Most “free” ATS checkers make you create an account before showing a real result — we tested 7 of them and only one worked with zero sign-up (see the full comparison).
So we built our own. Paste your resume text and the job description below, and get an instant keyword match score, the exact terms you’re missing, and 7 structure checks recruiters’ systems actually look at. No account, no email, no upload — everything runs in your browser, and nothing you paste ever leaves this page. If you are starting from scratch, start from a template that parses cleanly.
Copy the text from your resume (Ctrl+A, Ctrl+C in Word/Google Docs) and paste it below. Nothing leaves your browser — the check runs entirely on your device.
Paste the full job posting. The checker pulls the important keywords from it and compares them with your resume.
Fix this first
Keywords from the job description
green = found in your resume · red = missing — add these naturally
Structure checks
Honest note: this is a keyword-overlap estimate, not your real ATS score. Every employer’s system is configured differently, and no online tool can promise you’ll pass. Use the missing keywords and the red checks above as your to-do list — that’s what actually moves the needle.
Privacy: your text never leaves this page. There is no upload, no account, no tracking of what you paste.
Is this ATS resume checker really free?
Yes — unlimited checks, no sign-up, no email, no payment. It runs entirely in your browser.
How accurate is the score?
It’s a keyword-overlap estimate, not your real ATS score. It measures how much of the job posting’s language your resume mirrors, plus 7 structure checks (contact info, section headings, quantified bullets, action verbs, length). Every employer’s ATS is configured differently, so use the missing-keyword list as your to-do list rather than chasing a perfect 100.
Does my resume get uploaded anywhere?
No. There is no server involved — your text is analyzed by JavaScript on your own device and never sent anywhere. You can even disconnect from the internet after the page loads and it still works.
What keywords does it check?
It extracts the most frequent meaningful words and phrases from the job description (filtering out filler words), then checks which ones appear in your resume — including variations like “managed” vs “manage”.
Why is my score low even though I’m qualified?
Usually one of three things: the posting’s exact terms aren’t in your resume (mirror its wording naturally), a structure check failed (missing email, creative section titles, no quantified bullets), or the job description was very short (paste the full posting for a reliable read).
Should I stuff keywords to get 100?
No — keyword stuffing reads badly to humans and modern parsers discount it. Add the missing terms naturally into real bullets and your skills section.
