How to choose

  1. 1

    Where do your customers reach you: website chat, email, WhatsApp, Instagram?

  2. 2

    How is the AI billed? Per seat, per conversation or per resolution changes the cost a lot.

  3. 3

    What does it learn from, and how do you stop it from inventing answers?

  4. 4

    How does the hand-off to a human work when it cannot answer?
