Free ATS resume checker

The free ATS check that tells you the truth.

Most 'ATS scores' are keyword-density theater that corresponds to no real system — only about 8% of ATS setups auto-reject anyone. TrueFit checks what actually filters candidates: the concrete skills the job names, and the knockout rules — years of experience, degree, work authorization, location.

Paste your resume and the job description and you get the matched skills, the missing ones, any knockout risks, and plain suggestions. You find out why you'd be screened out before you spend an hour applying.

It is worth being precise about what an ATS actually does, because most advice on this subject is built on a myth. The claim that applicant tracking systems automatically reject 75% of resumes has no study behind it — it traces to a 2012 sales pitch by Preptel, a resume-optimisation company that shut down in 2013 without publishing a methodology. In a September–October 2025 study, Enhancv interviewed 25 US recruiters at companies from 100 to 50,000+ employees: 92% said their systems do not auto-reject on formatting, design, missing keywords or a low match score. The 8% who did use auto-rejection applied it only to roles with highly specific hard requirements. Twenty-five recruiters is a small sample and worth treating as indicative — but it is far more evidence than the 75% figure has ever had.

What the ATS really does is parse your document into structured fields — name, contact, employment history with dates, education, skills — which recruiters then search and filter. That is why creative formatting hurts: not because a robot rejects you, but because mangled parsing can make your five years of experience invisible to a filter for "3+ years". Single-column layouts of real selectable text with standard headings parse reliably in every major system; tables, text boxes, images of text and contact details buried in the document header do not.

So the two things that genuinely decide the outcome are the knockout questions and the recruiter's six-to-eight-second scan — and TrueFit is built around exactly those. Knockouts are filterable fields: work authorisation, years of experience, location, on-site expectations. Fail one and the application ends regardless of how strong the rest is, which is why checking them before you invest an hour is the highest-value thing you can do. TrueFit flags them explicitly instead of burying the risk in a percentage.

On keywords, the goal is coverage rather than density. Read the posting, list the concrete skills it names, and make sure every one you genuinely have appears in your resume in the posting's own words — if the job says PostgreSQL and you wrote "relational databases", say PostgreSQL. Never add a skill you don't have; interviews expose it within minutes and some offer letters now allow rescission for misrepresentation. TrueFit shows you the overlap and the genuine gaps so you can fix the wording of things that are true, rather than stuffing terms that aren't.

A comforting number is worse than useless here, which is why we don't give you one. A tool that tells you 87% teaches you nothing about why a recruiter would pass; a tool that tells you "this role wants 5 years and your resume shows 3, and it names Kubernetes which your resume never mentions" tells you what to do next.
