Hi, I will build the web app connecting HeyGen's Streaming Avatar API with Inworld's conversational AI — handling the WebSocket bridge between both services so voice input flows to Inworld and the response drives the avatar in real time. One key detail: I will route Inworld's text output through HeyGen's avatar speak endpoint rather than using separate TTS, keeping latency low and lip-sync accurate within a single pipeline. Questions: 1) Do you already have API keys for both HeyGen and Inworld? 2) Does your LearnWorlds plan support custom JavaScript inside iframes? Looking forward to your response. Best regards, Kamran

Hi I can build this MVP as a simple web app that connects HeyGen Live Avatars with Inworld AI so students can speak in real time with an AI avatar inside your courses. The main challenge here is not the UI, but making the voice loop feel smooth and reliable across mic access, streaming responses, avatar rendering, and iframe embedding inside LearnWorlds, so I would solve that with a lightweight frontend architecture and careful handling of real-time events. My approach would be to integrate HeyGen for the avatar layer, connect Inworld for conversational speech-to-speech, and wrap both into a clean embeddable web experience that works inside LearnWorlds with minimal friction. I have experience with JavaScript, API integrations, real-time communication flows, and AI-driven interactive interfaces where latency and usability matter more than overengineering. The deliverable would be a working MVP, simple enough to understand and extend later, plus a clear walkthrough of setup, keys, and embedding steps. I can also help make the structure scalable so future improvements do not require a rebuild. And I can help you so on by delivering a practical first version that is functional, clean, and easy to reuse. Thanks, Hercules
