# RESOPT — tailor your résumé to any job, with the AI you already have
RESOPT rewrites your **real** résumé (and a cover letter, if you want one) to match a specific
job description and pass **ATS** (applicant tracking system) screening — never inventing
experience. It also shows your **ATS match score** and the exact keywords you're missing.
It runs on **your own** Claude / ChatGPT / Perplexity — **no API key, nothing to pay.**
## Add it to your AI (one time)
Your connector URL:
> ### `https://resopt-mcp.onrender.com/mcp`
- **Claude** (Pro — web or Desktop): Settings → **Connectors** → **Add custom connector** → paste the URL.
- **Perplexity** (Pro/Max): Settings → **Connectors** → **Add custom connector** → paste the URL.
- **ChatGPT**: coming via the app directory.
## Use it
Paste your résumé and the job description into the chat, then say:
> *"Optimize my résumé for this job"* — and, if you'd like, *"write a cover letter."*
You'll get an ATS-safe `.docx` to download, plus your ATS match score.
## What you get
- Your real experience rewritten in the job's language — **never fabricated**
- **ATS match score** + the exact missing keywords
- **Cover letter** on request
- Clean, single-column, ATS-safe `.docx` (Workday, Taleo, Greenhouse, iCIMS, and more)
## Privacy
Stateless — your résumé and the job description are used only to run your request and are **not stored**.
> ⏱️ It's on a free host that sleeps when idle, so the *first* request after a quiet spell takes
> ~30–60s to wake up. After that it's quick.
