Nano Banana AI Tutorial | How to Use Google’s Free Tool (Step-by-Step)

About this video

Kevin introduces Nano Banana, described as Google’s brand-new AI image tool built into Gemini, and shows it is free to try via the Gemini website or the Gemini app on iPhone and Android after signing in with a Google account, selecting Tools > Create Images (the option with the banana icon). He stresses its strength is consistency — a person’s face looks like them across multiple edits. Starting from text, he generates a cookie store on a city street, then iterates in follow-up prompts: renaming the store on the sign to Kevin Cookie Company and making the scene brighter and sunnier, with the storefront and name staying consistent. Uploading a photo of himself (via the plus icon, drag-and-drop, or paste), he uses the viral prompt to turn himself into a 1/7 scale collectible figurine on a desk with toy packaging beside him. He then blends two photos — himself and a jacket — with a prompt to match colours, shadows and textures, and refines further by placing himself in an executive office. He notes unhappy results can be redone and happy ones downloaded full-size from the top right-hand corner, lists other prompt ideas such as 90s sitcom, Wild West, comic book character, removing people, and restoring an old photo, and finally shows the paid Veo 3 route: Tools > Create Videos with Veo, add a Nano Banana image as the starting frame, and animate it into a video.

Key takeaways

• Access Nano Banana inside Google Gemini via Tools > Create Images; no special software beyond a Google account is needed.
• Iterate with follow-up prompts instead of starting over — renames, lighting changes and other edits keep the image consistent.
• Upload a photo and prompt an edit, such as the 1/7 scale collectible figurine with toy packaging, to keep your face recognisable.
• Blend multiple photos by uploading both and prompting to match colours, shadows and textures, then refine the setting in further prompts.
• Extend a still into video with the paid Veo 3 option, using the Nano Banana image as the starting frame.
