You spent hours polishing your resume. It looks great. You hit "Apply"... and hear nothing back.

Sometimes the problem isn't your experience. It's that the software read your resume wrong.

That's why we built the Free ATS Resume Checker on Noloii: paste your resume, paste a job ad, and see exactly what an Applicant Tracking System reads, what's missing, and how to fix it.

What is an ATS (in 30 seconds)?

ATS stands for Applicant Tracking System. It's the software most companies use to collect and search resumes. Well-known examples include Workday, Greenhouse, Lever, iCIMS and Taleo.

Here's the simple flow:

  1. You upload a file with your jobs, skills and contact details.
  2. A parser reads it and sorts the text into boxes: name, email, jobs, skills, education.
  3. A recruiter searches for "Excel" or "React" and sees only candidates who have that word in their profile.

An ATS is closer to a searchable database than a robot judge. But if the parser can't read your file properly, you might never show up in the search at all.

What the checker does

The Noloii ATS Resume Checker compares your resume with a job description in three layers:

1. Readability: can an ATS parse it?

It reads your file the way a parser would and tests whether your name, contact details, sections and dates can be found. It also detects things like two-column layouts, tables, images and links.

2. Match: do your skills fit the job?

It matches your skills and keywords against the posting, giving more weight to required skills and to terms the job ad repeats. You see what you already cover and what's missing.

3. Writing: are your bullets strong?

It reviews action verbs, measurable results and weak phrases, so your bullets show impact instead of just duties.

And the best part for privacy: everything runs in your browser. Your resume and the job description are never uploaded to a server.

How to use it (3 steps)

  1. Add your resume. Paste the text, or upload a PDF, Word or TXT file.
  2. Add the job ad. Copy the whole job post, including the requirements.
  3. Get your fixes. See what's missing and how to fix it, one step at a time.

New here? There are one-click examples for software developer, marketing specialist, registered nurse, customer support, accountant, and warehouse/driver roles, so you can see how it works before using your own resume.

5 resume mistakes that quietly hurt you with ATS

These come up constantly, and they're all fixable.

❌ The stylish two-column template

A parser reads across both columns, so skills end up inside job descriptions and titles get attached to the wrong employer.
Fix: Use a single column. Keep the design in spacing and typography, not layout.

❌ Contact details in the page header

Many parsers ignore headers and footers, so your application can arrive with no email or phone number.
Fix: Put contact details at the top of the body text.

❌ "JS" instead of "JavaScript"

Recruiters search for exact strings. If the posting says JavaScript and you wrote JS, they may not find you.
Fix: Write the full term once, then the abbreviation: JavaScript (JS).

❌ A scanned, image-only PDF

No text layer means the system sees a blank page.
Fix: Export a text-based PDF directly from a word processor. Quick test: open the PDF and try to select and copy the text. If you can't, a parser can't either.

❌ Duties instead of results

"Responsible for month-end close" says nothing about impact.
Fix: "Cut month-end close from 8 days to 5 by automating reconciliations."

A quick formula for strong bullets

Action verb + what you did + how/with what + result

Before After
Responsible for customer emails Resolved 60+ customer emails daily, keeping response time under 2 hours
Helped with the website Rebuilt the pricing page in React, raising sign-ups by 18%
Worked on reports Automated weekly sales reports in SQL, saving the team 5 hours a week

No numbers? Use team size, budget, volume, frequency, time saved, or scope. Just make sure you can defend every number in an interview.

Tailor your resume in 15 minutes

You don't need to rewrite everything. Keep one strong master resume and adjust four high-impact places for each job:

  • Summary/headline: match the target role and your strongest relevant result
  • Skills section: put the job's required tools first
  • Top 3 bullets of your latest role: rewrite them for relevance
  • Job title line: add a clarifying phrase if your official title differs from the market title

Then run it through the resume checker, fix any parsing problems, and save a copy named for the company.

⚠️ Never add a skill you don't have just to raise a score. Interviewers ask about what's on the page.

FAQ

Is my resume stored or uploaded anywhere?
No. The checker analyzes your files in your own browser.

What's a good ATS score?
Treat it as a guide to gaps, not a pass mark. Above roughly 75 usually means strong coverage of the job's requirements and few readability problems. Focus on fixing the listed issues instead of chasing 100.

Does it match what a real ATS shows?
No tool can reproduce every employer's system, and most ATS products don't show candidates a score at all. This checker applies consistent, explainable rules so you can see what to improve.

PDF or DOCX?
A text-based PDF is a safe default. Use DOCX if the posting asks for it. Avoid scanned files.

Does it work for non-tech jobs?
Yes. It covers technology, data, marketing, sales, finance, healthcare, HR, operations, design, education, legal and customer support.

Does it support languages other than English?
It's currently built for English resumes and job descriptions. Layout and readability checks still help in other languages.
