Start Talking to Your Car
Learn how to have real conversations with your vehicle using Car AI's natural language interface
How do I start talking to my car?
After connecting your OBD-II dongle, open Car AI and simply start asking questions! Try "How is my engine running?" or "Why is my check engine light on?" The AI understands natural language and responds in plain English, just like talking to a knowledgeable friend about your car.
Which cars are compatible with Car AI?
Car AI works with most cars manufactured after 1996 that have an OBD-II port. This includes virtually all gasoline cars from 1996+ and diesel cars from 1997+. Check our compatible cars list for specific models and brands.
What kinds of questions can I ask my car?
Ask anything! "Why does my car vibrate?" "Is it safe to drive?" "How's my fuel economy?" "When do I need an oil change?" Car AI understands context and provides personalized answers based on your vehicle's real-time data and maintenance history.
My dongle won't connect to the app
Make sure your car engine is running and the dongle is firmly inserted into the OBD-II port. Check that Bluetooth is enabled on your phone and that you're within range. Try restarting the app and re-pairing the dongle through the settings menu.
The app shows "No Data Available"
This typically means your car's engine isn't running or the OBD-II system hasn't initialized. Start your engine and wait 30-60 seconds for all systems to become active. Some cars require driving a short distance to activate all sensors.
Error codes won't clear after repair
Some error codes require multiple drive cycles to clear automatically, even after the underlying issue is fixed. If codes persist after confirmed repairs, consult a professional mechanic as there may be additional related issues.
