← Back to Diago AI

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.

Every new user gets 3 free diagnoses — no card required. Diago is an informational AI tool; results are estimates only. Have a qualified mechanic verify safety-related issues before driving or attempting repairs.

Unlimited

$9.99 /month

Pay per use

$4.99 one-time

Two diagnoses a month already pays for itself with Unlimited — great for weekend mechanics, gearheads, and anyone who works on cars, trucks, motorcycles, or powersports as a hobby (or a side hustle).

Why isn't this completely free?

Every diagnosis calls real AI models (Claude for text, GPT-4o for photo analysis, Gemini for video) which cost money to run. Charging a small amount keeps the service fast and reliable instead of disappearing in six months.

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 brakes, steering, suspension, and other safety-critical systems. See our Terms of Service for full disclaimers.

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.
