What is an ATS (Applicant Tracking System)?

An Applicant Tracking System (ATS) is recruitment software used by over 98% of Fortune 500 companies and enterprise employers (like Workday, Greenhouse, Lever, and Taleo). It parses, filters, and ranks candidate resumes based on keyword relevancy, qualifications, and structural formatting before a human recruiter ever sees them.

How does the Nabu Career Free ATS Checker score resumes?

Our ATS algorithm parses both your resume and the target job description. It runs a deep comparative analysis across 5 key pillars: Keyword Alignment (hard skills and industry terminology), Parser & Formatting Safety (tables, columns, fonts), Measurable Impact (metrics and XYZ formula), Section Completeness, and Readability.

What is considered a good ATS score?

A score of 80% or above is considered optimal for passing automated enterprise filters and landing on the recruiter's shortlist. A score between 60-79% may pass if competition is low, while anything below 60% indicates critical keyword omissions or structural formatting errors.

Can the AI rewrite my resume to match the job description?

Yes! Nabu Career features 1-Click ATS Auto-Tailor. Once our scanner pinpoints your missing keywords, our AI intelligently weaves them into your professional summary and experience bullets naturally, without fabricating credentials or stuffing keywords artificially.

Is this ATS scanner really 100% free to use?

Yes. You can scan your resume against any job description, review your full compatibility score, inspect missing technical and soft skills, and preview improvements without any upfront subscription or paywall.
