Nano Banana: an AI image editor using natural language cue words

Nano Banana is a program developed by Gemini 2.5 Flash Image model-driven AI image editor. It allows the user to make precise local modifications to an image by entering simple natural language cues, or to generate an entirely new image from scratch. The core feature of this tool is its ability to maintain the consistency of character and scene styles over multiple editing or generation processes. Users can not only modify the local details of the image, such as replacing the background and adjusting the lighting, but also merge multiple images to create a completely new work with a unified style. In addition, all images generated by Nano Banana will include the SynthID invisible watermark to ensure transparency and security of the content. The tool offers free trial credits for new users and is designed to make it easy for both professional designers and users with zero knowledge to bring ideas to life.

Function List

• Text to Image: Users can quickly convert ideas into high-quality images by directly entering text descriptions.
• Cue word driven image editing:: Make precise changes to specific areas of an image without affecting the rest of the image by typing natural language commands such as "change jacket to red" or "add warmth to sunset".
• Maintaining role consistency: The ability to maintain the same character's facial features and style in different outfits, poses, lighting, and scenes ensures the consistency of a series of images.
• Multi-map fusion and style migration: You can blend up to three images together, combine objects, colors and textures from different images, or apply the artistic style of one image to another.
• Scene-aware editing: When adjusting subject poses, lighting, or cleaning up backgrounds, the tool understands and protects the overall structure, depth, and light-shadow relationships of the original scene, making the modified results look realistic and natural.
• Background and object control: Quickly remove or replace objects in an image, clean up the background of a product image, or replace an entire environment in seconds.
• Pose, light and color control: Use natural language to fine-tune character poses, re-light, and change object colors.
• Generate multiple variations: Generate a number of different design options based on a single cue word, or create a set of stylized images around a theme.

Using Help

Nano Banana is a powerful and easy-to-use AI image editing and generation tool that allows you to create stunning AI artwork in three simple steps, even without specialized skills.

Basic use process

1. Step 1: Start creating
   There are two ways for a user to open a project:
   • Upload a picture: Click on the "Edit Image" button and upload a local image that you would like to edit. This can be a photo, illustration or any image you wish to modify.
   • Entering text prompts: If you want to create something from scratch, you can just describe what you have in mind in the input box below "Text to Image".
2. Step 2: Write the prompt
   This is a critical step in bringing your ideas to life. In the cue word (Prompt) In the input box, describe the effect you want to achieve in simple, straightforward natural language. The more specific the description, the more accurately the AI will understand it.
   • For generating images from text: Your description should contain key elements such as subject, background, style, color, etc. For example, "An astronaut riding a horse on Mars with Earth in the background, digital painting style".
   • For editing existing images: Your description should clearly indicate the area to be modified and the specific changes. For example, after uploading a photo of a person, you could enter:"make the jacket red" (turning the jacket red), or "add warm sunset light" (adding warm sunset light).
3. Step 3: Generate and Optimize
   After completing the prompt word, you can set the desired image size, for example1:1,9:16maybe16:9etc. Click the "Generate Image" button and the AI will process your request and generate the result in a few seconds.
   • If you are satisfied with the results, you can export and use them directly.
   • If you are not satisfied, you can return to step 2, modify or add more detailed cue words to further optimize the image, and then generate it again until you get the desired result.

Core Functions

• How do you maintain role consistency?
  This feature is useful when you need to use the same character in different pictures all over a series. You can use prompt words focusing on scene, costume or action changes in subsequent edits or new picture generation after the first successfully generated character picture, and Nano Banana will intelligently recognize and maintain the character's facial features. For example, after generating a frontal portrait, you can continue typing:"a full-body shot of the same person, wearing a black suit, standing in a library" (Full body shot of the same man, in a black suit, standing in a library).
• How do I blend multiple images?
  This function allows you to combine elements or styles from different pictures. In the edit screen, you can upload multiple (up to three) images. Then, describe how you want to blend them in the prompt. For example, upload a picture of an astronaut and a picture of a woman and enter the prompt:"Replace the astronaut on the right with the women and remove the helmet on the astronaut on the left to show the man's face. The two are looking at each other."(Replace the astronaut on the right with this woman and remove the helmet of the astronaut on the left to reveal the male face. The two are looking at each other).
• How do I do local editing?
  This is one of the most powerful features of Nano Banana. You only need to describe in words exactly the area and content to be modified. For example, upload a picture of an indoor home and if you want to change the scene, you can type:"Make woman underwater, and remove the couch and wallpaper"(Keeping the woman underwater and removing the couch and wallpaper.) The AI automatically recognizes and modifies only the appropriate areas, while keeping other elements such as the characters.
