Very classic one is x.ai or Amy or whatever they call it now. They overhyped their capability of building a smart assistant for reading and replying to emails and ended up being an average service that sort of works.
Earlier, they kept telling me that I have jumped their queue and will soon get access. Now they ask me to upgrade the plan to keep using it. Complete BS!
Average? I've used it at least a dozen times in the last month, and it's worked perfectly every time. It may not be the fastest, but it's certainly the best... YMMV, of course.
It's good but considering auto-reply feature of Gmail and integration with other apps like Calendar and Hangouts, I wouldn't pay for any such solution.
Of course, assuming the organization use Gsuite else, maybe x.ai fits the bill.
