HOW IT WORKS

Pay only for what you actually do.

A quick text question is 10 credits. A full diagnosis with a photo, OBD code, and PDF report is about 150. Audio and video count by the 30-second clip — and that's the whole price list.

A "full diagnostic" here = text symptoms + photo + OBD lookup + PDF report ≈150 credits. Most car problems get solved in one. Audio and video clips cost more — full breakdown on the right.

Heavy week? Top up.

No volume games — just $1 = 100 credits. Top-ups stack on top of your monthly grant and never expire. Buy when you need them; ignore otherwise.

FAQ5 ENTRIES

Every AI action burns credits according to the table above. A short text question is 10cr; a full diagnostic with a photo, OBD code, and PDF report is around 150cr. Audio and video are billed per 30-second block and rounded up.

Monthly credits reset on each grant — what you don't use expires. Top-up credits never expire. Plus's grant fires on each subscription renewal; Free refreshes on a rolling 30-day window.

No — both clear at $0.01/credit. Plus exists for predictability: auto-renewing 2,000 credits/month so you never have to think about top-ups during a diagnosis.

Anytime from settings. You keep your remaining credits through the end of the billing period; no charge after that.

If a diagnosis fails on our side, we refund the credits automatically — they land in your top-up bucket so they don't expire with the next reset.

DO THE MATH

$150 for a scan. Once.
Or $19.90/mo, every month.

Plus runs the same diagnostic ~13 times a month — photos, audio, OBD lookups, PDF you can take to any shop. A year of second opinions for less than one inspection fee.
