The platform acts as a digital teammate for your support staff by surfacing relevant knowledge base articles and past ticket resolutions instantly.

Sierra

Sierra is a conversational AI platform that helps you transform customer service from simple chat into autonomous problem-solving. Instead of basic bots that just answer questions, you can build AI agents that actually perform tasks—like upgrading a subscription, tracking a complex shipping route, or managing a return—by connecting directly to your existing enterprise systems and data.

You can ensure your AI agent stays on brand and follows your specific business logic through a robust reasoning engine. The platform focuses on high-quality, human-like interactions that reduce the need for manual intervention while improving customer satisfaction. It is designed for consumer-facing brands that need to scale their support operations without sacrificing the nuance and personality of their brand identity.
