ATS Keyword Matching

We extract the significant terms from any job description and check them against your resume verbatim — the same way applicant tracking systems do.

Resume Visibility Improvement

Understand exactly which keywords are missing, which are present, and how your keyword density compares to what the role demands — before you apply.

Browser-Based & Private

All analysis runs entirely in your browser. Your resume and job description are never sent to any server, stored, or logged. Zero data exposure.

How it works

Three steps. Zero fluff.

01

Paste Job Description

Copy the full job posting — including responsibilities, requirements, and qualifications. The more complete, the more accurate the keyword extraction.

02

Paste Your Resume

Paste the plain-text version of your resume. Copy directly from your document or export as plain text from Word or Google Docs for best results.

03

Get Keyword Match Insights

The tool returns your ATS match score, every matched and missing keyword, a frequency table, recruiter visibility insights, and targeted suggestions.

Why it matters

Why ATS Keywords Matter

Most companies use Applicant Tracking Systems to manage hiring volume. Before a recruiter reads a single line of your resume, the ATS has already filtered it — based almost entirely on keyword presence.

Resumes that don't meet the keyword threshold are automatically deprioritised or removed from the candidate pool. The recruiter never sees them. This happens even when the candidate is qualified — the wording simply doesn't match.

Exact terminology matters. If the job description says "stakeholder management" and your resume says "client communication", most ATS systems will not count it as a match. Tailoring your resume per role — using the job description's own language — is the highest-leverage action available to job seekers.

Recruiters use ATS software

The majority of companies with structured hiring processes use an ATS to collect, sort, and rank applicants before human review begins.

Resumes are filtered automatically

ATS systems apply keyword thresholds. Applications below the threshold are ranked lower or excluded entirely — before any recruiter interaction.

Keyword alignment improves visibility

Candidates whose resumes reflect the job description's terminology consistently rank higher in ATS results and reach the recruiter review stage more often.

Exact wording matters

ATS parsing is literal. Synonyms, abbreviations, and paraphrases often fail to match. Using the job description's exact terms is the safest strategy.

FAQ

Common questions

What is an ATS keyword checker?

An ATS keyword checker compares your resume against a job description to identify which keywords — skills, tools, job titles, certifications — are present or missing. ATS systems filter candidates by keyword coverage before a human ever reads the resume.

How accurate is ATS keyword matching?

Our matching engine uses the same deterministic approach real ATS systems use: exact string comparison after normalization. It removes stopwords, lowercases all text, and extracts the top 50 significant terms from the job description. No AI inference — just direct comparison.

Does this tool store my resume?

No. All processing happens entirely in your browser using JavaScript. Your resume text and job description are never transmitted to any server. Nothing is stored, logged, or retained after you close the tab.

Can I use PDF or Word resumes directly?

The tool works with plain text input. To get the most accurate results, paste the text content of your resume directly. You can export plain text from Word, Google Docs, or copy directly from a PDF viewer.

How can I improve my ATS match score?

Add missing keywords naturally into your resume — in your summary, skills section, and experience bullets. Use exact terminology from the job description rather than synonyms. Spell out acronyms. Place the most important terms in your summary or headline.
