About this tool
How to optimize your resume with AI
A generic resume rarely wins interviews. The most effective resumes are tailored to the role: they use the language of the posting, lead with the most relevant experience, and prove impact with numbers. The AI resume optimizer does that systematically.
Upload or paste your resume, choose your target domain, seniority level and company type, and optionally paste the job description. The optimizer returns a before/after score estimate, section-by-section suggestions, a list of domain-specific keywords to add, and concrete bullet rewrites that turn vague duties into quantified achievements. Copy what works, edit it to stay true to your experience, and re-check with the ATS Score Checker.
Your resume is parsed in your browser, and only the prompt is sent to the AI to generate suggestions — nothing is stored on our servers. The optimizer is powered by Google Gemini and free to use within a daily allowance shown on the page.

FAQ
Frequently asked questions
What does the AI resume optimizer do?
It reviews your resume against your target domain, seniority level and company type, then returns concrete improvements: a before/after score estimate, section-by-section suggestions, domain-specific keywords to add, and rewritten bullet points that show measurable impact. Optionally paste a job description for targeted optimization aligned to that exact role.
Is the resume optimizer free?
Yes. You get a number of free AI optimizations per day at no cost and with no account. A counter shows how many you've used. The optimizer is powered by Google Gemini; your resume text is sent only as part of the prompt to generate suggestions and is never stored on our servers.
Will it lie or invent experience?
It's designed to strengthen how you present real experience — sharpening wording, quantifying impact and adding relevant keywords — not to fabricate. Always review every suggestion and keep your resume truthful; only add keywords and claims that genuinely reflect what you've done.
Which domains are supported?
Twelve: cybersecurity, software development, product management, marketing, data science, finance & accounting, human resources, management & leadership, healthcare, legal, sales, and design & UX. Pick the closest match so the keywords and phrasing fit your field.
How is this different from the ATS checker?
The ATS Score Checker is a fast, offline keyword-and-formatting score against a specific job. The optimizer uses AI to actually rewrite and improve your content. Use the checker to diagnose, then the optimizer to fix — they work best together.
