How it works
Most resumes never reach a human reviewer. Applicant Tracking Systems (ATS) screen incoming applications by parsing the resume text, extracting keywords, and ranking each application against the job description. A typical Fortune 500 company uses one. A typical job posting receives 200+ applications. The ATS does the first cut.
This tool simulates that first cut. It identifies the top keywords from the job description (with technical terms surfaced separately and boosted), then checks how many appear in your resume. The score gives you a quick read on alignment; the missing-keyword list tells you exactly which gaps to close.
The keyword analysis is heuristic — real production ATS systems are more sophisticated, with synonym handling and weighted scoring — but the keyword overlap signal is consistently the largest single driver of ATS ranking. Optimizing for it is the highest-leverage 30 minutes you can spend before submitting.
Frequently Asked Questions
What is an ATS?
An Applicant Tracking System (ATS) is software employers use to filter and screen resumes. Most companies — including over 95% of Fortune 500 firms — use one. ATS systems rank resumes against the job description by keyword match, formatting parseability, and completeness.
How does this ATS checker work?
It tokenizes both your resume and the job description, identifies the top keywords in the JD (frequency-weighted, with technical terms boosted), and checks how many appear in your resume. The score is the percentage of JD keywords matched. The tool runs entirely in your browser using JavaScript — nothing is uploaded.
What ATS match score should I aim for?
Aim for 70% or higher. 70-100% means strong alignment. 50-69% means there are real gaps you should close. Below 50% suggests the role may not be a match, or your resume needs significant tailoring.
Should I add every missing keyword to my resume?
No. Only add keywords that genuinely match your experience. Keyword stuffing is detectable and hurts you with human readers. If a missing keyword reflects experience you actually have, work it into a relevant bullet.
Is my resume data private?
Yes. The entire tool runs in your browser. Your resume and the job description never leave your device — they're not uploaded, not stored, not logged. You can verify by checking the network tab.
