Features

A mechanic who always asks one thing at a time

CarFixGPT doesn't dump every question on you at once — make, model, year, then the symptom, one step at a time, just like a real mechanic would.

Photo and voice diagnosis

Snap a photo of the warning light or the worn part, or record the strange noise — the AI factors both into its answer.

OBD-II code interpretation

Enter the code you read out (e.g. "P0301") and get what it means, what causes it, and what order to check things in.

Automatic vehicle recognition

Enter your VIN — or, in Germany, your HSN/TSN code — and the make, model, year, and engine fill in automatically.

Instructional video, one tap away

When a repair step is easier to follow visually, CarFixGPT suggests a relevant YouTube video to go with it.

Step-by-step repair guides

A real tool list, torque specs, and what to watch out for — not generalities, but steps you can actually follow.

Safety first

For brakes, steering, airbags, or high-voltage EV systems, it always points you clearly toward a professional shop.

How it works

Three steps to a diagnosis

Describe the symptom

A strange noise, a warning light, or a car that won't start — start simple, with text, voice, or a photo.

Answer a few questions

CarFixGPT asks about the essentials one at a time — no long forms, just the details that matter.

Get your next steps

A concrete diagnosis, a tool list, and a video if it helps — before you decide whether to fix it yourself or head to a shop.

You'll never have to repeat your car's details

Save your vehicle's details once — or auto-fill them from your VIN or HSN/TSN — and every new conversation will already know them.
