Formatting Checks
Detects images, tables, columns, headers/footers, and non-standard fonts that can cause ATS parsing failures.

Is the ATS check really free?
The deterministic ATS scan (keyword matching, formatting check, section structure) is completely free. AI-enriched analysis with personalized suggestions costs 1 credit ($0.10-$0.20).
How accurate is the ATS score?
Our checker uses the same parsing algorithms as popular ATS systems (Workday, Lever, Greenhouse). The keyword match rate directly correlates with your chances of passing automated screening.

Resume Scan checks compatibility with all major ATS: Workday, Taleo, Lever, Greenhouse, iCIMS, BambooHR, and SmartRecruiters. The formatting rules are universal across systems.
Can I check multiple job descriptions?
Yes. You can run unlimited free scans against different job descriptions. Each scan shows a separate match score and keyword gap analysis.
What makes a resume fail ATS?
Common ATS failures: using images/graphics, tables with merged cells, non-standard section headings, missing keywords from the JD, fancy fonts, headers/footers with contact info, and multi-column layouts that parse incorrectly.
How do I improve my ATS score?
Add missing keywords from the job description (use exact phrasing), use standard section headings (Experience, Education, Skills), choose a single-column layout, and remove images/graphics.
