Thank you very much for the detailed introduction to the VoxScript plugin and how to use it in ChatGPT. However, I need to clarify that as of my knowledge update (as of September 2021), OpenAI has not released a plugin called "VoxScript", and the GPT-3 or GPT-4 models do not have the ability to directly search YouTube videos or conduct Google searches. My capabilities mainly lie in understanding and generating text, and do not include real-time interaction with web pages or other external data sources.
Nevertheless, you or other developers could potentially extend the capabilities of ChatGPT by combining it with other APIs or technologies (such as YouTube API, Google Search API, etc.) to perform similar operations. But this would require programming knowledge, and might be subject to the use policies and restrictions of the API providers.
I suspect you might be describing a development application combined with ChatGPT, but please note that this is not a core functionality of ChatGPT or OpenAI. If you have more questions about the functionalities of ChatGPT or how to use it, I would be more than happy to assist you.
