Retell AI

Retell AI lets developers create human-sounding conversational Voice AI in a matter of hours with a response time of about 800ms, so conversations feel more natural. The platform also lets users create, test, deploy and monitor production-ready AI voice agents in a more streamlined way.

Retell AI comes with a range of features to customize the conversational experience. Users can create workflows in minutes and then deploy them through a variety of channels, including phone calls, web calls and mobile apps. The platform also offers post-call analysis, sentiment analysis, task completion status and latency analysis for more insight.

The platform's proprietary Turn-Taking model, end-of-turn detection and interruptibility features all work together to create a more lifelike interaction with the voice AI. It supports multiple languages, including voices and voice cloning, to keep the conversation engaging and natural sounding.

Retell AI is designed to be scalable and secure, with a focus on reliable voice services and the ability to handle large volumes of calls without a hitch. Users can set up predefined templates and function calls easily. The company says it's HIPAA compliant, with SOC Type I & II certifications in the works.

Pricing is on a pay-as-you-go basis, with varying rates depending on the voice engine API and LLM agent you use. For example, the Conversation Voice Engine API costs $0.08 per minute with OpenAI/Deepgram voices or $0.10 per minute with Elevenlabs voices. LLM agents cost $0.02 to $0.20 per minute, depending on the model you use. There's also an Enterprise Plan for companies with high volumes or custom requirements, with discounted pricing and premium support.

Retell AI is designed to give customers a natural and accessible voice AI experience that's also affordable.
