Voice-native conversational AI agents for customer and employee touchpoints
A voice-native platform for building and orchestrating AI agents, with agent and model selection, rule-based actions, and human-assisted resolution.
Agents are designed to keep listening and understanding through interruptions, background noise, and the unpredictable flow of real conversations.
Layered guardrails at instruction, task, function, and channel level, a proprietary PII-detection LLM, tenant isolation, encryption, and full audit logging.
Deploy agents to digital channels and physical locations — phones, drive-thrus, in-car systems, kiosks, and employee tools — from a single system.

Automate work across thousands of apps — no code required
Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
Store structured data your workflows can read and update, keeping records in sync across tools.
