ATSAlign is a free AI-powered ATS resume checker and optimizer. Upload your resume, paste any job description, and get an ATS compatibility score from 0 to 100 in under 60 seconds — no account required. The tool identifies missing keywords, detects formatting issues that ATS software cannot parse, and shows exactly which skills are creating a gap between your resume and the job description.
An Applicant Tracking System (ATS) is software used by employers to automatically screen job applications before a human recruiter reviews them. Over 98% of Fortune 500 companies and most mid-sized businesses use ATS to filter applicants. If your resume does not contain the right keywords and formatting, it is rejected automatically — regardless of your actual qualifications. ATSAlign simulates this process and tells you exactly what to fix.
ATSAlign uses semantic keyword matching and formatting analysis to score your resume against any job description. It detects missing required and preferred keywords, identifies synonyms and related skills that ATS systems recognize, and flags structural issues like tables, columns, and non-standard section headers that cause parsing failures. The free ATS score analysis is unlimited and requires no signup. AI-powered resume optimization — which rewrites your bullet points to add missing keywords without fabricating experience — is available with a credit purchase.
