HiretuneHow an ATS reads your resume
When you apply through a company's careers page or a job board, your resume usually lands in an Applicant Tracking System first. The ATS parses your resume into structured text, then scores it against the job's requirements: the titles, skills, tools, and phrases that appear in the posting. Recruiters often review only the resumes that score above a threshold, so a low match can end your application before anyone reads a word of it.
This is why strong candidates get silence. A filter scanned for the right words, came up short, and dropped the resume before a person could weigh in. Checking your match against each job and fixing the gaps is what gets you through.
What your match score means
The checker returns a 0–100 score for how closely your resume matches a specific posting. Treat it as a relative signal, not a grade. A score in the 40s usually means the posting asks for skills and keywords your resume doesn't surface yet. Moving into the 80s generally means you've named the same tools and responsibilities the job describes, using language the parser recognizes.
How to fix the keywords you're missing
- Add the true ones.For each missing keyword you actually have experience with, work it into the bullet where you did that work, in the posting's exact wording.
- Match the job title language.If the role says “Software Engineer” and your resume says “Developer,” align the phrasing where it's honest to do so.
- Drop the formatting that breaks parsers. Columns, tables, text boxes, and skills graphics often read as garbage. Use plain text and standard headings.
- Re-run the check. Confirm the score moved and the gaps closed before you apply.
Doing this by hand for every application is the part that takes about 45 minutes each. Hiretuneautomates it: paste your resume and a job and it rewrites your bullets for the role and drafts a matching cover letter in seconds, without inventing anything.

ATS checker FAQ
What is an ATS resume checker?
An ATS resume checker compares your resume against a specific job description the way an Applicant Tracking System does, then scores how well they match and lists the keywords the posting wants that your resume is missing. It shows you, before you apply, why an automated filter might drop your application.
How does the ATS score work?
The score is a 0–100 estimate of how closely your resume matches the job's requirements and language: the skills, tools, titles, and phrases the posting repeats. A higher score means an ATS is more likely to rank you above the filter threshold and pass you to a recruiter.
Is this ATS checker really free?
Yes. The checker is free and needs no login. Paste a resume and a job and you get the match score and the missing keywords. A free account adds 3 full tailors (a rewritten resume and a cover letter), and Pro is a flat $5/month after that.
What should I do with the missing keywords?
Add the ones that are genuinely true for you, using the posting's exact wording, into the bullets where you already did that work. Don't paste a keyword list or claim skills you don't have. The goal is to phrase your real experience the way the ATS is scanning for it.
Does the checker store my resume or PDF?
No. The free checker reads your text to score it and doesn't save a file. If you create an account, your resume text is stored so you can reuse it, and you can export or delete it anytime from settings.
