On the other hand, I go and check Slack every now and then, clear out all my unreads, and then go back to work. If part of that process is typing '4' into one of those windows then it's basically zero-friction from my perspective.
In other words, as long as getting a Slack message doesn't already interrupt, distract, and annoy people, neither will this, and if it does then you can tune your Slack notification settings to handle that. Turn off push notifications for the bot and you'll only see/answer the question when you go into the app to clear out unreads.
These interactions typically take between five and fifteen seconds to complete, and then you're back to whatever you were doing before. We have tuned when and how Ava reaches out to minimize annoyance, and to keep productivity high. We also let employees respond at their own convenience, so it's not like you have to immediately give Ava your attention.

consider spelling it out like that on your front page. you've a two line description of what you do in the above that is 10x more informative and useful than what's currently there.
That should be the front page. It's informative.
I do think a transparent pricing structure is important though. I generally assume that 'call us' means 'if you have to ask you can't afford it', and immediately skip over any service that doesn't let me immediately calculate a specific number I'll pay every month, and I assume that 'schedule a demo' is like 'schedule a webinar', and that you're targeting your business (and pricing structure) towards C-level execs or upper management rather than the people who are actually implementing policies.
