I got laid off and started testing AI resume tools. Most of them rewrote my experience or added things I never did. So I built one that doesn't.

Resonn helped me stop sending the same resume to every internship. I can tailor it to the actual job description without rewriting everything from scratch.
The biggest difference for me was that the resume still sounded like me. It didn’t come back full of generic AI language.
The interview prep was way more useful than generic interview questions. The questions were based on the actual position I was interviewing for.
I was applying to a lot of jobs and getting nowhere. Resonn helped me focus on better-fit positions and improve how I presented my experience.
I hate writing cover letters. Resonn got me through one quickly and gave me something I was actually comfortable sending.
Resonn feels more like having someone help you through the entire job search instead of just having an AI resume writer.
