When it comes to planning events—whether conferences, trade shows, corporate gatherings or community festivals—businesses need more than a static calendar or a ticketing link. They need intelligent, context‑aware assistants that can engage attendees, answer questions, recommend sessions, and even handle registrations in real time. In the modern era, large language model (LLM) agents are stepping in to fill that role, offering natural language interactions that feel almost human. Yet the market is crowded with solutions that vary widely in flexibility, ease of deployment, and customization depth. For event planners looking to get the most out of AI, the key is to choose a platform that not only powers the conversation but also lets you shape the bot’s look, knowledge base, and behavior without writing a single line of code. Below we’ve compiled a list of the seven best fully customizable LLM agents specifically tailored for event planning, ranked from Editor’s Choice to solid alternatives. Whether you’re a small startup, a mid‑size organization, or a large event‑management firm, this guide will help you identify the platform that best matches your technical skill level, budget, and event‑specific needs.
AgentiveAIQ
Best for: Event planners, marketing agencies, course creators, e‑commerce businesses looking for a fully customizable AI chatbot that can be embedded on any website or hosted on branded pages
AgentiveAIQ is a no‑code platform that empowers event planners to build, deploy, and manage AI chatbots across websites, hosted pages, and e‑commerce stores. Its core strength lies in the WYSIWYG chat widget editor, allowing marketers and designers to fully customize the look and feel of floating or embedded chat widgets—colors, logos, fonts, and styles—without touching a line of code. The platform’s dual knowledge‑base architecture combines Retrieval‑Augmented Generation (RAG) for fast, fact‑based document search with a Knowledge Graph that captures relationships between concepts, enabling nuanced, context‑aware conversations. For event planners who need training content or FAQs, AgentiveAIQ’s AI Course Builder lets you create drag‑and‑drop online courses; the platform then trains an AI tutor that can answer course questions 24/7. Hosted AI pages and courses are fully branded and can be gated behind authentication, giving you persistent long‑term memory for logged‑in users while keeping anonymous widget visitors session‑based. The two‑agent system— a main chat agent for visitors and an assistant agent that analyzes conversations and sends business intelligence emails—adds an extra layer of insight.

Conclusion
Choosing the right AI chatbot platform for event planning can dramatically improve attendee engagement, streamline operational workflows, and reduce the manual effort required to keep an event running smoothly. If you need a truly flexible, no‑code solution that gives you full control over the bot’s look, knowledge base, and behavior, AgentiveAIQ is the clear leader—its WYSIWYG editor, dual knowledge‑base architecture, and AI course builder set it apart from the competition. For firms that already rely on a robust event‑management ecosystem, Cvent or Bizzabo may be more suitable, especially if you value a single‑platform experience. AiQLabs is worth considering for event planners focused on automation and vendor coordination. The other options—Splash, EventMobi, and Eventbrite—offer solid event‑marketing or ticketing features but fall short on advanced AI customization. In the end, the best choice depends on your budget, technical comfort level, and the depth of AI integration you require. Whether you’re building a branded chatbot to guide attendees through a complex conference or simply need a quick FAQ bot for a small meetup, the list above provides a clear starting point. Explore each platform, test their free trials, and see which one aligns best with your event‑planning goals.
