Do I need an OBD-II scanner to use AutoClarity?

No. The guided questions work from what you describe and can see. Some tests later in a diagnosis ask for a basic tool such as a digital multimeter, and the app explains exactly what to do or how to pause and come back.

Is there a free demo?

Yes. The demo walks through a simulated starting problem, clearly labelled as a simulation, with no account or payment required.

Can AutoClarity tell me exactly what is wrong with my car?

It narrows down possible causes from the evidence you provide and tells you plainly whether a cause is suspected, supported or still unconfirmed. It does not replace a physical inspection, and it will say when a test is still needed.

Can AutoClarity review a repair estimate?

Yes. The AI Repair Advocate explains what each line of a repair estimate covers, how the charges break down, and what questions are worth asking before you approve the work. A basic explanation is free, an AI review is $24.99, and a written professional second opinion from a GG Motorworks mechanic is $79.99.

Comparing estimates

How to compare mechanic quotes without guessing

Two shops, two prices, and no way to tell whether the cheaper one is a bargain or the expensive one is thorough. Comparing quotes properly comes down to a handful of specific things.

Compare like with like

Parts quality: original equipment, premium aftermarket, or economy. A cheaper quote often uses a different grade of part.
Labor hours: compare quoted hours, not just the total. Flat-rate hours for the same job should be close.
Scope: one quote may include an alignment, a fluid change or a diagnostic fee that the other leaves out.
Warranty: parts and labor coverage, and how long it lasts.

Different diagnoses are the real signal

If the two shops recommend completely different repairs for the same symptom, the price comparison is meaningless until you know which diagnosis rests on evidence. Ask each shop what test produced their conclusion.

A shop that can explain the measurement, the live data or the fault code behind the recommendation is easier to trust than one that names a part without a test.

Watch the charges that hide in plain sight

A diagnostic fee charged separately before any work is quoted.
Shop supplies and environmental fees as a percentage, rather than a stated amount.
A bundle of maintenance items added to a safety repair.
Parts markup that is not disclosed when you ask for a parts breakdown.

A five-question script that works

What test showed this part has failed?
Can you break the quote into parts and labor for each line?
Which items are safety-related and which can wait?
What grade of parts is this price based on?
If this does not fix it, what is the next step and what does it cost?

Where AutoClarity fits

You can put either quote through a review and get each line explained: what it covers, whether the wording is consistent with the diagnosis, and which questions to ask. The free summary explains the estimate in plain terms; a paid review goes deeper, and a professional second opinion puts a mechanic’s written assessment against it.

Common questions

Should I always choose the cheapest quote?

No. The cheapest quote can be the best value for a simple job and a bad deal for a complex one, depending on part quality, warranty and whether the diagnosis was tested.

Is a dealership always more expensive?

Not always, and not always for the same reason. Dealerships often use original equipment parts and manufacturer procedures, which can matter for some repairs and not for others.

What if one shop found a problem the other missed?

Ask what evidence supports the finding. Additional recommended work is not automatically unnecessary, but it should be explainable.
