Google Assistant is much more than a voice search app.
You can interact with the app and it helps you make your day more productive.
Ask Google assistant to “Find emails from a co-worker.” Or, find pictures of my dogs.
You can also ask it questions like “What are the best prices of flights from Charlotte to Las Vegas”
The Google assistant provides a two-way dialog and she prompts with the next step question. It is literally trying to be your assistant and it does a good job.
