Carlenius automatically remembers every vehicle you've seen while browsing car dealers, so you don't have to dig through your browser history.

Browse viewed and liked vehicles

Get a quick overview of every vehicle you've visited in a simple list view.

Automatic VIN detection

Need a quick VIN (Vehicle Identification Number) check? Dealers sometimes hide the VIN. Carlenius can detect it from hidden parts of the page or directly from the listing text.

Wide dealer coverage

Carlenius works with major US dealer sites as well as social networks such as Facebook Marketplace — and we keep expanding the range.

Monitor price changes

Carlenius remembers the last price it saw and shows you the difference, even when the website itself does not.
