Common Questions

FAQ

Yes. Fully free. No account, no credit card, no hidden charges. Enter your symptoms and get your diagnosis instantly.
CarMed uses GPT-4o, one of the most capable AI models available. It provides a strong starting point based on your symptoms and vehicle data. It's not a replacement for a professional mechanic inspection, but it gives you informed, data-backed guidance — the same level of initial triage a knowledgeable friend in the industry would provide.
No. VIN entry is optional but recommended. When you enter a VIN, CarMed pulls your exact vehicle specs from the NHTSA database — year, make, model, engine type — which helps the AI tailor the diagnosis to your specific vehicle.
Just describe it in your own words. The more detail you provide — when the noise occurs, under what driving conditions, any warning lights — the more accurate the diagnosis. CarMed understands natural language, so don't worry about using technical terms.
For anything flagged as High or Critical urgency — yes, absolutely. CarMed helps you understand what might be wrong and what questions to ask, but a physical inspection by a certified mechanic is always the right call for confirmed repairs. Think of CarMed as your pre-shop research tool.
Yes. CarMed doesn't require an account or any personal information. VIN lookups and symptom descriptions are processed to generate your diagnosis and stored anonymously for improving the service. We don't sell or share individual data.
