Decode warning lights, noises, and symptoms before you reach the shop.
AI-Powered Auto Education
Big M Mechanic AI Academy
Helping You Understand Your Vehicle—Powered by AI.
Ask the AI Mechanic
A guided diagnostic interview — it asks the questions a master technician would, then gives you ranked causes, cost, and a safety call.
Diagnostic session
Found on the driver-side dash, door jamb sticker, or your insurance card.
I'm the Big M AI Mechanic — think of me as an ASE Master Technician on call.
Tell me what your vehicle is doing (sounds, smells, warning lights, when it happens), and I'll ask a few targeted questions before giving you a ranked diagnosis, cost range, safety call, and next steps.
To start: what year, make, model, and engine is the vehicle, and what is it doing?
Educational only — not a replacement for a licensed technician
