What can Sierra do?
Agent building with Ghostwriter
Upload SOPs, transcripts, photos, audio recordings, or describe a goal in plain English, and Ghostwriter builds a multilingual, multichannel agent with guardrails.
No-code agent management
Use Agent Studio to define journeys, instructions, tools, dynamic data, knowledge, and branding without writing code, with real-time traces to debug behavior.
System and data connectivity
Connect structured data from systems of record and data warehouses, and use integrations to let agents take actions or hand off conversations with full context.
Testing and observability
Test and refine agents with simulations, AI-powered evaluations, regression testing, voice simulations, monitors, and experiments.
Personalization and proactive workflows
Use an agent data platform with memory, customer data, recommendations, and proactive engagement to personalize interactions based on conversation history and real-world signals.
Use Cases
“Omnichannel customer support”
Deploy a customer-facing agent that can answer routine questions, maintain a consistent tone, and operate across the channels your customers already use.
“Task completion with business systems”
Connect an agent to order management, CRM, or other systems of record so it can process tasks such as returns, claims, or account-related requests from start to finish.
“No-code agent operations”
Let CX teams configure journeys, knowledge, and brand guidelines without code, while using traces and simulations to refine behavior before release.
“Personalized engagement”
Use conversation history, customer data, and recommendations to tailor responses and trigger proactive next-best-action workflows based on real-world signals.
“Validation and continuous improvement”
Test agent changes with regression testing, voice simulations, monitors, and experiments before rolling updates into production.
