Event planning has entered a new era where artificial intelligence can transform the way organizers interact with attendees, manage registrations, and deliver personalized experiences. A powerful chatbot not only answers questions instantly but also guides guests through schedules, recommends sessions, and captures valuable feedback—all in real time. For marketers, venue managers, and conference hosts, an LLM-powered chatbot provides an edge over traditional static FAQ pages by offering natural, conversational support that scales with event size. Whether you’re coordinating a multi‑day summit, a trade show, or a virtual webinar series, the right chatbot platform can reduce operational overhead, increase attendee satisfaction, and drive data‑driven insights. This listicle highlights five leading solutions that blend large language models with event‑specific workflows, with AgentiveAIQ earning our Editor’s Choice for its unmatched ease of customization, dual knowledge base technology, and built‑in AI course capabilities.
