How to check your resume against a job description

Paste your resume and the job description, press Check my resume, then add the missing keywords you genuinely have and fix any flagged formatting issues. The whole check takes a few seconds and runs in your browser.

  1. Copy the plain text of your resume (from Word, Google Docs or a PDF) into the first box, or open a .txt file.
  2. Paste the full job description — requirements and responsibilities — into the second box.
  3. Review the missing keywords. They're sorted by how often the job description mentions them.
  4. Work the relevant ones into your summary, skills and experience bullets using the employer's wording.
  5. Fix any warnings in the resume checks, then run the check again.

How the match score works

The checker picks out meaningful words and short phrases from the job description (ignoring filler like "strong experience"), keeps technical terms such as C#, .NET, Node.js and CI/CD intact, and weights each one by how often it appears. Your score is the share of that weight found in your resume, with simple variants like manage, managed and managing counted as the same word. Real applicant tracking systems each work differently, so use the score to spot gaps rather than as a guarantee. Need to trim length afterwards? The word counter helps, and the diff checker shows exactly what changed between two versions of your resume.

Frequently Asked Questions

An ATS (applicant tracking system) is software employers use to collect, store, search and filter job applications. Recruiters often search or rank candidates inside it by keywords, job titles and skills, so a resume that uses the same terms as the job description is easier to find. How much filtering is automatic varies a lot between companies and products.
There is no universal standard — every ATS and every checker scores differently, so a number from one tool can't be compared with another. As rough guidance for this tool, 70% or more means your resume already covers most of the job description's key terms, 40–70% means there are clear gaps worth closing, and under 40% usually means the resume isn't tailored to that job yet. Aim to cover the requirements you genuinely meet rather than chasing 100%.
No. The analysis runs entirely in your browser with JavaScript — your resume and the job description never leave your device, and nothing is uploaded, saved or logged. If you open a .txt file, it is read locally by your browser. Refreshing the page clears everything.
It's safest to avoid them. Some ATS parsers read multi-column layouts and tables in the wrong order or skip text inside them, which can scramble your job history. A single-column layout with standard headings (Summary, Experience, Education, Skills) and simple bullet points is the most reliable choice.
Include every important skill or requirement from the job description that you genuinely have — there's no magic number. Use the employer's exact wording where it's accurate (for example "Node.js" rather than only "Node"), and place keywords naturally in your summary, skills and experience bullets. Stuffing in skills you don't have can get you past a filter but will fall apart in the interview.
It extracts the meaningful words and 2–3 word phrases from the job description, weights them by how often they appear, and checks what share of that weight also appears in your resume, allowing for simple word variants like manage, managed and managing. It's an approximation of keyword matching — real ATS products differ, and some use synonyms or AI ranking.
Yes — copy the text out of your PDF or Word file and paste it in, or save it as a .txt file and open that. Pasting the text is also a useful test in itself: if the copied text comes out jumbled or out of order, an ATS parser may struggle with the same file.
