editing reality; hidden watermarks; and a frog who can't jump?
This week, we unpack Google’s new tools: Nano Banana, and Storybook; also explore how AI watermarks aim to keep digital media trustworthy.
AI in Action
Editing Reality with Nano Banana [AI Design/Creativity]
Google’s latest tool, playfully named Nano Banana, is drawing attention for how easily it lets anyone edit reality. Available inside the Gemini app and through Google’s AI Studio, it specializes in changing existing photos through natural language commands. Unlike generative tools that dream up entirely new images, Nano Banana works within the photo you already have, and remove, add, or adjust details without reimagining the scene from scratch. Upload an image, type “remove the lamppost,” “brighten the sky,” or “add a dog,” and the change appears almost instantly. Powered by Google’s Gemini 2.5 Flash model, the tool delivers edits that once required professional software, now in seconds.
Its polish comes from the approach Google took. Rather than building another general purpose image generator, the company finetuned Gemini 2.5 Flash specifically for editing tasks. That specialization, combined with a design emphasis on speed and efficiency, makes the experience feel casual rather than cumbersome. A photo edit that once demanded Photoshop skills now happens in a single conversational step. Google also embedded SynthID invisible watermarking from the start, signaling that trust and accountability were part of the launch, not an afterthought.
The result is both powerful and unsettling. Nano Banana makes it easy to erase photobombers from vacation shots or help marketers adapt a single image into multiple campaign styles in seconds. Yet the same qualities like speed, accessibility, and realism that make it so approachable, also make it a potential accelerator of misinformation. The danger is most acute when people are altered in photos, raising questions of reputation, consent, and trust in visual evidence. As the tool spreads, will society be ready to keep pace with edits that blur the line between real and altered?
Bits of Brilliance
What are AI Watermarks? [AI Trust]
As AI generated photos, videos, and text become harder to distinguish from the real thing, the industry is racing to add a layer of provenance: the AI watermark. Instead of a visible logo in the corner, these marks are usually hidden. Some live inside the pixels, others ride along as metadata (the data of your data), like the date, author, or location tag in a photo. A few are presented as visible credentials that travel with the image. The premise is that, if synthetic media carries a reliable signature, platforms, publishers, and regulators gain a way to verify what is artificial and what is not.
Google’s SynthID embeds a fingerprint directly in the pixels, designed to survive common edits such as cropping or compression. OpenAI, Meta, and Microsoft lean more on an industry backed framework that attaches cryptographic metadata to file, while Adobe attaches a visible Content Credentials label that spells out how a piece was made. Each path has tradeoffs. Metadata can be stripped or lost as files move across services, visible labels can be removed or ignored, and invisible marks require detection tools to be widely deployed and routinely checked. None of these methods is a silver bullet, yet together they begin to form an accountability layer for images and video.
The problem is that this layer is fragile. Social platforms like Instagram and Facebook have begun labeling AI generated images when watermarks are detected, but enforcement is inconsistent. Google is experimenting with provenance panels in search, and a handful of news publishers are piloting standards, yet most consumer sites still do not reliably check for signals. Text is even more difficult: watermarking attempts break down under paraphrasing or translation, leaving provenance to disclosure rules or enterprise audit trails. Watermarks only build trust if they are adopted broadly, kept intact as content travels, and surfaced clearly where people encounter media. Without that enforcement, the marks risk becoming a patchwork that bad actors can route around.
Curiosity in Clicks
Gemini’s new storybook feature turns quick prompts into illustrated tales. Open the Gemini app, pick the storybook option, and type a simple idea: a turtle who wants to fly, a robot that learns to paint, a cat who dreams of Mars. In less than a minute, Gemini will generate both pictures and text, stitching them into a mini digital book you can read or share.
This week, I tried it with a story my kids came up with: “Freddie the Frog”, who cannot jump like every other frog. The result was a sweet and uplifting storybook that we all loved. https://g.co/gemini/share/4785919dc09b
Please share your own storybook with me. I’d love to see what you come up with!
