- Five slightly different buttons, and three grays that should be one.
- Every new screen invents its own spacing and layout.
- A small change in one place breaks something else.
- Empty, loading, error and mobile states nobody asked for, so nobody built.
- The AI tool keeps making new components instead of reusing yours.

How to fix the UI of an app built with Lovable, Cursor or Bolt.
Your app was built fast with Lovable, Cursor, Bolt or v0 and now looks inconsistent and breaks as it grows. What goes wrong, who can fix it, and how.
The short answer
To fix the UI of an app built with Lovable, Cursor or Bolt, you don’t need to start over. You need a design system in your code: one set of colors, type, spacing and components, plus rules your AI tool follows, applied one flow at a time. Baobun Studio does this for $4,000 a month; a front-end developer can help if the problem is mostly the code.
Our take: These tools are great for getting started. The problem is that each screen gets made on its own, so things slowly drift apart. Give the tool a system to follow and most of that goes away.

How a design system fixes it. 03
- An audit of every screen, to find what drifted.
- One set of colors, type and spacing.
- Core components in your code, reused everywhere.
- Rules your AI tool reads, so new screens follow the system.
- Your main flows moved onto it, one at a time.
Where we fit. 04
Our design systems service does this in your code for $4,000 a month: the first month covers the audit, the styles, the core components and a first flow, then it’s month to month. We’ve designed for Booking.com, Serko, Slack and Mux, and the founder designs every project. If your site is in Framer, Webflow or Wix, it isn’t the right fit.
Questions. The ones people ask next.
Email usDo we need to rebuild the app?
Usually not. The system goes into the code you already have, and flows move onto it one at a time.
Can we keep using Lovable or Cursor?
Yes. The system includes rules for your AI tool, so what it builds next matches.
