What it does
Retell AI is an AI tool for answering phone calls, building chatbots for your website and building AI agents. It charges by usage.
Retell AI is a platform for building and operating AI voice agents that handle phone calls. Teams use it for inbound reception, appointment setting, lead qualification, customer support, surveys, and outbound campaigns. It is aimed at contact centers, support and sales teams, and developers who need control over call flows and integrations. The product combines a visual drag-and-drop builder with testing, deployment, and call analytics. Agents can follow multi-step workflows, use functions and integrations, transfer calls to people, navigate phone menus, and read or write CRM data. Retell offers voice, chat, and SMS channels, and connects to existing phone systems through SIP trunking. A web dashboard and API with SDKs support both no-code setup and programmatic control. New users get $10 in free credits with full platform access. Pay-as-you-go voice agents start at $0.07 per minute, with cost depending on the models, voices, and add-ons selected; chat is billed per message. Enterprise plans add options such as single sign-on, custom data agreements, dedicated infrastructure, and implementation support.
