Free resume checker with instant ATS score

A resume checker is a tool that analyzes your resume across multiple dimensions — formatting, ATS compatibility, content quality, and impact — and gives you a score plus actionable suggestions to improve. AtlasResume's free resume checker scores your resume across 4 weighted dimensions and detects 20+ issue types per bullet point with one-click AI fixes.

Yes — AtlasResume's resume checker is free with no sign-up required for the basic ATS score. You get a full 4-dimensional resume analysis covering completeness, content quality, ATS compatibility, and impact metrics. Pro users additionally get one-click AI fixes for every issue detected.

The resume checker analyzes your resume across 4 weighted dimensions: Completeness (30%) checks all sections are filled, Content Quality (25%) analyzes writing strength and verb selection, ATS Compatibility (25%) ensures parsing compatibility with tracking systems, and Impact Metrics (20%) checks for quantifiable achievements like percentages, dollar amounts, and scale.

The ATS resume checker validates: single-column layout, standard section headings (Summary, Experience, Skills, Education), parseable date formats, sans-serif fonts, no tables/text-boxes/headers/footers, keyword density relative to a job description, and content quality signals (action verbs, metrics, no buzzwords). All ATS systems — Workday, Greenhouse, Lever, Taleo, iCIMS — have these requirements.

Checks include: weak/passive verbs, passive voice detection, missing quantifiable metrics, buzzword detection, filler word flagging, first-person pronoun usage, bullet point length, capitalization consistency, punctuation, date format validation, section completeness, skill count, word count, summary length, ATS compatibility, and more — all calibrated to your seniority level.

Critical issues (red) cost 8 points and indicate serious problems like passive voice or missing metrics. Warnings (amber) cost 4 points for moderate issues like weak verbs. Tips (blue) are suggestions that don't affect your score, like style improvements. The resume checker prioritizes Critical issues first so you focus on what moves the needle.

Yes. The resume checker automatically detects your seniority level (junior, mid, senior) and adjusts all thresholds. A junior resume is scored differently than a senior executive's — word count, bullet density, skill count, and summary length all scale with experience. No one-size-fits-all scoring.

Yes. The resume checker updates in real time as you edit your resume. Make a change, see your score adjust instantly — no need to re-run analysis manually. The feedback loop helps you learn what improves your score and apply it across your resume.
