AI Job Description Skill Matrix

A tiny developer-facing tool that takes a job description (JD), runs it through an LLM-powered extractor (with a deterministic fallback), and returns a structured skill matrix + summary you can copy the json as needed.

1- Works with or without an OpenAI API key
2- Strongly typed with Zod + TypeScript
3- Clean UI built with Next.js App Router + Tailwind
4- Fallback parser (regex + keyword maps) so you always get a result
