What is an ATS resume?

An ATS (Applicant Tracking System) resume is a resume specifically formatted and keyword-optimized to pass through automated screening software used by 99% of Fortune 500 companies. ATS software scans resumes for relevant keywords, proper formatting, and standard section headers before a human recruiter ever sees them. ResumeCopy automatically optimizes your resume to score 90+ on ATS systems.

How does the AI resume builder work?

ResumeCopy uses a 3-step process: (1) Paste your current resume and the target job description, (2) AI analyzes the job requirements and rewrites your resume with matched keywords, quantified achievements, and strong action verbs, (3) Your optimized resume is compiled into a professional LaTeX PDF. The entire process takes under 90 seconds.

Is ResumeCopy free to use?

Yes, ResumeCopy is completely free. You only need your own AI API key (from Claude, ChatGPT, or Gemini — all offer free tiers) and an Overleaf account for PDF compilation. Your data is processed in-memory and never stored on any server.

What ATS score should my resume have?

A score of 80+ is considered good, but 90+ significantly increases your chances of getting past automated screening. ResumeCopy's AI is engineered to rewrite your resume targeting a 90+ ATS score by matching JD keywords, using proper section headers, quantifying achievements, and including strong action verbs.

Which AI models does ResumeCopy support?

ResumeCopy supports three leading AI models: Claude Opus 4 by Anthropic (with extended thinking for deep analysis), GPT-4.1 by OpenAI (latest flagship model), and Gemini 2.5 Pro by Google (advanced reasoning). You can switch between providers at any time.

Is my resume data secure?

Absolutely. ResumeCopy processes everything in-memory. Your API keys are stored only in your browser's localStorage and never transmitted to our servers. Your resume and job description are sent directly to your chosen AI provider for processing and are never stored, logged, or shared.
