Overview

Sierra helps businesses build customer-facing AI agents that handle conversations across chat, SMS, WhatsApp, email, voice, and ChatGPT. It is aimed at teams that want to improve customer service and drive revenue with one agent across channels.

The product includes Ghostwriter for building production-ready, multilingual, multichannel agents from SOPs, transcripts, whiteboard photos, audio recordings, or plain English prompts. It also includes tools for optimizing agents with flagged issues and proactive insights, plus visibility into every change.

Sierra adds conversation analytics through Insights Explorer, Monitors, Experiments, and Observability. It also supports long-horizon planning, customer memory across systems and touchpoints, outcome optimization, and proactive workflows triggered by real-world signals.
