reeteesha-roy/yt-description-generator — reverse-engineered prompt

Build me a simple web app where I can paste a YouTube video topic or rough idea and get back a catchy title plus a strong video description using OpenAI. I want it to feel useful for creators, so please make the results sound engaging and SEO friendly, not robotic.

The page should be clean and easy to use, with a text box for the video idea, a button to generate, and separate areas for the title and description. Please add real time character counts with clear color warnings so I can stay within normal YouTube limits. I also want an easy copy button for each result, plus a small section with helpful optimization tips or best practices for YouTube.

Use a simple Python backend with a basic HTML and CSS front end, and read the API key from an env file so I can run it locally. If anything is unclear, check the current OpenAI docs online and make sensible choices.
