Best AI Customer Service Agents: FAQ

How much does an AI customer service agent cost?

+

Most charge per resolution: Fin is $0.99, Gorgias about $0.90–$1.00, Zendesk $1.50–$2.00 and Salesforce Agentforce $2 per conversation. Freshdesk's Freddy sells sessions at $49 per 100.

Can I use an AI agent without switching helpdesks?

+

Yes. Fin works on top of helpdesks such as Salesforce and Zendesk, and Siena AI plugs into existing helpdesks. Zendesk, Freddy and Agentforce work best inside their own platforms.

What share of tickets can an AI agent resolve?

+

It depends on your ticket mix and how good your help content is. Repetitive questions like order status, returns and password resets automate well; billing disputes and edge cases still need people. Test on your own tickets before committing.

How long does it take to launch?

+

Self-serve tools like Fin, Gorgias and Tidio can go live in days by learning from your help center. Enterprise platforms like Decagon, Sierra and Ada are sales-led rollouts that usually take weeks.

Does the AI agent hand off to a human?

+

All the agents listed here escalate to human agents when they can't resolve an issue. Check that the handoff carries the conversation history so customers don't repeat themselves.
