About Retell AI

Retell AI is a platform for building and operating voice agents for telephone workflows. Teams can create an agent, update its behavior, test it and monitor calls after deployment. The published platform also includes chat agents, call transcripts, analytics and simulation testing. Its quality-assurance tools examine production conversations for audio, language and operational issues, helping operators investigate failures. This makes Retell infrastructure for an organization's call workflows rather than an independent guarantee of correct answers. Pricing is usage-based, with voice and chat billed differently and introductory credits available. Final cost depends on the chosen configuration and usage, so a single starting rate does not describe every deployment.
