Simple, honest pricing

A shop visit just to get a problem diagnosed usually runs $120 or more — before any actual repair. Diago doesn't hide anything, and costs a fraction of that.

Why isn't this completely free?

Every diagnosis runs on real AI models that cost money each time. The subscription covers heavy users and keeps the service fast for everyone else.

What if the diagnosis is wrong?

AI output may be incomplete or incorrect for your specific vehicle. Diago provides general information only and is not a substitute for inspection by a licensed mechanic — especially for anything safety-related.

Can I cancel my subscription?

Yes, anytime. Cancelling stops future billing immediately.

Is my payment information safe?

All payments are processed securely by Stripe. Diago never sees or stores your card number.
