What is an AI mechanic?

An AI mechanic is software that helps explain vehicle symptoms and trouble codes and suggests possible next checks. MECH AI uses the details you provide alongside a saved garage and dedicated repair tools. It does not inspect the vehicle or confirm a failed part. Check its suggestions against test results and applicable service information.

How it works

From a symptom to the next check.

1. Describe the problem

Type the symptom in plain English or drop in the trouble code — "P0420 on a 2014 Camry", "rough idle when cold", "grinding when I brake".

2. Work out what to check

Add your year, make, model, engine and symptoms. MECH AI suggests possible causes and checks to help you decide what evidence to gather next.

3. Go deeper if you need it

Use code lookup, repair guides and vehicle-reference tools as needed. Plan limits and coverage vary; confirm that a source or procedure applies to your vehicle.

Working with AI repair help

Bring the details. Check the answer.

Start with your vehicle

Keep your vehicle in your garage and check the selected vehicle before asking. Include the engine, mileage and observations that could change the answer.

Check the evidence

AI can make mistakes. Verify specifications, part fitment and procedures against applicable service information and test results before acting.

In your hand, at the car

Ask a question on web, iPhone or Android. Bring your symptoms and any codes or test results you already have.

FAQ

Quick answers.

Is it really free?

Yes. Create an account to use a daily AI Mechanic chat allowance — no card required. The public diagnostic code library does not require an account. Paid plans add tools and higher daily allowances; they do not remove all usage limits. Check current allowances and checkout terms on the pricing page and in the app.

How is this different from ChatGPT?

General assistants can work with the vehicle details you provide. MECH AI brings a saved garage, code lookup and dedicated repair tools into an automotive workflow. That workflow is the reason to try it; an AI answer alone does not establish a correct diagnosis or that one assistant is more accurate than another.

What vehicles does it cover?

You can ask questions about many makes and models, but reference data, diagrams and scanner functions vary by vehicle, market, model year and equipment. Add the engine and relevant details, verify the selected vehicle, and check coverage before relying on a specific feature.

Can I use it as a professional mechanic?

Yes, as a repair-assistance tool. Premium includes TSB lookup and AI wiring diagrams; Shop Repair adds OEM wiring and parts diagrams for covered vehicles. Allowances and coverage apply. Use the applicable manufacturer procedure and test results for the work. Shop Manager is a separate guided operations pilot.
