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.
NotebookLM added a video overview feature several months back, which uses AI to generate a video summary of the content you've added to the notebook. The addition of Nano Banana to NotebookLM is much less open-ended. Instead of entering prompts to edit images, NotebookLM has a new set of video styles powered by Nano Banana, including whiteboard, anime, realtor print, and more. The original style is still available as "Classic."
NotebookLM's videos are still somewhat limited, but this update adds a second general format. You can now choose "Brief" in addition to "Explainer," with the option to add prompts that steer the video in the right direction. Although, that's not a guarantee, as this is still generative AI. At least the style should be more consistent with the addition of Nano Banana.
The updated image editor is also coming to Google Photos, but Google doesn't have a firm timeline. Google claims that its Nano Banana model is a "major upgrade" over its previous image-editing model. Conversational editing was added to Photos last month, but it's not the Nano Banana model that has impressed testers over the summer. Google says that Nano Banana will arrive in the Photos app in the next few weeks, which should make those conversational edits much less frustrating.
