Zeno Chatbot

Zeno Chatbot is a free, actively developed WordPress chatbot plugin built to give any site a smart AI assistant that answers from your own content. It uses your WordPress pages and posts as its primary knowledge base and extends this with a dedicated WooCommerce product index, sitemap indexing, and the ability to upload PDFs and images from your media library as additional knowledge sources. Setup requires no coding — install the plugin, enter your OpenAI or Gemini API key, select your content sources, rebuild the index, and the chatbot is live. Responses are rendered in rich markdown with headers, lists, code blocks, and clickable links for a polished user experience.

A notable addition in recent versions is the dedicated WooCommerce product indexing workflow, which lets you select which product fields to include during indexing and processes the catalogue in chunks with a progress indicator. Additional features include a Knowledge Notes data source for injecting supplementary context directly into the chatbot’s knowledge base, sitemap-based indexing, conversation auto-close and auto-summary controls, an analytics dashboard covering total conversations, response times, and satisfaction ratings over 14 days, and chat-to-email integration for converting live conversations into trackable email threads. The widget is fully customisable with control over colours, position, agent name, and avatar.

Zeno Chatbot is completely free to use, with premium features currently in development. Your only cost is the API usage billed directly by OpenAI or Google based on your conversation volume.
