If you can’t answer a question, “I don’t know” is a much better response than generic marketing fluff.
I took the first screen shot a few years ago. The improvement in the current version is obvious:
Now the answers match, to a reasonable extent, the question I asked.
And if the system really doesn’t understand the query (like: “What is the unit of power?”), it has the grace to admit it. “I’m sorry, I didn’t understand your last question” is an honest approach, and it’s OK to follow that with some marketing copy.
It’s also interesting to note that the picture of the human in the original has been replaced with a more clearly artificial, cartoon-like figure, and that the ambiguous title “Online Assistant” has been replaced with “Virtual Assistant”.
