As web developers and designers, we often build websites on big desktop screens and only do a quick resize to check mobile responsiveness. Because of this, subtle mobile UI bugs—like overlapping text, horizontal scroll issues, or broken layouts—often slip into production.

To solve this, I built https://audit.youartz.com — a free Website UI, Mobile Bug & Competitor Clash Engine with AI-powered fix suggestions.

What does it do?
Instead of manually inspecting every element or paying for bulky enterprise suites, you can run a quick audit to check:
Mobile UI & Responsiveness Bugs: Quickly spot layout shifts, viewport overflows, and mobile usability issues.
AI-Powered Fixes (BYOK - Gemini API): Don't just find bugs—fix them. You can plug in your own Gemini API key to get instant, actionable code and UI fix recommendations for the exact issues detected on your site.
Competitor Clash Engine: Put your website head-to-head against a competitor's URL to see how your UI and structure compare.

Why "Bring Your Own Gemini API Key" & Free?
Most site audit tools lock AI insights and competitor checks behind expensive monthly paywalls. By letting you use your own Gemini API key:

Zero Subscription Cost: The core auditing engine is 100% free to use.
Full Control & Privacy: You use your own API quota directly without middleman markups.

Try it out & share your feedback!
I’m actively improving the engine and would love for fellow developers to test it on their own projects.

Run a quick audit on your site, test the Gemini AI fix suggestions, and let me know in the comments if you found any unexpected bugs or have feature requests!
