The AI Auto Repair Database — every vehicle, every code, one answer.
A repair manual tells you the procedure. A forum tells you what worked for someone else's car. MECH AI reasons over a structured database of OEM references, TSBs, OBD2 trouble codes, wiring diagrams, and documented fixes covering the mainstream US fleet — then gives you the answer for your exact vehicle, year, and symptom.

What is an AI repair database?
Type a code like P0420, describe a noise, or snap a photo of a part. The AI Mechanic pulls from a structured database of diagnostic trees and live OEM references, ranks the most likely causes by probability, and tells you the parts and tools you'll actually need — in plain English. No flipping through 900-page PDFs. No wading through ten years of conflicting forum threads.
Not forum scraping. Structured OEM reasoning.
OBD2 / DTC trouble codes
Every common diagnostic trouble code explained for your exact year, make, and model — with causes ranked by probability and real US repair-cost ranges.
TSBs & recalls
Live NHTSA Technical Service Bulletins, recalls, and owner-complaint data, matched to your specific vehicle generation.
OEM wiring diagrams
Manufacturer wiring and component diagrams, searchable in plain English instead of a dealer-portal maze.
OEM parts & tools
The actual parts and tools a repair needs, with fair-price guidance — not a generic shopping list.
Ranked diagnostic trees
Likely causes ordered by probability so you check the cheap, common things before condemning expensive parts.
Photo & symptom input
Type a code, describe a noise, or snap a photo of a part. The AI Mechanic reasons over all of it for your car.
