Nano Banana Prompt Generator: Smart Image Editing & Prompt Creation

The Nano Banana Prompt Generator is a smart assistant that takes your natural language input and turns it into either: (1) detailed image editing instructions or (2) a complete, ready-to-use image generation prompt. You can upload an image and say exactly what you want to change, or describe a new scene from scratch — Nano Banana understands and structures it for AI image tools.

What Nano Banana Does

• Understands Your Intent: Knows if you want to edit an existing image or generate a new one.
• Clarifies Your Idea: Extracts subject, style, details, and constraints from your message.
• Builds Smart Prompts: Creates clean, structured prompts optimized for AI image generators.
• Crafts Edit Instructions: Turns “make the sky darker and remove the car” into precise edit directions.

How the Nano Banana Prompt Generator Works

1. Input Your Idea: Type what you want in simple language:
   • “Make this image more cinematic with warm lighting.”
   • “Turn this daytime photo into a rainy night scene, keep the person the same.”
   • “Create a fantasy landscape with a crystal castle on a floating island.”
2. Upload or Describe:
   • With image: Upload your image and say which parts to edit.
   • Without image: Describe the image you want from scratch.
3. Smart Understanding: Nano Banana detects:
   • Are you editing or generating?
   • What should stay the same?
   • What should be changed or added?
   • What style, mood, or quality you want?
4. Prompt / Edit Creation: It builds:
   • A precise edit instruction for your existing image, or
   • A complete, well-structured prompt for generating a new image.
5. Copy & Use: Copy the result and paste it into your favorite AI image tool to apply the edit or generate the image.

How to Use the Nano Banana Prompt Tool

• For Image Editing: Upload an image and say exactly what to change, for example:
  • “Change the t-shirt color to red and blur the background slightly.”
  • “Remove the text on the sign and replace it with ‘Grand Opening’.”
  • “Keep the person, but turn the background into a neon cyberpunk city.”
• For New Image Generation: Describe your idea:
  • “Cute 3D banana mascot in a lab coat, white background, clean vector style logo.”
  • “Moody street at night, rain reflections, cinematic lighting, 16:9.”
• Mixed Instructions: You can ask for both:
  • “Use this image as a base but add sci-fi armor to the character and change the background to space.”
• Generate: Click generate to get a polished, AI-friendly prompt or step-by-step edit instruction.
• Pro Tip: Mention what must stay unchanged (e.g., “keep the face the same”) for safer, cleaner edits.
