I built an AI Resume Optimizer to solve my own job search problem

Like a lot of people, I've been job hunting and got tired of manually rewriting my resume for every single application, never quite sure what recruiters or ATS systems actually wanted to see.

So I built Resume Optimizer: you paste your resume and a job description, and AI tells you exactly what to change to match the role better.

It's a side project, just launched, and I'd love feedback from this community—what works, what doesn't, what you'd want to see added.

Try it here: https://resume-optimizer-sigma-ruby.vercel.app/

Would really appreciate any thoughts, especially from fellow job seekers or anyone who's built something similar!
