Retell AI for Web

Platform summary

Retell AI is a browser-accessible platform built to help engineers craft conversational voice agents that sound natural. It supports the full lifecycle — from design and testing to deployment and ongoing observation — and is aimed at teams building voice-driven experiences at scale.

Core capabilities

• Stateful multi-prompt agents and simpler single-prompt agents to suit different workflow complexities.
• Integration with external language models, allowing you to plug in the LLM of your choice.

Conversation management and analytics

Retell AI includes an advanced turn-taking system that improves conversational flow by handling interruptions and speaker overlaps gracefully. After calls, you can run automated analyses to extract operational metrics:

• Sentiment analysis to surface emotional tone and user satisfaction.
• Post-call breakdowns that highlight key moments and performance indicators.
• Task-completion tracking so you can see whether agents finished assigned objectives.

Deployment, monitoring, and scale

The platform is designed for production use: deploy voice agents to live environments, monitor their behavior in real time, and iterate based on measurable insights. Built-in monitoring and reporting features help maintain quality as usage grows.

Language and use-case flexibility

Retell AI supports multiple languages and is adaptable to a variety of verticals, from customer support to interactive voice assistants. Its feature set is intended to handle diverse conversational scenarios and complex interaction flows.
