FAQ

Repair database questions.

Is the MECH AI repair database free?
Yes — it is free to start. The free tier includes a daily AI Mechanic chat allowance — no card required — plus unlimited access to the public diagnostic code library. Paid plans (from $7.99/mo) add higher daily allowances and pro features; Premium includes up to 300 AI Mechanic messages per day.
Does it cover my car?
Start with your year, make, model and diagnostic code or symptom. Available repair information varies by vehicle and source. Check that a reference applies to your vehicle before using it; an AI answer is guidance for further checks, not a confirmed diagnosis.
How is this different from ALLDATA or Mitchell ProDemand?
MECH AI brings vehicle context, AI-assisted diagnostic guidance and repair-information tools into one account. Try it alongside the reference tools you already use and compare coverage for your actual jobs. OEM parts and wiring lookups require Shop Repair; coverage varies by vehicle and source.
Is this just ChatGPT for cars?
MECH AI combines an automotive workflow with saved vehicle context, code lookup and repair tools. Enter the vehicle details and symptoms so the guidance has useful context. Check source coverage and plan access when you need OEM information.
