About Retell AI
What is Retell AI?
Retell AI is an LLM-based, voice-first conversational AI platform designed to automate phone calls with natural, human-like interactions. Unlike traditional IVR or basic voice assistants, Retell AI handles complex, multi-turn conversations, edge cases, and unexpected inputs — making it suitable for both inbound and outbound use cases.
Who is it for?
Retell AI is for businesses that need to automate phone-based workflows such as receptionist duties, appointment setting, lead qualification, customer service, debt collection, and surveys. It's ideal for call centers, healthcare providers, SaaS companies, and any organization looking to scale phone operations without adding headcount. It is not a fit for simple touch-tone routing or one-turn scripted interactions.
