How It Works

Three Steps to a Better Resume

The entire process takes under 2 minutes and gives you a clear, actionable report.

01

Upload Your Resume

Upload your DOCX or PDF resume. Text based files work best, because an ATS needs to read the text.

02

Paste Job Description

Add the job description you are targeting. We analyze keyword alignment, skills, and structure.

03

Get Your ATS Score

Get your match score and the first missing keywords by name. The full list and AI rewrites come with ATSAlign Pro.

What You Get

More Than Just a Score

ATSAlign shows you what to fix, not just a pass or a fail.

Keyword Gap Analysis

See the keywords from the job description that your resume is missing, by name. Free checks show the first two; ATSAlign Pro shows the full list.

Match Score Breakdown

Understand your ATS score across skills, experience, and formatting, not just one opaque number.

AI Resume Optimizer

With ATSAlign Pro, AI rewrites your bullet points to include the missing keywords where they fit what you actually did. It does not invent experience.

Why ATSAlign

Built for How ATS Actually Works

ATSAlign compares your resume with the job description you paste and shows the keywords, skills and formatting issues that matter when recruiters search an ATS. No outside tool can see how a particular employer has set up its own ATS, so treat the score as a guide.

FAQ

Frequently Asked Questions

A resume keyword checker compares your resume against a specific job description and identifies which keywords from the JD are present in your resume and which are missing.
