MECH AI: Diagnostic & Repair

Car diagnostic AI for every driver and mechanic. MECH AI is the automotive multitool — AI mechanic chat, OBD2 scanner, car repair guides, wiring diagrams, and parts finder in one app. Scan OBD2 fault codes, decode your check engine light, get plain-English car repair help, and find the right parts. Built for DIY car owners and professional mechanics who'd rather get the right answer the first time.

One app. Every job.

ASK ANYTHING. GET THE ANSWER THAT ACTUALLY APPLIES TO YOUR CAR.
Our AI Mechanic knows your make, model, year, and trim. It pulls from manufacturer service bulletins, real OEM repair procedures, and a language model tuned for cars — not a forum thread from 2014.
