What an ATS resume checker actually does

Applicant tracking systems score resumes primarily on how well the text of your resume overlaps with the language of a specific job description. This checker simulates that step. It extracts the most weighted keywords and short phrases from the job description, scans your resume for them, and reports a single match score along with the keywords you cover and the ones you are missing.

This is not a substitute for a human recruiter reading your resume — but it is a reliable stand-in for the first automated filter that most job applications go through. If your resume fails this check for a specific role, it usually also fails the real ATS filter for that role.

Why running the checker in your browser matters

Your resume contains personal and employment information you probably do not want sitting on a third-party server. This tool runs the entire analysis — PDF text extraction, tokenization, and scoring — inside your browser, so the resume text is never transmitted anywhere. You can verify this by opening your browser's network tab while the analysis runs.

Because there is no server to scale and no API key to protect, the checker is also free to use without a sign-up wall. The trade-off is that the analysis is keyword-based rather than LLM-based, but for most ATS use cases keyword coverage is the dominant signal anyway.

How to act on the match score

Treat the score as a coarse indicator rather than a precise grade. Below 40 usually means your resume and the job description are talking about very different things — either wrong role fit, or the resume needs targeted rewriting for this application. Between 40 and 70 is the range where most tailored edits pay off: add missing keywords where you have genuinely done that work, and adjust your summary line to mirror the job title.

Above 70 is considered a strong match. At that point the more impactful edits are quantifying your achievements (numbers, scale, impact) and making sure the top missing keywords appear in your most recent role rather than only in an older job. Recruiters and ATS systems both weight recent work more heavily than earlier history.

Does my resume get uploaded to a server?

No. All processing happens in your browser. The resume text and job description never leave your device.

What file types can I upload?

PDF files are supported for text extraction. Text-based PDFs work best — scanned or image-only PDFs have no extractable text. You can also paste resume text directly.

How accurate is the match score?

The score reflects weighted keyword coverage of the job description, which is the primary signal most ATS systems use. It is a reliable first-pass filter but does not replace human review.

Is there a limit on how many resumes I can check?

No. Because the analysis runs locally, there is no per-day quota. You can run as many checks as you want.

Why do I see some generic words in the missing keywords list?

Job descriptions contain some recurring phrases that carry weight even when they look generic. If a phrase appears multiple times in the JD and not in your resume, it is surfaced so you can decide whether to include it.
