Single-purpose diagnostics that read your resume against one job description and return a specific read in about 27 seconds. Two free runs, no credit card.
Each tool runs the same engine on one focused question: paste the job description, add your resume, and get a verdict with the evidence behind it. For the full four-axis read, run the complete diagnostic. To understand what these tools surface, start with why resumes keep getting rejected and resume filters beyond the ATS.
