A developer built Invoxy.xyz, a free tool that parses PDF resumes and generates personalized interview questions. Unlike generic AI prompts, it uses context from your specific work history and a target job description to create targeted feedback, addressing a key gap in standard LLM interview prep.

The tool runs client-side with pdf-parse for privacy, injecting resume details into a system prompt for a Google API-powered LLM. It adopts a skeptical 'Red Team' persona to probe vague claims and employment gaps, simulating tough interviewer scrutiny rather than offering generic encouragement.

Built with a Next.js frontend and PDF.js for extraction, Invoxy is currently a free beta. The project highlights a growing trend: developers tailoring AI tools for specific, high-stakes professional tasks where generic models fall short, moving beyond one-size-fits-all chatbot interactions.
