How is the match score calculated?

The tool extracts the most important keywords from the job description, checks how many appear in your resume, and combines that keyword overlap with a check for standard resume sections into a single 0–100 score.

What is an ATS and why does keyword matching matter?

An Applicant Tracking System is software that screens resumes before a human sees them, often ranking them by how well they match the job description. Mirroring the role’s key terms (truthfully) helps your resume surface.

Does it upload my resume?

No. Both your resume and the job description are analysed entirely in your browser, so nothing you paste is sent to a server.

Should I just stuff in every keyword?

No. Add only terms that genuinely reflect your experience, worked in naturally. Keyword stuffing reads poorly to humans and modern ATS systems weight context, not just raw counts.

How is the score worked out?

It extracts the top keywords from the job description, measures how many appear in your resume for the bulk of the score, and adds points for having standard sections such as experience, education, skills, and contact details.

Does matching keywords guarantee an interview?

No. Keyword match helps you pass automated screening and shows relevance, but recruiters still judge substance. Use the missing-keyword list to add terms you genuinely have experience with.

Is my resume kept private?

Yes. Both your resume and the job description are processed entirely in your browser, so nothing is sent to a server.

How to use ATS Resume Score Checker

The ATS resume score checker measures how well your resume matches a specific job by comparing the two directly in your browser. It pulls the most important keywords from the job description, checks how many appear in your resume, verifies that standard sections are present, and combines those into a 0–100 readiness score. You also get a list of matched and missing keywords so you can tailor your resume — no upload, no AI, and nothing leaves your device.

Paste your resume text into the first box.
Paste the target job description into the second box.
Press Check match to see your score.
Add relevant missing keywords to your resume and re-check.

Your data never leaves your device — 100% private processing.

How applicant tracking systems read resumes

Most mid-size and large employers use an Applicant Tracking System to collect and filter applications. These systems parse your resume into fields, scan for the skills and terms in the job description, and often rank or score candidates before a recruiter ever looks. Resumes that use the same language as the posting — the exact tools, skills, and role terms — tend to rank higher and are less likely to be filtered out. That is why tailoring each application to mirror the job’s key terms, honestly, is one of the highest-leverage things a job seeker can do.

What the checker looks at
Signal	Why it matters
Keyword overlap	Relevance to the specific role
Missing keywords	Gaps to address before applying
Section coverage	Parseability and completeness

Tailoring without keyword stuffing

The goal is to mirror the job description truthfully, not to cram in every term. Modern ATS software weighs context and frequency, and recruiters immediately spot a wall of buzzwords. Work the relevant missing keywords into real bullet points that describe what you actually did — "Built a React design system used by 40 engineers" rather than a bare list of technologies. Keep your standard sections clearly labelled so the parser can find them, quantify achievements where you can, and re-run the checker to confirm the important terms now register. A resume that reads well to a human and matches the posting is the one that wins.
