Conversation-aware multimodal interface
Agents shift between voice, text, and visuals based on what the customer needs, while preserving the conversation so the customer does not have to restart or repeat information.
Sierra
Freemium
Sierra is an AI agent platform for customer conversations across voice, messaging, email, and other channels. Its multimodal agents combine spoken, written, and visual interactions in one conversation, choosing the medium that best fits the customer’s task.
What is Sierra?
Sierra is an AI agent platform for customer conversations across voice, chat, email, WhatsApp, and other channels. Its multimodal agents combine voice, text, visuals, and interactive components in one conversation, allowing the interface to change as the customer’s needs change.
The core purpose is to match the communication mode to the task: voice can capture an explanation, text can preserve details, and visuals can make options easier to compare or select. Customers can move between these modes without starting over or repeating themselves. Sierra supports experiences such as displaying alternate flights with departure times, layovers, and prices, or presenting a seat map for direct selection.
Teams build an agent once and deploy it across supported surfaces. With Sierra’s MCP UI integration, teams can design and host product cards, comparison tables, calendars, forms, and other interactive components, controlling their appearance, content, and behavior across deployments.
What can Sierra do?
Interactive visual components
Teams can place product cards, comparison tables, calendars, forms, images, and videos directly in conversations to support browsing, comparison, troubleshooting, and selection.
Build once, deploy across channels
A single Sierra agent can power experiences across voice, chat, email, WhatsApp, and other supported surfaces rather than requiring separate agents for each channel.
Full-screen expansion for complex tasks
Interactive experiences can expand when they need more space, supporting calendars, long comparison tables, and multi-step forms.
Voice interactions with real-time adaptation
Sierra’s voice channel is designed to handle interruptions, background noise, and accents, and can detect customer sentiment to adapt tone and pace.
Channel-specific customer-service workflows
The platform supports inbound and outbound voice, messaging, email automation, live-assist suggestions, and publishing an agent to ChatGPT with controlled journeys, data, and capabilities.
Use Cases
“Travel disruption and rebooking”
An airline agent can present alternate flights with departure times, layovers, and prices in the conversation, then continue after the customer selects an option.
“Seat selection”
A customer can discuss a booking by voice and use an interactive seat map to choose a seat without leaving the conversation.
“Product comparison and purchase support”
A retail or consumer brand can use spoken questions alongside product cards, comparison tables, images, or videos to help customers evaluate options.
“Guided forms and account service”
Customer-service teams can use interactive forms for structured, multi-step tasks while retaining conversational context.
“Email and agent-assisted support”
Support organizations can automate email responses using account context or give representatives ready-to-send, grounded suggestions and access to the same actions used by the AI agent.
