Inspiration

As a backend girl, I’ve always been frustrated by how much time is wasted fixing simple UI issues — buttons that don’t align, layouts that break, or text that’s hard to read. It got me thinking: what if the browser itself could act like a helpful co-developer? Something that not only spots problems but fixes them instantly, right where they happen. That “aha!” moment of combining AI with the browser’s native power sparked the idea for Chrome Native UI Copilot.

What it does

Chrome Native UI Copilot detects UI and accessibility problems automatically as you browse and applies fixes instantly. Whether it’s misaligned elements, broken grids, or low-contrast text, the AI can highlight issues and correct them with one click, while also generating developer-ready code patches. It works offline, preserves privacy, and makes web development faster and smoother.

How we built it

We built it as a Chrome extension running AI models directly in the browser. It analyzes the DOM in real-time, detects layout issues, accessibility gaps, and misaligned elements, then suggests or applies fixes automatically. The extension leverages the Chrome Extensions API, Gemini Nano AI, and DOM manipulation libraries to make fixes safe, efficient, and responsive.

Challenges we ran into

  • Detecting UI issues across many types of websites without false positives.
  • Applying fixes that don’t break other parts of the page.
  • Running AI models efficiently in-browser without slowing down performance.
  • Balancing automation with developer trust — users should feel in control. ## Accomplishments that we're proud of
  • Real-time detection and one-click auto-fix for common UI issues.
  • Browser-native AI that works offline and locally, ensuring privacy.
  • Generated patch code that developers can reuse or modify. ## What we learned
  • How to integrate AI directly into the browser to interact with live websites.
  • The nuances of UI/UX problem detection and automated fixes.
  • The importance of privacy, performance, and user trust when running AI locally. ## What's next for Chrome Native UI Copilot
  • Expand to cross-browser compatibility fixes.
  • Add smarter accessibility improvements (WCAG compliance).
  • Explore collaborative debugging where AI assists multiple developers simultaneously.
  • Integrate UX suggestions, such as layout optimization and copy improvements, for an even more intelligent copilot.

Few fun facts on me: backend girl, addidtected to coffe and doesnt know to demo :)
