It’s easy to ask Google Assistant to forget the last thing you said to your Nest or Home smart speaker or display (“Hey Google, that wasn’t for you”), but now there’s a way to temporarily keep Google Assistant from remembering what you said in the first place.
Google’s newly launched Guest Mode acts like an incognito tab in Chrome. While Chrome’s incognito mode won’t remember your browsing history, Google Assistant’s Guest Mode lets you chat with the Assistant on your Google smart speaker without your interactions being recorded.
Just say “Hey Google, turn on Guest Mode” to activate the new privacy mode. When you do, you’ll hear a special tone on your Google smart speaker, while a banner will appear on a Google display.
