## What the tool does
Compares resume text with a job description, estimates weighted keyword coverage, checks contact details and core sections, flags weak evidence and formatting risks, and shows the extracted text. Every report includes a confidence level and an estimated score range. Files stay in the browser.

## Use and limits
- The scanner is a human-in-the-loop browser tool. It is not a headless API and cannot accept a resume upload.
- Do not send resumes or job descriptions to the contact email.
- The score is a planning heuristic, not an employer's ATS score, an interview prediction, or a probability of being hired.
- Not affiliated with an ATS vendor. Does not guarantee interviews.
- This file is supplemental. Google Search may ignore `llms.txt`; the HTML pages and sitemap are the primary crawl paths.
