MECH AI vs FIXD
MECH AI vs FIXD — start with a scan or a repair question.
FIXD pairs its sensor with an app to read and clear engine codes. MECH AI lets you start with a symptom or a code you already have, then explore possible causes and useful next checks. You can ask on the web, iOS or Android without buying hardware. Direct mobile scanning needs a compatible adapter.

Which fits your task?
Choose FIXD for its sensor-and-app scanning workflow, including code clearing and optional Premium services. Choose MECH AI to work through a repair question with the vehicle details and evidence you provide. If you already own FIXD, you can bring its codes into Quick Help. Neither a code nor an AI answer alone confirms which part needs replacing.

When FIXD is the better pick
Consider FIXD if…
- You want to plug a sensor into the car and read or clear codes live yourself, repeatedly, without owning a separate scan tool.
- Emissions pre-check, issue forecasting, and vehicle-history reports are core to how you use the app — those are FIXD Premium features MECH AI doesn’t replicate 1:1.
- You specifically want a human mechanic hotline. MECH AI provides AI assistance; it does not provide a human mechanic hotline.
How to use MECH AI alongside your scan
1. Bring the code and symptoms
Enter the full code, including its first letter, and add the year, make, model and engine. Describe when the warning appeared and any other codes on the scan. You can also start with a symptom.
2. Plan a check before buying a part
Ask which test would distinguish the possible causes and what observations would change the next step. Confirm the diagnosis and applicable repair procedure. AI-generated diagrams are separate from manufacturer wiring information; OEM lookups require Shop Repair and coverage varies.
3. Choose a plan for the work you need
Start with the free daily AI allowance. Plus at $7.99/month adds higher allowances, up to 5 saved vehicles and repair guides. Compare Premium and Shop Repair when you need their additional tools. See plan limits and billing options.

Every comparison names where the other tool genuinely wins, not just where we do.
