Store description excerpt
Lewis connects to your car through any supported Bluetooth OBD2 adapter and tells you exactly what's going on under the hood: in plain English, not confusing codes. SCAN YOUR CHECK ENGINE LIGHT IN SECONDS Plug in your OBD2 adapter, tap Scan, and Lewis reads every diagnostic trouble code your car is throwing. No more guessing what P0301 means or whether it's safe to keep driving. Lewis breaks it down: what's wrong, how serious it is, and what to do about it. AI-POWERED DIAGNOSTICS Lewis doesn't just read codes — he understands them. Using advanced AI, Lewis analyzes your scan results in the context of your specific vehicle, past scans, and known patterns to give you a clear picture of your car's health. Get severity ratings, likely causes, and recommended next steps. ASK LEWIS ANYTHING Got a weird noise? Dashboard light you've never seen? Just ask. Lewis is a conversational AI mechanic who knows your car — its make, model, mileage, and full scan history. Ask follow-up questions, get maintenance advice, or figure out if that repair quote from the shop is fair. LIVE ENGINE DATA Monitor real-time data from your engine while you drive: RPM, coolant temperature, throttle position, boost pressure, engine load, and more. Extended data available for select vehicles including oil temperature, oil pressure, transmission temp, and torque. TRACK YOUR CAR'S HEALTH OVER TIME Every scan is saved automatically. Review your history, track recurring issues, and catch problems before they become expensive. Lewis analyzes trends across all your scans to spot patterns a single visit to the mechanic would miss. WORKS WITH YOUR CAR Lewis works with any 1996 or newer vehicle (OBD-II compliant) and connects via any standard Bluetooth OBD2 adapter. Extended diagnostics available for Alfa Romeo, BMW, Audi, and Mercedes with more makes coming soon.
