New Feature: AI-Powered Prompt Enhancement for Nano Banana

We're excited to announce a powerful new feature for Nano Banana: AI-Powered Prompt Enhancement! This feature uses advanced AI to automatically optimize your text prompts, helping you generate better, more professional-looking images with minimal effort.

What is Prompt Enhancement?

Prompt enhancement is an intelligent feature that takes your simple text descriptions and transforms them into detailed, professional prompts optimized for AI image generation. Instead of manually adding technical details about lighting, composition, and style, our AI does it for you.

Before and After Examples

Simple Input:

a cat sitting on a chair

AI-Enhanced Output:

A fluffy domestic cat sitting gracefully on a wooden chair, 
illuminated by soft golden hour sunlight streaming through a nearby window, 
creating warm rim lighting on its fur and gentle cast shadows on the surface, 
photorealistic style with subtle ambient occlusion and natural depth

Chinese Example:

输入:

一只猫坐在椅子上

增强后:

一只毛茸茸的家猫优雅地坐在木椅上，
柔和的黄昏阳光从窗户照射进来，在猫咪的毛发上形成温暖的轮廓光，
地面上投下柔和的阴影，照片级真实风格，细腻的光影细节和自然景深
