What are Retell AI and VideoSDK?
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.
VideoSDK is a real-time communication platform that provides APIs and software tools for developers to build video and voice applications. Instead of creating video calling systems from scratch, developers can use VideoSDK's ready-made tools to add features like video meetings, live streaming, screen sharing, and AI-powered voice agents to their apps.
The platform works across all devices and operating systems, including web browsers, mobile apps, and desktop applications. It uses advanced technology to ensure smooth video quality even with poor internet connections and provides global infrastructure with 150ms worldwide latency.
VideoSDK offers both free and paid plans, starting with 10,000 free minutes every month. This makes it perfect for startups, small businesses, and large companies that need reliable video communication features without building everything from scratch.
