What is an ATS resume checker?

An Applicant Tracking System (ATS) is the software used by 99% of Fortune 500 companies and most mid-size employers to filter resumes before a human ever reads them. When you click "Apply" on Workday, Taleo, iCIMS, Greenhouse, Lever or SuccessFactors, your resume is parsed, indexed, and matched against the job description by an algorithm. If your file doesn't speak the ATS language — right section headers, parsable PDF structure, the keywords the recruiter searches for — it is silently filed away before anyone reads it.

Our free ATS resume checker simulates that filter. In about six seconds it parses your resume locally in your browser, extracts the keywords from the job offer you paste, and gives you a 0-100 match score. You also get the precise list of missing keywords, a six-second recruiter view, a bias detector for sensitive information (age, marital status, photo, address), and a prioritized improvement plan you can apply in minutes.

Unlike most ATS scanners on the market, Similator Pro is genuinely free at the feature level — no scan limit, no credit card, no signup wall on the analysis itself. Resume parsing happens entirely in your browser, so the raw text of your CV never reaches our servers unless you choose to run the AI rewriting step. This privacy-first architecture is unique in the category and is a deliberate design choice.

How the ATS score is calculated

  1. 1.Keyword match (40%)

    We extract weighted keywords from the job description and check their presence in your resume, accounting for stems, synonyms (e.g. "led" ≈ "managed") and section context. Skills in the Experience section count more than skills only listed under Skills.

  2. 2.Section coverage (15%)

    We verify the canonical sections an ATS parser expects: Contact, Experience, Education, Skills. A missing or non-standard heading ("My Career" instead of "Experience") can break parsing for Workday and Taleo.

  3. 3.Readability & format (15%)

    Word count per bullet, bullet length consistency, sentence complexity, presence of dates in a parsable format. Long monolithic paragraphs lose points; quantified bullets (numbers, percentages, dollar amounts) gain points.

  4. 4.ATS compatibility (15%)

    Detection of risky elements: tables, multi-column layouts, decorative icons, non-standard date formats, headers/footers (Workday parser is notorious for ignoring header content). Suggestions are framed as before/after fixes.

  5. 5.Achievement impact (15%)

    Bullets are scored on the STAR pattern (Situation, Task, Action, Result). A bullet like "Led team" scores low; "Led team of 8 engineers to migrate a $2M legacy stack, cutting infrastructure cost 35%" scores high.

ATS resume checker — FAQ

Yes. Every analysis feature on this page is free with no scan limit, no credit card and no signup wall. The optional AI rewriting step uses your own AI provider API key — we never charge a markup. You only pay your AI provider for tokens you choose to spend.
No. PDF and DOCX parsing happens entirely in your browser via WebAssembly. The text of your resume is only sent to an AI provider if you explicitly click "Rewrite with AI", and even then it is sent directly with your personal API key — Similator Pro stores nothing.
The score is calibrated on the public heuristics documented by Workday, Taleo, iCIMS and SuccessFactors parsers, plus benchmarks from Resume Worded, Jobscan and Novorésumé. Two resumes with identical scores will not always rank identically — recruiters add a final human layer — but a score below 60 is a near-certain rejection by the filter.
Because the score is relative to the offer's keywords. A backend engineer resume optimized for a Python role will score 90 against a Python offer and 55 against a Java offer. This is the point: tailor each application.
Above 75 is the sweet spot. Anything below 60 is likely filtered out before a human sees it. Between 60 and 75 you'll be in the bottom of the recruiter's pile; above 85 you're competitive against the top applicants.
Yes. The analyzer auto-detects the language of each input and the AI rewriting step (optional) outputs in the offer's language — useful when applying internationally. Bilingual scanning is built in.
