# Sierra

Sierra is an enterprise-grade AI customer service platform that enables companies to build sophisticated conversational AI agents for customer support. Unlike simple chatbots, Sierra's agents are trained on company-specific knowledge, can take real actions (process returns, update accounts, book appointments), and handle complex multi-turn conversations with the nuance and empathy of a skilled human agent. Sierra powers customer support for leading brands and is designed to resolve issues end-to-end, dramatically reducing contact center volume while improving customer satisfaction.
