We were given the task of "make a bot". This was when bots were first becoming a thing and one of the VP's decided we needed one. No idea what for, just we need one. We were unenthusiatic to say the least to be given this task with no problem that's it's solving so we set out to find one. And actually, we did. And customers couldn't get it quick enough.
And as this started as just a way to help users answer policy questions, we eventually want to turn it into more of a genral contextual help system. This way if the user is in the middle of booking a flight and they pull up the Assistant, they'll get relevant question right off the bat pertaining to booking airfare. Also, we have hopes of someday personalizing the Assistant so it knows specifically what your personal policy is and not just a generic company policy. We found that for many companies the policy may change from person to person or role to role.
