The short answer

Start with MECH AI if you want to ask follow-up questions about symptoms, codes or test results. Consider Carly if a specific supported scan, service function or coding option is your priority. Both can help you interpret evidence; neither a fault code nor an AI answer confirms which part needs replacing.

When Carly is better

A genuine advantage, not a disclaimer in fine print.

You have checked that Carly supports the specific customization you want.
You want vehicle scans and available service functions in the same scanner app.
You prefer consulting an available Smart Mechanic document for a stored fault code.

When MECH AI is better

You want to discuss what a test result changes about the next suggested check.
You use different scanners and want to bring their codes into one conversation.

What the spec sheet does not tell you

1. Compare the full package and billing period

Carly’s published pricing guide lists Basic at $89.80 once, Premium from $68.89/year and All Brands at $109.88/year, with a scanner included. These are guide examples, not a verified checkout quote. Check the linked configurator for your brand, region, included features and renewal price. MECH AI’s Free tier lets you try Quick Help within daily limits; paid plans add allowances and tools. Compare the same period and the functions you actually need.

2. Carly does offer repair guidance

Smart Mechanic includes fault explanations, component checks, schematics and repair tips for some codes. Carly’s support page says it is billed annually and appears when a saved fault has an available document. Check its inclusion in your chosen package. MECH AI offers a conversation you can continue as you collect evidence; suggestions still need verification against the vehicle and appropriate repair information.

3. Coding support is not the same as brand support

Carly’s coding support article points BMW and MINI owners to its feature list and asks VW, Audi, SEAT and Skoda owners to check their exact vehicle in the app. It explicitly says Mercedes coding is not offered. A supported brand does not guarantee every control unit or customization. MECH AI does not change control-module coding.

4. Use the tools for the job you have

You can bring a code from Carly or another scanner to MECH AI without connecting that scanner to MECH AI. Direct MECH AI scans use the iOS or Android app and a compatible BLE or Wi-Fi ELM327 adapter; web chat does not scan the vehicle. Check vehicle, adapter and plan support before purchasing for a specific scan function.

Common questions

Does Carly always require a separate scanner purchase plus a subscription?

No. Carly’s current pricing guide describes a one-time Basic package and annual Premium packages that include the scanner. Confirm the actual offer, included features and renewal terms in its pricing configurator.

Does Carly provide repair instructions?

Yes. Smart Mechanic offers repair information for some saved fault codes with available documents. Its support page describes annual billing and manufacturer-specific diagnostic access requirements; confirm your package before buying.

Can MECH AI code my car?

No. MECH AI does not offer control-module coding. It can help you understand a symptom or code and organize suggested checks. Use a compatible coding tool for supported setting changes.

Can I try MECH AI without buying a scanner?

Yes. Start free with a symptom, photo or copied code in Quick Help. Free-plan daily limits apply. Direct vehicle scanning is separate and requires a compatible adapter and the mobile app.

Start with the diagnosis

Describe the symptom or paste the code. MECH AI will help you decide what to test before you buy a part—or another tool.
