Show HN: Intervu – Free, BYOK Interview Prep (Groq/Gemini/OpenAI)

Hey HN, I’ve been interviewing recently and got frustrated with two things: Copy-pasting context (resume, job description) into LLMs repeatedly. "AI Interview" tools that charge monthly subs just to wrap an API call. So I built Intervu, a free dashboard to organize your prep. The main difference: It’s Bring Your Own Key (BYOK). You use your own OpenAI, Gemini, or Groq keys and pay the provider directly. I don't charge anything. Features: Panic Mode: High-yield prep for when you're short on time. System Design Bank: Dedicated section for architecture questions. Company Recon: Auto-fetches company news and stats. Resume Tailoring: Detailed feedback based on specific job URLs. It’s open source and keys are stored locally in your browser. GitHub: https://github.com/vvknyn/interview-os https://github.com/vvknyn/interview-os Demo: https://www.intervu.cc https://www.intervu.cc
