Understand your car before you go to the garage
Plug in a Bluetooth OBD2 adapter: DiagAuto AI reads the fault codes and the sensor data, then the AI explains each code to you in plain language. A noise, a vibration, but no code? Describe it to the AI: it answers you and suggests where to look.
- Fault codes explained
- Live sensor data
- AI chat, even without a code
How it works
Plug in and connect the adapter
Pair the OBD2 adapter just once in your phone's Bluetooth settings, then select it in the DiagAuto AI app.

Fault codes from the engine and the other control units, live sensor data, fuel consumption, history and PDF report.

The AI explains each code in simple language, helps you start from a symptom and answers your questions in a chat.
See what the AI does →No reprogramming, ever
The app reads the fault codes, the sensors and the vehicle information, and changes no setting. The only action possible is clearing the engine fault codes (a standard OBD2 function), only when you ask for it and confirm it.

Why DiagAuto AI?
For years, I diagnosed the cars of my family and friends. Every time it was the same thing: I read the fault codes with a scan app, then I had to leave it to search the Internet for what each code meant.
With the arrival of artificial intelligence, I started asking it my questions… still jumping from one app to another. And I noticed that its diagnoses were getting more and more relevant.
So I told myself: why not bring the two together? That is how DiagAuto AI was born: a single app that reads your vehicle's codes and explains them clearly, so that you understand your car before you go to the garage.
Frequently asked questions
Is my vehicle compatible?
Almost all cars have an OBD2 port from the late 1990s and early 2000s onward, depending on the regulations of each country.
Do I need a specific adapter?
No, a standard Bluetooth OBD2 adapter (ELM327 or compatible) is enough. See how to connect it
Does the app work on iPhone?
Not for now: DiagAuto AI is available on Android.
Can the app damage my vehicle?
No. It never reprograms the control units and changes no setting. The only action possible is clearing the engine fault codes (a standard OBD2 function), which you must explicitly confirm.
Can I try it without an adapter?
Yes, demo mode lets you discover the app with simulated data.
