MechNostic is an AI-powered vehicle diagnostic assistant built for professional mechanics and automotive technicians. A fault code is a starting point, not a diagnosis. MechNostic helps you combine symptoms, DTCs, vehicle information and test results to work out the next useful check. **AI-GUIDED FAULT DIAGNOSIS** - Enter fault codes or describe what the vehicle is doing - Add photos of scan-tool screens, warning lights or VIN plates - Get practical diagnostic checks, with explanations of what each test can confirm - Share new readings and results to refine the next step - Revisit previous diagnostic conversations **NOSTIC CONNECT: OBD2 DIAGNOSTICS** Use a compatible Bluetooth or Wi-Fi OBD2 adapter to access supported vehicle data. Depending on the vehicle and adapter, you can: - Read and interpret diagnostic trouble codes - View live sensor readings - Check vehicle information - Bring scan results into a conversation with Nostic Agent **BUILT FOR THE WORKSHOP** From an intermittent fault to a second opinion on a repair direction, MechNostic is designed to help skilled technicians work through the evidenceβ€”not guess at parts. **GET MORE WITH PRO** Unlock additional AI diagnostic capabilities and features through an optional subscription. Available features depend on your plan. MechNostic supports professional judgement; it does not replace manufacturer procedures, hands-on testing or safe working practices.
