What Are AI Customer Service Agents?
AI customer service agents are autonomous software systems that handle customer inquiries, resolve issues, and manage support tickets using large language models and natural language processing. Unlike traditional chatbots with scripted responses, these agents understand context, reason through problems, and take actions across your support systems.
According to MarketsandMarkets research, the global AI for customer service market will grow from $12.06 billion in 2024 to $47.82 billion by 2030—a 25.8% compound annual growth rate. The CB Insights 2025 report identifies 6 companies generating over $100 million in annual recurring revenue, including Gorgias, Sierra, and Kore.ai.
What AI Customer Service Agents Actually Do
The shift from rule-based chatbots to agentic AI represents a fundamental transformation. These agents can handle complex multi-turn conversations, remember context across sessions, and execute actions in your business systems—not just provide scripted responses.
