Chrome extension
Check the car without leaving the ad
AI Plate Checker finds the number plate on the car ad you're viewing and shows the car's record right beside it. No copying the reg into another tab.
It runs in Chrome on a computer. Open this page there to add it, or use the free check on your phone.
How it works
Add it to Chrome
One click from the Chrome Web Store. No account.
Open a car ad
On AutoTrader, eBay, Gumtree, Facebook Marketplace, PistonHeads or Motors.co.uk.
Read the panel
The car's record appears beside the ad. Full check opens everything on our site.
What the panel shows
MOT history in one line
Tests, fails, the latest result and its advisories.
Repair estimate
What the latest MOT's faults and advisories are likely to cost.
Risk: Low, Medium or High
Read from the car's whole MOT record.
ULEZ
Compliant, not compliant, or check with TfL.
The numbers come from the same checks as the free check on our site.
Works on
Anywhere else, highlight a reg, right-click and choose Check with AI Plate Checker.
Your browsing stays yours
The extension reads only the ad you're viewing, to find the plate, and sends the plate to aiplatechecker.co.uk to look the car up. We don't keep the pages you browse. See the extension in our privacy policy.
