Sounds like a search engine with extra steps. Kudos to them for removing one of the extra steps, which would usually involve going to a search engine and then finding and vetting sources anyway... AI appears, to me, to be nothing but a rough draft generator that requires both input from a human and output with the draft it creates.

Email and message summarization also introduces new problems that don't happen when using a chatbot for questions and answers since through the process of summarization it removes information from the original text and may remove key information or mischaracterize the message. The ways it may do this stuff isn't exactly predictable either. It's also harder since it's not about proving that something is true or not based on outside sources, it's about it being accurate to what they said, which may not be provable to outside sources.
