AI assistance means that the adapter can work with the smart voice assistants you have on your mobile phone. The most well-known include "Siri" for Apple devices and "Google Assistant" for Android phones. The adapter itself doesn't have any artificial intelligence in it, but acts as a connector. It usually has a dedicated button on it, which when pressed activates the assistant on the paired phone. You can then use the microphone in the adapter to enter voice commands, for example, to start a call, dictate a text message, start navigation or control music. You can do all these things without having to hold the phone in your hand.
