What is the difference between an HR chatbot and an AI HR assistant?

An HR chatbot answers questions; an AI HR assistant also produces work. A chatbot replies to employees about leave, benefits or policies, from fixed answers or your handbook. An assistant can do that and also draft documents, summarise feedback, build onboarding plans and prepare reviews. An AI agent goes a step further and takes actions across tools on its own, which saves more time but needs closer checking.
