An AI chatbot can answer routine questions and route visitors, but it also creates accuracy, privacy, accessibility and support risks. A useful bot needs a defined knowledge source and a clear path to a human.

Deploy it without embarrassing yourself

- Always offer a human path
- Test unsafe and ambiguous prompts before launch
- Redact sensitive data, set retention and review a sample of answers weekly
Chat widgets are not free
They add scripts and network work. Measure page speed before and after activation and keep the widget from blocking first render.

Common questions
Can a chatbot replace support staff?
It can handle defined routine tasks. Complex, sensitive or disputed issues need accountable people.
Should a bot collect personal data?
Collect only what is necessary, explain the purpose, protect access and apply deletion rules.
Will chat slow WordPress down?
It can. Load it carefully, test real pages and avoid blocking initial rendering.
