Overview
Retell AI is a voice AI platform for automating phone calls with AI agents. The site positions it as a way to build, test, deploy, and monitor production-ready voice agents that can sound human, handle multi-turn conversations, and execute tasks during live calls.
The platform is built for organizations that want call automation without giving up control over behavior, integrations, or deployment workflow. Its core tooling includes a configurable agent framework, simulation testing, call analytics, knowledge base support, telephony features, and options for both pay-as-you-go and enterprise use.
Key capabilities
Testing and monitoring tools
Use simulation testing, call analytics, transcripts, continuous QA, and performance dashboards to evaluate behavior before and after launch.
Real-time function calling
Add built-in or custom functions to call flows so agents can book appointments, process payments, update records, and transfer calls in real time.
Telephony controls
Connect to your existing phone numbers and telephony stack through SIP trunking, plus branded call ID, batch calling, and verified phone numbers.
Knowledge and retrieval
Use a knowledge base with auto-sync support and streaming retrieval to keep call responses aligned with current website content and other source material.
Integrations and workflow connectivity
Extend workflows with integrations across CRM, automation, scheduling, customer service, and other business systems.
Common use cases
Reception and call routing
Deploy an AI receptionist to answer incoming calls, route callers, and handle routine front-desk interactions with less manual intervention.
Appointment setting
Set up agents that schedule meetings or appointments and use real-time function calls to update calendars or booking systems.
Structured outbound and inbound calls
Use the platform for lead qualification, customer service, debt collection, or survey calls where the agent needs to follow a structured conversation and respond to unexpected input.
Outbound campaigns and telephony workflows
Support operations teams that need batch calling, branded caller ID, verified numbers, and telephony integrations for outbound campaigns.
Post-launch optimization
Monitor and improve deployed agents with call transcripts, analytics, simulation testing, and continuous QA to find failure patterns and refine call performance.
