Retell AI
Builds scalable AI voice agents for phone calls and customer interactions
Retell AI is a platform for building, testing, deploying, and monitoring AI voice agents designed for phone calls and customer interactions. It provides a voice AI API that enables natural conversations with 500ms latency and supports over 18 languages for global dialing. The agent builder allows custom creation of voice agents using intuitive tools and integrations with CRMs and telephony systems.
Testing features include built-in LLM simulations to handle edge cases and ensure agent performance. Deployment options cover phone calls, web calls, SMS, and chat interfaces. The monitoring dashboard tracks success rates, latency, user sentiment, and call history to identify issues quickly.
Retell AI maintains compliance with SOC 2 Type 1 and 2, HIPAA, and GDPR standards. It offers scalability for millions of concurrent calls with 99.99% uptime and fallback mechanisms for reliability. Integrations connect to any CRM, automation platform, or database.
Competitors include Vapi for developer-focused prototypes and Bland AI for outbound sales emphasis. Retell AI provides pay-as-you-go pricing with enterprise discounts, generally lower than bundled plans from rivals like Synthflow.
Users appreciate the human-like voice quality and ease of scaling, though some note a developer-oriented interface. For implementation, begin with the live demo, then use documentation to configure a basic agent and monitor initial deployments for optimization.
