Frequently Asked Questions
How long does it take to set up an AI chatbot for my website?
With tools like Chatbase, you can have a working chatbot in under 30 minutes — upload your documents or paste your website URL, and it trains automatically. More complex chatbots with custom conversation flows (built in Voiceflow or Botpress) take days to weeks depending on complexity.
What percentage of customer questions can an AI chatbot actually answer?
Well-configured chatbots trained on comprehensive help content typically resolve 50-70% of inquiries automatically. Intercom's Fin claims up to 50% resolution out of the box. Tidio's Lyro resolves 70% of common questions. The percentage improves as you add more content and refine responses.
Do I need to code to build an AI chatbot?
No. Chatbase, Tidio, and Intercom Fin require zero coding. You upload your content, configure basic settings, and paste an embed code on your site. For custom conversation flows with branching logic and API integrations, Voiceflow uses a visual drag-and-drop builder — still no coding required.
