How to Build an AI Chatbot for Customer Support (Step by Step)
A practical guide to scoping, building, and launching website chatbots that resolve support issues accurately.
Define the top 20 questions first
Support chatbots fail when teams try to automate everything on day one. Start with high-volume, low-risk intents — order status, billing FAQs, account setup — and measure deflection before expanding scope.
Connect to your real knowledge sources
Ground responses in help center articles, internal macros, and product docs via retrieval. The bot should cite sources and escalate when confidence is low.
Design escalation paths humans trust
Users tolerate AI support when escalation to a human takes one click and passes full context. Integrate with Zendesk or Intercom, attach the transcript, and tell users what happens next.
Launch with evals, not hope
Build a test set of real tickets and run it before go-live. Track resolution rate, escalation rate, and CSAT weekly for the first month.
