What you can do with it
- Run design reviews and technical checks (accessibility, performance, responsiveness) on pages the AI has built
- Fix typography, colour, layout and motion with single commands such as polish, typeset and animate
- Try design variants of an element live in the browser and scan for common AI-design flaws without an API key
Make money with it
A freelancer could offer fast website or landing page builds, using the review and polish commands to raise the visual quality of AI-assisted work.
An idea, not financial advice. Check the licence before charging for anything built on it.
Ways a business could use it
- Get more polished, less generic landing pages and web apps from an AI coding tool without hiring a designer for every revision
- Run audits on checkout, settings and marketing pages before launch to catch accessibility and layout problems early
