Frequently Asked Questions

Is it okay to use multiple voice assistants at once?

It's possible, but switching between different assistants across devices means learning separate habits and commands for each, which can feel inconvenient β€” sticking to one main ecosystem tends to be more convenient.

Is a voice assistant always listening to what I say?

Generally, it only activates when it detects a set wake word, like "Hey Siri" β€” before that, it's designed not to transmit audio to the cloud.
