Paste your resume and the job description. You'll get a keyword match score and the important terms you're missing — so you can tailor your resume before applying. Runs entirely in your browser; nothing is uploaded.
Most companies run resumes through an applicant tracking system (ATS) that screens for the skills and terms in the job posting before a human ever reads it. This tool pulls the most frequent meaningful keywords from the job description, then checks which appear in your resume. Add the missing ones only where they're genuinely true of you, using the exact wording from the posting — that's what raises your match.
Then build the tailored version in the free resume builder and add a matching cover letter.
