What Gemini Nano Banana 2.1 can do in ChatUp

Images from a description

Write the subject, setting, light and style, and Gemini Nano Banana 2.1 turns it into a picture. Change a word or two and run it again until it matches what you had in mind.

Guide it with up to 3 reference photos

Add up to 3 reference photos of your own so a face, a product or a look carries into the new image instead of starting from nothing.

Edit a photo by describing the change

In the AI Image Editor, add a photo and say what should change: a new background, an object taken out, a different style. Gemini Nano Banana 2.1 keeps the rest of the picture as it was.

8 shapes to choose from

Pick 9:16, 16:9, 1:1, 4:3, 3:4, 3:2, 2:3 and 21:9 (tall, wide, square and cinema wide among them), so the image fits a post, a story, a banner or a print before you make it.
