ATSChecker.ai

ATSChecker.ai is a free online tool that checks how well your resume will perform against Applicant Tracking Systems (ATS). You upload a PDF or DOCX, paste the job description you are applying for, and get a compatibility score in under a minute. The analysis covers keyword overlap, skills alignment, and formatting issues that cause parsing software to misread or discard resumes. No account is required for the first two scans.

The tool processes your resume locally in the browser — your file never leaves your device until you submit it for analysis. The free tier gives you a basic score and summary. The Pro plan ($9.99/month) adds a full ATS report with missing keywords, formatting flags, bullet-point rewrites, and scan history. ATSChecker focuses on what ATS software sees, not what looks good to human eyes. It checks for parseable contact information, clean experience sections, and optimized skills formatting.

ATSChecker is built for job seekers who want to get past automated filters and actually have a recruiter read their application. It is most useful for people applying to roles at large companies that use ATS software, career changers whose resumes may lack expected keywords, and anyone who has sent out dozens of applications with no response. The tool is free to start, with a Pro plan for unlimited scans and detailed reports.
