de (bypasses Akamai because your own browser loads the page)
  • Inline toast right on the listing: Score + top warnings visible instantly
  • Images are picked up automatically (vision analysis)
