AI chatbot vs rule-based bot
Rule-based bots follow fixed paths. AI chatbots handle open conversation, but need guardrails.

Model usage cost per conversation
Choose rule-based bot if
- You have a few simple, repeated questions
- You need strictly scripted answers
Choose ai chatbot if
- Visitors ask varied questions before buying
- You want leads qualified through conversation
Our take: Use rules for simple FAQs. Use AI when conversation quality affects whether a lead converts, and add rules around it.
Questions, answered
Can we combine both?
Yes. A common design is rules for sensitive parts, such as pricing, and AI for the open conversation.
