Free AI ATS Resume Checker

An Applicant Tracking System (ATS) is software that companies use to manage job applications. Over 98% of Fortune 500 companies and 75% of all employers use an ATS to filter resumes before a human recruiter ever sees them. The most common systems include Workday, Greenhouse, Lever, Taleo, iCIMS, and BambooHR.

When you submit your resume online, the ATS parses it into structured data — extracting your name, contact information, work experience, education, and skills. It then compares this extracted data against the job description to calculate a relevance score. Resumes that score below the threshold (typically 60-80%) are automatically rejected, meaning the hiring manager never sees them.

This is why formatting matters as much as content. PDFs with complex layouts, tables, headers/footers, images, or non-standard fonts can confuse ATS parsers, causing them to misread or skip entire sections. A resume that looks beautiful in a PDF viewer may be completely unreadable to an ATS.

Our ATS Resume Checker uses the same parsing algorithms that real ATS systems use. When you upload your resume and paste a job description, we extract the text exactly as an ATS would, compare it against the job requirements, and give you a score with specific recommendations for improvement.

Most recruiters set their ATS threshold between 60-80%. This means if your resume scores below 60, it is almost certainly filtered out before a human ever reads it. Our recommendation is to aim for 80 or above for every application. This typically requires tailoring your resume to each specific job description — not using the same generic resume for every role.

The most common reasons for low ATS scores are: missing industry keywords (the job says "React.js" but your resume says "React"), poor formatting (tables, columns, and graphics that break parser extraction), missing sections (no dedicated Skills section, no education dates), and file format issues (submitting an image-based PDF instead of a text-based one).
