What this checker catches (and why it matters)
Before a recruiter sees your resume, an applicant tracking system parses it into a structured profile. Our study of all 503 S&P 500 careers pages found Workday alone screens ~30% of large-company applications — and each parser has specific failure modes: tables and multi-column layouts get scrambled, creative section headings break field mapping, and missing job-description keywords push you down recruiter search results.
This checker tests the rules that are deterministic — structure, formatting risk, content patterns, and keyword coverage. For the judgment calls (rewriting weak bullets, weaving keywords in naturally, tone), our AI optimizer takes over where rules stop.

Frequently asked questions
- Is this resume checker really free?
- Yes — completely. The check runs instantly in your browser with no account, no email, and no usage limit. We make money from our separate AI optimizer, which rewrites your resume for a specific job; that has a free trial of 10 generations if you want to go further.
- Do you store or upload my resume?
- No. The analysis runs entirely in your browser using JavaScript — your resume text is never sent to our servers, stored, or used for training. You can verify this in your browser’s network tab: clicking "Check my resume" makes no network request with your text.
- What does the checker actually test?
- Over 20 deterministic rules across four areas: contact info and section structure an ATS can parse (email, phone, standard headings, date formats), content quality (bullet usage, action verbs, quantified achievements, clichés), formatting risks that break ATS parsers (tables, multi-column artifacts, unusual symbols), and — if you paste a job description — which of its top keywords your resume is missing.
- How is the score calculated?
- Each rule scores pass, partial, or fail, and rules are grouped into weighted categories. With a job description, keyword match counts for 30% of the total. The score is deliberately rule-based and reproducible — the same resume always gets the same score, unlike AI-only checkers that vary run to run.
- Is an ATS really rejecting my resume automatically?
- Mostly no — that’s a myth. ATS software rarely auto-rejects; what actually happens is your resume parses badly (broken sections, missing keywords), so you rank low in recruiter searches and never get seen. Our study of 503 S&P 500 careers sites found Workday alone handles ~30% of large-company hiring, and each parser has different failure modes. Fixing parseability and keywords is what moves you up.
