Retell AI

Retell AI is an AI voice agent platform that lets businesses build, test, and deploy smart phone agents. These agents can handle both incoming and outgoing calls with human-like conversation skills and response times of under one second.

Unlike traditional phone systems that use robotic voices and menu options, Retell AI creates natural conversations. The agents can understand what callers are saying, respond appropriately, and even handle interruptions just like real people would.

The platform integrates with existing phone systems, customer databases, and business tools. It supports over 18 languages and meets important security standards like HIPAA and GDPR. Businesses can use these voice agents for customer support, sales calls, appointment scheduling, lead qualification, and many other phone-based tasks without needing large call center teams.
