Google began experimenting with conversational image editing earlier this year in the dev-focused AI studio, but the feature didn't remain experimental for long. Over the summer, Google rolled out the "Nano Banana" image-editing model in Gemini 2.5 Flash. You can use this feature to modify images with just a prompt, and now you don't even need to go to Gemini to use it. Google says Nano Banana is now coming to search, Google Photos, and NotebookLM.
The AI image editor is coming to search via Lens and AI Mode. For Lens, you can simply open the app (iOS and Android) and snap a photo to get started. When the rollout is complete, you'll see a "Create" button at the bottom, with a banana icon. Tap that to enter a prompt, telling the AI how you'd like the photo changed.
When you begin an edit in Lens, the Google app will display the results and offer the chance for follow-up edits in the AI Mode interface. Google is always looking for more ways to get people plugged into its conversational search bot, so there's also a separate way to access Nano Banana there. Simply select the "Create image" tool and enter your prompt to create an image. You can then continue the conversation to have Nano Banana change the image.
