ATS Resume Checker - Free Resume Scanner & ATS Score

An ATS Resume Checker analyzes your resume against a specific job description and returns a keyword match score from 0 to 100%. According to the Jobscan 2024 ATS Usage Report, 98.4% of Fortune 500 companies use Applicant Tracking Systems to rank candidates before a recruiter reviews them. 22skills performs this check in under 30 seconds using GPT-4o-mini, with Claude Sonnet 4.5 as a fallback, and returns your score plus a prioritized list of missing keywords.

Yes. 22skills provides 1 free ATS scan with no signup and no credit card required. Creating a free account increases the limit to 5 scans per month. Pro costs $14.99/month (or $39 per quarter) and includes unlimited scans and AI-powered resume rewriting — compared to Jobscan at $49.95/month for similar scan volume.

Aim for 70% or higher to clear most automated ATS filters. For senior roles or positions with heavy application volume, target 80% or above. These thresholds reflect how 22skills weights keyword presence, placement, and frequency. A score below 55% typically means the resume is missing multiple required skills listed in the job description. See the full scoring guide at What ATS Score Do You Need?

22skills matches keywords using two methods: exact matching (case-insensitive) and fuzzy matching with a Levenshtein distance of 2 or fewer character edits. This means “Javascript” and “JavaScript” are treated as the same keyword, as are common abbreviations and minor misspellings. The underlying dictionary contains 500+ ATS keywords organized by category, each with synonyms and variations. Keywords flagged as required qualifications in the job description are weighted more heavily in the final score than keywords that appear in nice-to-have sections.

Running a resume check through ChatGPT manually requires copying the job description, copying the resume, writing and refining a prompt, interpreting unstructured output, and repeating as you iterate. The process produces no consistent score and does not track changes across applications. 22skills uses the same underlying AI models (GPT-4o-mini primary, Claude Sonnet 4.5 fallback) but delivers a structured result: a 0-100% ATS score, a matched keyword list, a missing keyword list, and prioritized suggestions — in under 30 seconds. Analysis history is saved so you can track improvements across resume versions.

The most common ATS rejection reasons are: missing keywords from the job description, complex formatting that ATS parsers cannot read (tables, text boxes, multi-column layouts, graphics), non-standard section headers like “Professional Background” instead of “Experience,” and critical keywords with different spelling than the job posting uses. With an average of 250+ applications per corporate role (Glassdoor), these issues are decisive. 22skills identifies all of them in one scan and shows you exactly what to fix.

The best free ATS resume checker scores your resume against a specific job description — not just a generic format grade. 22skills returns a real job-targeted ATS match score (0–100%), your matched and missing keywords, and prioritized fixes on the free tier: 1 scan with no signup, or 5 scans per monthwith a free account. Many alternatives label themselves “free” but only show a generic format score or gate the job-targeted analysis behind a paid plan (Jobscan from $49.95/month, Resume Worded Pro $49/month). 22skills keeps the job-description match — the part that actually predicts whether you pass the ATS filter — free.

Accuracy depends on whether the tool compares your resume to the actual job description. A free checker that only grades formatting misses the main reason resumes get filtered out: missing keywords from the specific posting. 22skills runs the same AI models on the free tier as on Pro (GPT-4o-mini primary, Claude Sonnet 4.5 fallback) and matches against 500+ ATS keywords using exact and fuzzy matching, so a free scan uses the same scoring engine as a paid scan. The only difference is volume: 1 free scan, 5 per month with a free account, or unlimited on Pro at $14.99/month.
