Tools to automatically improve existing frontend design without rebuilding from scratch?

I’ve been working on a web project and my functionality is solid, but the visual design needs serious help. I’m decent with frontend development but struggle with making things look professional and user-friendly.

I know about tools that generate UI components from scratch, but that’s not what I need. I want something that can take my existing HTML and CSS code and suggest improvements to make it look more polished. Maybe something that could recommend better color schemes, spacing, typography, or layout adjustments.

Basically I’m looking for an AI assistant that focuses on enhancing the visual appearance of working code rather than generating new templates. Has anyone found tools that can analyze existing frontend code and provide styling recommendations or automatic improvements?

this sounds really interesting! have you tried browser dev tools extensions that analyze css? i’m curious - are you more worried about the overall layout feeling dated, or is it specific stuff like color contrast and spacing that bothers you most?

figma’s dev mode is kinda cool! it inspects your site and gives tips on spacing and typography, which is neat. not flawless, but it does point out things like uneven margins and weird font choices that can ruin the look of a site.

I’ve had good luck with design analysis tools that check existing code instead of generating new stuff. Wave and axe DevTools catch accessibility problems and visual hierarchy issues in your markup. For styling, CSS Stats looks at your stylesheets and finds inconsistencies in spacing, colors, and fonts that make things look amateur. Stark’s a browser extension that checks color contrast and suggests better color combos based on what you already have. Run multiple tools - each one catches different stuff. One might spot your wonky margins while another suggests better font pairs. Fixing the technical issues these tools find usually makes everything look way more polished without starting over.
