Under the hood

Built for real techs.

Every feature is designed around how mechanics actually work — fast, hands-dirty, between jobs.

🔎

OEM Technical Data

Powered by MOTOR Information Systems — the same OEM data used by dealerships. TSBs, wiring diagrams, service procedures, labor times.

🤖

AI Diagnostic Engine

Claude AI trained on repair data synthesizes the most likely causes, ranked by real-world fix probability. Not generic code definitions — actual diagnostic intelligence.

📈

NHTSA Recall Check

Every query automatically checks for active recalls and common complaints. If there's a known campaign, you'll know before you start digging.
