Show HN: Refine.tools – 10 free AI career tools, no signup, no data stored

Hey HN. I built a suite of 10 free AI career tools. Resume builder, cover letter generator, salary negotiation scripts, voice-powered interview coach, job description analyzer, and a few more.

The whole thing runs in your browser. No accounts, no data storage, API calls go to OpenAI but nothing persists. Built with Next.js on Vercel.

It started as a personal tool to help me job hunt, and I kept adding stuff. Figured others might find it useful.

I'd love feedback on the tools themselves and what else would be useful to add.
