JobScan provides match percentages like 72% examples, keyword suggestions such as "stakeholder management" and "agile," plus One Click Optimize for automatic rewrites--at $49.95 per month.
These tools address ATS filtering, where over 99% of Fortune 500 companies use applicant tracking systems that reject many resumes before human review due to poor keyword matches. By aligning resumes with job descriptions, users can improve compatibility. This guide compares Rezi and JobScan, along with workflows and selection tips based on 2026 features and pricing.
