CheckATS

CheckATS is a free, browser-based ATS resume checker and optimizer designed to help job seekers understand how their resume may perform against a specific job description. Its positioning is practical and transparent: rather than promising a universal ATS score, it combines exact job-description keyword coverage with four mechanical raw-text parseability checks, then offers optional AI review and rewrite features for deeper writing feedback. The primary audience includes active job seekers, software engineers, students, career changers, and bilingual applicants who want fast, actionable resume feedback without creating an account. Core features include local keyword gap analysis, text parseability checks, PDF text extraction, English and Chinese sample support, AI Deep Review, AI Rewrite, and a clean score report. Content features include methodology explanations, resume guides, an FAQ, and references to ATS vendor documentation. The user experience is simple: paste or upload a resume, add a target job description, run the local analysis, and optionally request AI feedback. Technical features include client-side ATS checks, Cloudflare Workers AI, server-side DeepSeek for rewrite, and no browser-entered API keys. AI allowances are 5 reviews and 2 rewrites per IP per UTC day, while local checks are free and require no account. CheckATS emphasizes that its results are directional guidance, not a guarantee of hiring outcomes.
