Free ATS Resume Checker
Paste your resume and one job description. JobSealer reads both, lists the requirements it finds in the job, and shows which ones your resume backs with evidence, which it only partly covers and which it does not mention at all.
No sign-in needed. Your text is not saved.
Keep your resume, run the Health Check and export an ATS-safe PDF (the free plan limits the number of exports).
What this check does
You give it two things: the text of your resume and the text of a job description. It reads the job description and pulls out what the employer is asking for: skills, tools, responsibilities and the level of seniority. Then it looks in your resume for evidence of each one.
Evidence is the important word. Each requirement is classified by how well your resume supports it: a skill or tool named in your skills section counts as an explicit match, while a requirement written as a duty (for example "writing SQL queries against relational databases") needs your experience descriptions to show you doing it. The result sorts the requirements into strong matches, partial matches and gaps, and ends with a short summary of the gaps it found.
How to run it
- Pick one real job. Open the posting you actually plan to apply for. A check against a made-up or generic description tells you little.
- Paste the whole job description. Include the responsibilities and the requirements. If you only paste the requirements, the check cannot see what the day-to-day work is.
- Add your resume. Paste the text, or upload a PDF, DOCX, TXT or MD file up to 5 MB. If the upload cannot be read, that is itself useful information: a human-readable file that a tool cannot read is worth fixing.
- Read the three groups. Start with the gaps, then the partial matches. The strong matches are what you already do well; do not rewrite them.
- Decide, then edit. Edit only where you have real experience to show. If a gap is a skill you do not have, that is information about the job, not a prompt to add a keyword.
How to read the result
- Strong matches: your resume supports the requirement clearly: the skill is listed, or your experience shows the work.
- Partial matches: related or indirect evidence exists, but it does not fully show the requirement. These are the cheapest improvements: add the real detail you left out.
- Evidence gaps: the job asks for something your resume does not show. Either you have the experience and left it out, or you do not.
- Recommendations: a short summary of the gaps the check found. The edits themselves are yours to decide.
Before Skills section lists SQL; the experience says only "Worked on reports for the team." The listed skill matches; the duty-style requirement shows as a gap.
After The experience says "Wrote SQL queries against a PostgreSQL warehouse to produce weekly sales reporting." The duty-style requirement now shows as a partial match.
We ran the matcher on these two samples to check this. Use your own true experience; adding wording you cannot back up helps no one.
What an ATS checker cannot tell you
No outside tool can tell you how a particular employer has set up its applicant tracking system. Employers configure these systems differently, and many are used mainly to store applications and let recruiters search them. A score from any checker, including this one, is a comparison of two pieces of text.
A score describes how your resume text lines up with the text of one job description. It is not a prediction of what any employer’s system will do, and it does not guarantee an interview.
The check also has to find the requirements in the posting before it can match them, and it can miss some, especially in long sentences or unusual layouts. A high score does not prove that every requirement is covered, so read the list of requirements it found and compare it with the posting yourself.
What the check is good for is catching real, fixable problems before you apply: a requirement you meet but never wrote down, a skill that sits only in a list, or a file that a tool cannot read.
What happens to your resume
The free check needs no account. Your resume and the job description are analysed to produce the result and are not saved by the check. It uses the same core parser and matcher as the signed-in tools, which do not call an external AI service. There is a short per-minute limit per visitor to keep the service available for everyone.
What this cannot do
- It does not simulate any employer’s own applicant tracking system.
- It does not guarantee an interview, a ranking or an outcome.
- It can miss requirements in a posting, so a high score is not proof that everything is covered.
- Scanned images of text cannot be read; use a text-based file.
Frequently asked questions
- Does a high score mean I will pass an employer’s ATS?
- No. The score compares your resume with one job description. It cannot see how a specific employer has configured its system, and it does not predict a result.
- Do I need an account?
- No. The free check works without signing in and does not save your resume or the job description.
- Is it really free?
- The public check is free and needs no account; it has a short per-minute limit. Other tools need an account, and some features are part of the paid plans. The plans on the home page list what each includes.
- Does a score of 100 mean my resume covers everything?
- No. The score covers the requirements the check could identify in the posting, and it can miss some. Compare its list with the posting.
- Why did it find a gap for a skill I have?
- Usually because the skill is missing from the resume, or appears only in a list with no work behind it. Add the real detail where it belongs.
- Can I check the same resume against several jobs?
- Yes, one job at a time. Different jobs ask for different things, so the same resume will show different gaps.
