Build AI Content Generator App

I’m looking for a front-end developer who can turn my concept, “AI Content Generator Pro”, into a polished, responsive web application. The idea is simple: give users a clean, professional interface built with vanilla HTML, CSS and JavaScript where they can choose a content type, select a tone, set an audience profile, drop in a few keywords, pick a word count and instantly preview the AI-style copy that appears on screen.

The core work here is the UI and in-browser logic—no server-side processing needed. You’ll wire up the form controls, handle validation, push the input through a JavaScript function that fakes the AI output (placeholder text is fine for now) and update the preview area in real time. I want smooth transitions, tidy component layout and full responsiveness from mobile to desktop.

Deliverables
• A single-page application (HTML, SCSS/CSS, JS) ready to open in any modern browser
• Sleek, professional styling with a focus on usability
• Commented code so I can extend the generator logic later

Once I have the working front end I can plug in my own API calls; your job is to give me the rock-solid foundation and engaging UX that makes the tool feel production-ready.
