I just used it for 15 minutes and I like the direction Google is going with it. Once you turn Bard extensions on, you use the “@“ character to get a pop up list of services like GMail, Google Drive, and many others; choose one, then ask your question.

First steps, and I look forward to seeing future improvements. I wonder how they will monetize this? I was just using it with my free GMail account.

Both Microsoft, with Office 365, and Google have the customers and web properties that can make good use of new types of LLM applications.
