Check engine light on? Strange noise? Ask MECH AI, your AI mechanic, in your own words and get likely causes, next steps and repair guidance for your exact vehicle. No scanner needed. Have an OBD2 adapter? Read your trouble codes in plain English. A car diagnostics app with an AI mechanic, an OBD2 scanner and code reader, car repair guides, service bulletins and parts search, for DIYers and pros. AI MECHANIC Ask any car question in your own words ("check engine light is on", "grinding noise when I brake") and get answers built around your year, make, model and mileage. Add a photo of a warning light, part or leak. Works in English, Spanish, Portuguese, Russian, German, French and Italian. GUIDED DIAGNOSTICS Describe a symptom and get ranked likely causes, how urgent each one is and a DIY difficulty rating. Sessions ask quick, cheap checks first and resume where you left off.
