What it does

Sierra is a platform for building and running conversational customer service agents. Teams give it standard operating procedures, transcripts, recordings or plain English descriptions, and the Ghostwriter tool turns them into a multilingual agent with guardrails that runs on chat, SMS, WhatsApp, email, voice and ChatGPT. Insights tooling monitors conversations, flags ones that need attention and supports A/B experiments, and every change can be reviewed before it ships. Sierra describes outcome-based pricing but does not publish rates.
