Training an OpenAI Assistant for Website Integration: No-Code vs. Coding Approach

I want to integrate an OpenAI-powered assistant into my company’s website as a chatbot. The goal is for users to ask any questions about our company and receive precise, short, and informative responses.

I have the following queries:

  1. How can I train the assistant to provide accurate and to-the-point answers?
  2. Do I need coding skills to develop and integrate this chatbot, or is there a way to train it simply by providing documents and instructions?
  3. What are the best practices for ensuring the chatbot understands user queries effectively?
  4. Can this be done using a no-code platform, or do I need custom API development?
  5. How can I use HeyGen to provide responses in both chat and video formats? Is there a way to automate video generation based on user queries?

I would appreciate any guidance, best tools, or step-by-step approaches to achieving this efficiently.
