ScriptGenie AI is a full-stack web application that automates this process by converting a single user-supplied topic into a complete, structured video script. The system integrates a vanilla HTML/CSS/JavaScript front end with a Node.js and Express.js back end, which communicates with the Groq inference API so as to query the open-weight LLaMA 3 language model through a structured, JSON-constrained prompt. The present paper details the system architecture, the rationale for selecting an inference-API-based design over local model hosting, the request-response workflow, and the prompt-engineering strategy used to obtain reliably structured output.
