Check if your resume is ATS-compatible. Get a score based on formatting, structure, and content quality — with actionable fixes.
An Applicant Tracking System (ATS) is software that companies use to filter resumes before a recruiter ever sees them. Over 90% of Fortune 500 companies use an ATS, and studies show that up to 75% of resumes are rejected by these systems before reaching human eyes. An ATS resume checker helps you understand how your resume performs against these automated filters by analyzing keyword matches, formatting compatibility, and structural organization — giving you a clear picture of what to fix before you apply.
ATS systems work by parsing your resume into structured data and then matching it against the job requirements. They look for specific keywords (technical skills, certifications, tools), evaluate section structure (can it find your experience, education, and skills?), and check formatting compatibility (tables, columns, and graphics often break parsing). The system assigns a relevance score, and only resumes above a threshold get forwarded to recruiters. This means your resume could be perfect for the role but still get filtered if it's not formatted for ATS compatibility or missing the exact keyword phrasing from the job description.
An ATS resume checker analyzes your resume to see how well it would perform in an Applicant Tracking System. It identifies formatting issues, structural problems, and content gaps that could cause your resume to be filtered out before a human ever sees it.
Our checker analyzes formatting structure, section organization, and content quality — the same factors real ATS systems evaluate. While no free tool can replicate every ATS perfectly (there are dozens of different systems), our analysis covers the core factors that matter across all of them.

The most common ATS platforms are Greenhouse, Lever, Workday, Taleo, and iCIMS. They all parse resumes similarly — clean formatting and standard structure matter most regardless of which system a company uses.
Focus on three things: (1) Use standard section headers like 'Experience', 'Education', 'Skills', (2) Avoid tables, columns, headers/footers, and graphics that break ATS parsing, and (3) Use clear, quantified achievement bullets with action verbs.
