See if a used-car listing is a good deal, then start Autopilot. Controlled beta — verify rare trims. See if a used-car listing is a good deal without leaving the page — then start Autopilot to negotiate it. Cartoru reads the listing you’re looking at, compares it to live similar inventory, and shows directional fair-value context right on the page. Sign in to start Autopilot from the overlay: it contacts the dealer by email and SMS, counters from the comps, and taps you when it’s time to sign. HOW IT WORKS 1. Open a listing on a supported site. 2. The Cartoru overlay analyzes year, make, model, trim, price, and mileage against nearby comps. 3. You’ll see a deal read (great / fair / high, or inconclusive), expected price context, and comparable listings. 4. Sign in to start Autopilot from the same overlay, or open the full analysis on cartoru.com. SUPPORTED SITES • AutoTrader • CarGurus • Cars.com • Craigslist WHY INSTALL • Instant deal context while you browse — no copy-paste of URLs • Ranked comps and a fair-value range for negotiation • Autopilot outreach from the listing, using that analysis • Same account as cartoru.com (Google or email sign-in) CONTROLLED BETA Cartoru is in a controlled beta. Results are directional pricing guidance for negotiation, not a formal appraisal, certified valuation, or guarantee you’ll get a specific price. On exotic, luxury, and rare-trim cars, always verify trim, options, and condition yourself — numbers can be off when comps are thin. PRIVACY The extension only runs on supported listing sites and cartoru.com. It reads the visible listing page to extract vehicle details, then sends those fields to Cartoru’s API. It does not read your full browsing history. Sign-in stays in your browser so the overlay can stay logged in.
