AT Companion

AI-powered analysis for AutoTrader listings. Instantly highlights service history, MOT, HPI status and more.

AT Companion adds instant AI-powered analysis to every AutoTrader UK listing, so you can spot great deals — and avoid bad ones — without clicking through dozens of tabs. ────────────────────────────────── HOW IT WORKS ────────────────────────────────── Install the extension, browse AutoTrader UK as normal, and AT Companion works automatically in the background. A sidebar panel slides in from the right of the page, showing a full breakdown of every listing you're viewing. No account needed to get started. ────────────────────────────────── FEATURES ────────────────────────────────── ✦ SERVICE HISTORY Full, partial, or missing — flagged instantly on every listing card across your search results. ✦ MOT STATUS See exactly when the MOT expires, including upcoming deadlines buried in the seller description. ✦ HPI FLAG DETECTION Potential outstanding finance, write-off history, or plate changes are highlighted before you waste your time. ✦ PRICE VS MARKET Understand whether a listing is priced fairly against comparable cars — no manual tab-comparing required. ✦ TRAFFIC LIGHT RATING Every listing gets a green, amber, or red signal summarising the overall picture at a glance. Scan an entire page of results in seconds. ✦ HIDE SPONSORED ADS Remove promoted and featured listings from search results with a single toggle. See genuine matches only. ✦ PERSISTENT SIDEBAR The analysis panel stays open as you scroll through results. No clicking in and out — just browse and decide. ────────────────────────────────── NOTES ────────────────────────────────── • Works on AutoTrader UK (autotrader.co.uk) only • Not affiliated with or endorsed by AutoTrader Group plc • AI analysis is based on information visible in each listing — it does not perform a paid HPI check • Requires Chrome or a Chromium-based browser (Edge, Brave)
