Rex - AI Mechanic

Bluetooth OBD scanner + Rex, the AI mechanic that explains your codes clearly.

Turn a any Bluetooth OBD adapter (~$40) and your phone or tablet into a full diagnostic toolkit — in a multi-bay shop, on a mobile truck, or in your own driveway.

Connect an adapter, pull live data and trouble codes, and meet Rex: an AI mechanic that's grounded in YOUR vehicle's actual sensor readings and fault codes — not generic forum guesses — and turns them into a clear, ranked plan with the evidence behind every recommendation.

WHY REX AI MECHANIC
• Rex explains the "why," not just the code — grounded in live data, DTCs, and that vehicle's own repair history
• Every AI answer is transparent about its confidence and the evidence behind it
• No $5,000 proprietary scan tool — works with an off-the-shelf Bluetooth OBD-II adapter
• One record follows the vehicle: sessions, codes, and fixes stay attached to it, not trapped in a single scan

WHAT YOU GET
• Live data: fuel trims, O2 sensors, battery voltage, freeze frame, and more
• Full DTC (check-engine-light) workflow with history that stays with the vehicle
• Rex AI chat: ask questions, get a ranked diagnosis with confidence scores and next-check suggestions
• Camera VIN scan + NHTSA recall lookup
• Session records you can reuse at the bay, on a driveway, or at the counter
• Guided specialty tools (e.g. throttle position relearn) with pass/fail readouts

BUILT FOR
• Auto repair shops and technicians who need faster, more consistent bay diagnostics
• Mobile mechanics and owner-operators who need pro-grade tools on the road
• Car owners and DIY enthusiasts who want real answers instead of guessing at a check-engine light

Rex is not a generic chatbot bolted onto a scan tool — it rides along with you, calm and methodical, tied to the data on the vehicle in front of you right now.

AI-generated diagnoses and repair suggestions are a starting point, not a substitute for a qualified mechanic.
