We built Resume Check AI because no job seeker should have to hand over their resume just to get feedback.
There is no backend database. We literally have nowhere to store your data, even if we wanted to.
Your PDF or DOCX is parsed entirely inside your browser using open-source libraries (PDF.js, Mammoth.js). It never travels over the network.
No signup, no email, no tracking pixel asking who you are. We don't know you and we like it that way.
Results live in your browser tab's session storage. Close the tab → they're gone. Forever.
When you drop a file, JavaScript reads it into memory using the browser's FileReader API. We then run it through PDF.js (Mozilla's open-source PDF library) or Mammoth.js (a DOCX-to-text library) — both of which execute purely in your browser. No fetch, no XHR, no upload.
Our analyzer is a rule-based engine running 100% locally — not a third-party LLM. It checks for ATS-friendly formatting, section presence, action verbs, quantifiable achievements, readability (Flesch Reading Ease), keyword overlap with a job description (if provided), and professional tone signals. Because everything runs on your device, there is no API key, no usage cost, and zero data leakage.
Resume Check AI is a free, browser-based tool built for LinkedIn job seekers who want quick, honest feedback before hitting "Apply." It's intentionally simple — one page, no fluff. Share it with anyone who's job hunting.
This tool provides automated feedback based on common resume best practices. It's a starting point, not a substitute for a human reviewer. Always tailor your resume to the role and have a friend or mentor read it before applying.
