FAQ
1. Can you integrate HeyGen LiveAvatar into my existing Next.js or React app?
Yes. I can integrate the HeyGen LiveAvatar API or SDK into your existing application while preserving your current UI, authentication, and workflows wherever possible.
2. Will the avatar respond to users in real time?
Yes. I can configure the supported real-time interaction flow so users can speak with the avatar and receive AI-powered responses, depending on your HeyGen setup and selected AI services.
3. Can you connect OpenAI GPT or another AI model to my avatar?
Yes. I can help connect a compatible AI model to your voice assistant, enabling conversational responses and, where required, knowledge-base or API integrations.
4. Do I need an existing website or application?
No. I can help with a new Next.js or React implementation, or integrate the avatar into an existing application. Please contact me first to confirm the scope and requirements.
5. Will the integration work on mobile devices?
I can configure and test the integration for responsive desktop and mobile experiences. Actual performance depends on browser compatibility, network quality, device capabilities, and the selected HeyGen service.
6. What do you need from me to get started?
Please share your project requirements, current app or repository details, preferred AI model, and desired avatar interaction. Any required HeyGen credentials should be provided securely, never posted publicly. I'll review the scope before confirming the delivery timeline and price.
