Rex. Your senior tech in the passenger seat.

Rex is the AI diagnostic agent from RevMind LLC for mobile mechanics and independent techs. It reads the car live from a Bluetooth OBD-II adapter you already own (about $40). No $1,000+ scan tool. No shop required.

One account works on your phone, tablet, or computer. Rex works the fault with you from live data, stored codes, and session history, then you can send the quote from the driveway.

Pro adds job tracking: customers, vehicles, repair orders, and appointments. Rex only is live diagnostics with no job tracking.
