🔖 ATS Checker Bookmarklet

Score your resume against any job posting in one click — no copy-paste, no browser extension, no install screen.

🔒 Reads the page text only · sends nothing anywhere · 100% client-side

What it does. Most ATS checkers make you copy the job description, switch tabs, and paste it. This skips all of that. Open any job posting, click the bookmark, and the free ATS Resume Checker opens with the job description already filled in — you just paste your resume and hit check.

How to install (2 seconds). This isn't an extension — it's a bookmarklet: a normal bookmark whose link is a tiny piece of JavaScript. Drag the green button below onto your bookmark bar. That's the whole install. (Press Ctrl/Cmd+Shift+B first if your bookmark bar is hidden.)

Supported sites. It auto-detects the job-description block on LinkedIn, Indeed, and Greenhouse, and falls back to the page's main content on most other job boards. If a site isn't recognized, it grabs the page text so you can trim it — see the fallback note below.

Tested on

Selector cascade last reviewed: 27 May 2026. Job boards change their markup occasionally — if a site stops auto-filling, the fallback still grabs the page text.

If your site isn't supported

No problem — the bookmarklet still opens the checker with whatever text it found. If it grabbed too much (nav menus, footers), just delete the extra lines in the job-description box before scoring. Or skip the bookmarklet entirely: open the ATS Resume Checker and paste the job description by hand. Same result, one extra copy-paste.

Is it safe? (yes — here's exactly why)

The bookmarklet runs in the context of whatever page you're on (LinkedIn, Indeed, etc.), but it does exactly one thing: it reads the visible job-description text and redirects your own browser tab to this checker with that text in the URL. It does not send your data to any server, read your LinkedIn account, touch cookies, or post anything. There's no tracking and no network call — just a tab redirect you can watch happen.

Don't take our word for it — the entire code is right here, ~370 characters of plain JavaScript:

javascript:(function(){function g(s){var e=document.querySelector(s);return e&&e.innerText.trim()}var t=g('.jobs-description__content')||g('#jobDescriptionText,.job-snippet')||g('.job__description,article[data-test=job-description]')||g('main')||document.body.innerText;location.href='https://hugounoclaw.github.io/ats-checker/?jd='+encodeURIComponent(t.slice(0,1800))})();

The scoring itself also runs entirely in your browser — your resume never leaves your machine, by design.

Want the manual version?

No bookmark bar (mobile, locked-down work laptop)? The checker works the classic way too — paste the JD yourself.
