What is an AI agent?
An AI agent is software that uses a large language model to understand natural language, make decisions, and take actions across channels — answering questions, qualifying leads, or completing multi-step tasks — rather than just following a fixed script.
An AI agent goes beyond a scripted chatbot: it understands what a person means, grounds its answers in your data (via retrieval), decides what to do, and takes real actions — booking an appointment, updating a record, routing a request — across voice, chat, email, or SMS. Unlike a decision-tree bot, it handles the judgment steps a human used to. Reliable agents include guardrails and retrieval grounding to keep answers accurate and prevent hallucination, plus escalation paths to humans. Well-scoped agents commonly automate high-volume support, booking, and lead qualification 24/7, paying back within months of the labor they replace.

What is the difference between an AI agent and a chatbot?
A chatbot follows scripted rules; an AI agent understands language, grounds answers in your data, and takes actions across channels. The agent automates judgment work, not just Q&A.
How much does an AI agent cost to build?
Roughly $6,000 for a single-channel chat agent up to $40,000+ for an orchestrated multi-agent system, plus small ongoing model/usage costs.
