🔹 What is Nano Banana?

Nano Banana is an AI image editing model by Google. It can create or edit images based on simple text instructions.

Instead of doing manual work with brushes and layers, you just tell the AI:

• “Change the background to a night sky full of stars.”
• “Make the shirt green.”
• “Add a mountain behind the house.”

Nano Banana will do the work in seconds.

It saves a lot of time and allows you to be more creative.

🔹 What You Need Before Starting

Before we jump into Photoshop, let’s prepare everything:

1. Photoshop installed (latest version recommended).
2. Replicate account: This is the website that provides access to the AI models. You must:
   • Sign up using your GitHub account.
   • Add at least $10 credit. With this, you can generate about 250 images.
   • Turn off auto-reload so your card isn’t charged automatically.
   • Create an API Token in your Replicate account settings (this is like a password that lets Photoshop connect to AI).
3. Gumroad purchase: Buy the script file (.jsx) from Rob de Winter’s Gumroad page for around $9.
4. Windows/Mac adjustments:
   • On Windows, sometimes antivirus or firewall blocks the script. You may need to disable them temporarily or run Photoshop as Administrator.
   • On Mac, if API issues appear, resetting Photoshop preferences usually solves it.

💡 Keep your internet stable. AI edits are processed online.
