AI Resume Optimization for ATS

ATS resume optimization is tailoring your resume so it passes Applicant Tracking System filters used by most employers. Themis uses AI and research-backed strategies to match keywords, place your job title prominently, strengthen bullet points with action verbs, and hit optimal length—so your resume reaches human recruiters instead of being auto-rejected.

What Is ATS Resume Optimization?

ATS (Applicant Tracking System) software screens resumes before a human ever sees them. Studies show that up to 75% of resumes are rejected by ATS due to formatting issues, missing keywords, or poor structure. Themis helps you beat the bots by optimizing your resume for keyword matching, proper formatting, and research-backed content strategies—so you get past filters and land more interviews.

When you apply to a job, your resume is often parsed and scored by ATS before it reaches a recruiter. Themis analyzes the job posting, extracts critical keywords and requirements, and tailors your resume to match—without fabricating experience. We restructure, rephrase, and strategically place content so both ATS and human reviewers see your best fit for the role.

Themis uses a simple 3-step process: upload your resume, paste the job posting, and download your optimized resume. Each step takes seconds, and most optimizations complete in under 60 seconds.
