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 evidence—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. Vehicle data and OBD2 functions vary by adapter and vehicle. Start your next diagnosis with MechNostic.

Have been using it on every job for the past couple of weeks now and can’t get over how easy it makes the job. ### 5/5 — Brilliant app *2026-02-03* Genuinely impressed with this. The layout is clean, it’s really quick to use, and the accuracy is better than I expected. What stands out most is that it explains why it’s suggesting things instead of just listing faults, which makes a big difference and actually helps you understand what’s going on. It already feels like a solid, reliable tool to have on hand when diagnosing issues. ## Frequently asked questions about MechNostic ### What is MechNostic?
