# Customer Support Agents

> AI agents that resolve customer conversations across chat, email, and phone.

Customer support agents resolve conversations across chat, email, and voice — answering from your knowledge base and connected systems, then either resolving the issue or escalating it cleanly to a human. The metric that matters is resolution rate on your own tickets, not a vendor benchmark: a demo that handles tidy questions tells you little about how it performs on the ambiguous, angry, or multi-part messages real customers actually send. Evaluate how deeply it integrates with your help center, CRM, and back-end systems to take real action — issue a refund, check an order, update a record — rather than just deflecting with links, and how much control you have over tone, brand voice, and guardrails. Hand-off quality is critical: a good agent knows when it's out of depth and transfers with full context instead of trapping the customer in a loop. Look at how it's kept current as your product and policies change, and how it handles the languages and channels you support. These are usually enterprise products priced per resolution or per seat, so model the economics against your real ticket mix before committing. The honest promise isn't replacing your team; it's deflecting the repetitive volume so your humans spend their time on the cases that genuinely need a person.

## Frequently asked
**What is an AI customer support agent?**
It's an AI that autonomously handles customer inquiries — answering from your knowledge base and systems, then resolving or escalating — across chat, email, and voice.

**How do I evaluate a support agent?**
Measure resolution rate on your own tickets, integration with your help center and back-end systems, tone/brand control, and how smoothly it hands off to humans.

**Will it replace human support?**
It typically deflects routine, repetitive questions and frees humans for complex or sensitive cases, rather than replacing the team outright.
