AI Chatbots

Introduction

AI chatbots cover support, sales, internal help, and consumer companion bots. The prompt is half the product.

Beginner analogy: Like designing a virtual employee — role, knowledge, tone, escalation.

Understanding the topic

Core concepts to understand:

• Persona + role + knowledge cutoff.
• RAG for product-specific knowledge.
• Tools for actions (refund, lookup).
• Escalation triggers to humans.
• Logs for QA & training.

Syntax reference

Visual workflow / architecture:

User message → intent classify → RAG → respond | tool | escalate

Real-world use

Intercom Fin, Ada, Drift AI, Zendesk AI — all this pattern with brand-specific persona.

Best practices

• Persona doc as system prompt.
• RAG for facts; never invent product details.
• Escalation built in.
