Get a real answer — grounded in OEM procedures, your shop's history, and the kind of diagnostic logic that takes a decade to learn. WHAT YOU GET - Forgy — an AI co-pilot trained for automotive diagnostics. Ask it about any DTC, any vehicle, any symptom. Get a focused diagnostic path, not a wall of generic text. - MOTOR-licensed procedures, torque specs, and DTC flowcharts — straight from the source, viewed in-app, never bounced to a browser. - Live OBD2 streaming via Bluetooth — pair your existing scanner (OBDLink MX+, Autel, Launch, others) and stream PIDs, freeze frame data, and live sensor readings in real time. - VIN scanner with camera + barcode + AI fallback — get the right vehicle profile in seconds. - Multi-format scanner screenshot support — snap a photo of any scan tool's screen, paste it into Forgy chat, get an analysis. - Vehicle history that persists — every car your shop touches builds a record. Pull it up next time. BUILT FOR SHOPS, NOT CONSUMERS ForgePilot isn't an OBD2 toy or a parts-buying app. It's a professional diagnostic tool for working technicians at independent shops.
