Stella AI Chatbot for Websites and Customer Support
Stella AI Chatbot helps businesses automate customer support, capture more leads, and boost website engagement with smart AI-powered conversations. The Free edition includes a powerful FAQ-first chatbot with fuzzy matching, category-based navigation, custom welcome and no-match messages, lead capture, and session-level chat logs. You can easily customize widget appearance, upload avatars, generate embed code, and control allowed domains for secure usage.
For teams that need advanced automation, Stella AI Chatbot Pro adds AI-powered conversations and Vector Retrieval (RAG) to answer user questions from indexed website content. Pro supports multiple AI providers, model testing, crawl controls, RAG ranking options, human handoff after unmatched queries, and advanced analytics for matched/unmatched trends. It also includes stronger production controls such as admin CSRF protection, HTTPS enforcement options, retention settings, and scalable PostgreSQL/pgvector support.
Whether you run a startup site, service business, SaaS platform, or documentation portal, Stella AI Chatbot helps you combine FAQ reliability with modern AI intelligence in one unified system. Start with Free for instant value, and upgrade to Pro when you’re ready for smarter answers, deeper automation, and enterprise-ready control.
