HR AI vs. Candidate AI: Building a Resume Customizer in One Evening

HR uses AI to filter resumes. Candidates use AI to write them. Since that's the game, I decided to build a tool to play it properly. I spent one evening building a service that customizes resumes based on job descriptions. You paste the vacancy, upload your resume, and the tool adjusts your highlights to match what their ATS is looking for. It's simple, but it works. I built the whole thing in a few hours, deployed it on Netlify for free, and put it on a subdomain I already owned. Zero monthly cost. Welcome to 2026. Your AI applies to their AI. Somewhere in the middle, a human might get involved, but only if your bot passes their bot's test.
