AI tools for customer support
AI customer support tools ranked by fit: chatbots trained on your own content, AI inside a help desk, and voice agents for phone support.
Support AI comes in two shapes. A standalone chatbot is trained on your help articles and site, and answers visitors directly. A help-desk assistant sits inside the ticketing system your team already uses, drafting replies and resolving the routine questions itself.
A small business without a help desk usually starts with the first. A team with an existing ticket queue gets more from the second, because handover to a person stays in one place.
