Google Assistant is a virtual voice assistant from Google that connects with your favorite apps and games, allowing you to control various aspects of your life such as home devices, streaming services, and even automating tasks like setting reminders or sending texts. You can access Google Assistant through the app on your Android or Apple device, car, or other compatible devices, without needing a smart speaker like Google Home. Additionally, Zapier integrations enable automation of workflows with popular apps like Trello and Slack, making it easier to manage work and home life efficiently.
