The average shop diagnostic fee is $100–$150 — Pro pays for itself the first time Carlos saves you one.
Common questions
Can I cancel anytime?
Yes — cancel in your account portal and you keep access until the end of your billing period.
What counts as a diagnosis?
Each time you hit Ask Carlos and get a result. Follow-up questions in the same session don't count.
Do I need an account to use Free?
No. Free diagnoses work without signing in. Create an account to save history and sync across devices.
