I vibe-coded an image converter (JPG/PNG to AVIF/WEBP). The functional tool was ready in just a few prompts.
Then I used Nano Banana Pro 🍌 inside Antigravity to create a logo, and asked the IDE to style the entire tool in Pop-Art, matching the logo design.
A few refinement prompts later, I added the final touches (bulk download and the HTML <picture> code)
A useful tool, fully functional, styled, and built in minutes.
I can share the Github link if you want.
The Gemini 3 Pro + Antigravity combo just blew my mind. 🤯
