How it works

Three steps from warning light to answer.

  1. 1

    Plug in an adapter

    Any Bluetooth OBD-II adapter fits the port under your dash. Most cars built since 1996 have one.

  2. 2

    Connect in the app

    ChatOBD pairs with the adapter and reads your car's trouble codes and live sensors in seconds.

  3. 3

    Ask anything

    Get a plain-language read on what a light means, how urgent it is, and what to check first.

One connection. More understanding.

FAQ

Good questions.

Do I need extra hardware?

No. ChatOBD works without an adapter. A Bluetooth OBD-II adapter adds direct vehicle telemetry and improves automatic trip detection accuracy, so it is recommended for the complete experience.

Which cars are supported?

Any car with an OBD-II port. That covers nearly all gasoline cars sold in the US since 1996, and most cars sold in Europe since the early 2000s.
