The Problem
ATS systems scan resumes in milliseconds. A non-standard heading like "My Journey" instead of "Work Experience" causes the section to be skipped entirely.
Creative labels like "My Journey" or "What I Know" confuse ATS parsers trained on standard section names.
Skipping Skills or Summary means ATS never extracts that data — your qualifications disappear.
ATS expects Contact → Summary → Experience → Education. Reversed order disrupts data extraction.
Missing email or phone at the top is one of the most common and most damaging resume mistakes.
Two Skills or Summary sections causes ATS to merge or drop data unpredictably.
A Skills section with one line gives ATS too little signal to accurately score your application.
How It Works
Copy your full resume text and paste it into the tool. No PDF upload needed — just plain text.
Rule-based regex engine scans headings, contact info, ordering, and section content — entirely in your browser.
Get severity-ranked warnings — Critical, Medium, Low — with exact explanations for each issue.
Checks
Every check reflects a real ATS parsing rule that weakens your resume score.
Scans for all 7 standard resume sections: Summary, Experience, Education, Skills, Certifications, Projects, Contact.
Maps creative headings to standard categories. Flags "My Journey" as a non-standard Summary heading.
Generates a 0–100 ATS readiness score. Deducts points per severity: 18 for Critical, 8 for Medium, 3 for Low.
Checks that sections appear in the ATS-expected order: Contact → Summary → Experience → Education → Skills.
Separately detects email, phone, and LinkedIn URL presence anywhere in the resume text.
Counts content lines per section. Warns when a section has fewer lines than the ATS minimum threshold.
