There is a version of the AI chatbot pitch that promises to replace your support team. It is not true, and believing it is how companies end up with an expensive system their customers route around.
Answering questions that have a documented answer. If the information exists in your FAQ, your help centre, your product docs or your past ticket history, a well-built bot will find it and phrase it clearly, at three in the morning, in the customer's own words rather than yours.
It is also good at triage: working out what a message is about, how urgent it is, and who should see it — which quietly removes a great deal of work before any human is involved.
Anything requiring authority. Refunds, exceptions, apologies that need to mean something, and decisions that cost money should route to a person. So should anything the bot is not confident about — a bot that says "let me get someone" is far better than one that guesses.
Make the handoff to a human obvious and always available
Train it on your actual past conversations, not a generic corpus
Review what it got wrong every week for the first month
Tell customers they are talking to a bot
Done that way, the bot absorbs the repetitive half of your support load and your team gets to spend their time on the half that actually needs them.
