An ATS keyword checker compares your resume text against a job description to find the critical keywords you are missing. Up to 75% of resumes are rejected by Applicant Tracking Systems before a human ever sees them — usually because of missing keywords. All analysis runs locally in your browser. Your data is never sent to any server.

How to Use the ATS Keyword Checker
Most large companies use Applicant Tracking Systems to automatically filter resumes before a human recruiter reviews them. The primary filter is keyword matching — if your resume does not contain terms from the job description, it may be rejected automatically. This free ATS keyword checker shows exactly which keywords you are missing so you can optimize your resume for each application.
Step 1: Paste the Job Description
Copy and paste the complete job description — the more complete, the better the analysis. Include the full posting: role summary, responsibilities, requirements, and preferred qualifications. Every section may contain keywords the ATS scans for.
Step 2: Paste Your Resume Text
Copy and paste your resume as plain text. If you have a PDF or Word document, paste the text content directly. Do not worry about formatting — just the words matter for keyword analysis. Export your resume as plain text from Word or Google Docs if needed.
Step 3: Review Your Match Score
Aim for a 70-85% keyword match. Below 50% means significant keywords are missing. Above 90% may indicate over-optimization that looks unnatural. Check the "High-Priority Missing Keywords" list and add the most important terms to your experience descriptions and skills section.
Step 4: Add Keywords Naturally
Never keyword-stuff your resume. Instead, integrate missing keywords naturally into your work experience bullets. "Led cross-functional collaboration to deliver project" reads better than an arbitrary list of buzzwords. Add a dedicated Skills section for technical terms and tools you genuinely know.
FAQ
Is my resume data private?
Yes, completely private. All analysis runs 100% locally in your browser using JavaScript. Your resume text and job description are never sent to any server, stored in any database, or shared with anyone. Your data stays entirely on your device.
What is an ATS and why does it matter?
ATS stands for Applicant Tracking System — software that companies use to screen resumes before a human recruiter sees them. ATS tools parse your resume for keywords from the job description. Resumes missing key terms are often rejected automatically. Optimizing for ATS means including the right keywords in the right context.
What match percentage should I aim for?
Aim for 70-85% keyword match. Below 50% and your resume is likely to be filtered out. Above 90% can look keyword-stuffed, which triggers spam filters in some ATS platforms. Natural inclusion of keywords in context, not mechanical repetition, is the best approach.
Should I copy keywords exactly from the job description?
Use the same terminology the job description uses. If the JD says 'cross-functional collaboration,' use that phrase rather than 'working with multiple teams.' ATS tools often do exact or near-exact matching, especially for specific skills, certifications, and tool names.
Is this ATS keyword checker free?
Yes, completely free with no signup, no account, and no limits. Analyze as many job descriptions and resume versions as you like at no cost.
Does ATS scanning look at formatting?
Yes. Many ATS systems struggle with tables, text boxes, headers/footers, images, and multi-column layouts. Use a clean single-column format with standard fonts. The content of your resume matters most, but poor formatting can prevent keywords from being parsed correctly.
