Nano Banana: edit images with AI in real time

At the end of August 2025, Google officially confirmed that its experimental AI visual editing model, known as Gemini 2.5 Flash Image, was real. But by then it already had another name: Nano Banana. Viral on social media, mentioned in forums, protagonist of TikTok videos… and, according to media such as El País, “the biggest challenge to Photoshop in years”.

The key to the commotion? A combination of hyper-realistic editing, extreme speed, and an interface that allows for surprising results just by typing what you want to see. Literally.

Nano Banana represents a new paradigm in visual design: it eliminates the need to master complex tools and allows you to modify images with conversational prompts.

From global hype to real impact in Spain

The Spanish case is particularly illustrative. Here, adoption has been accelerated and diverse. From edits for social media to corporate image tests, users have found immediate and very specific uses: editing a photo of the Mestalla stadium, changing the background of a family image, or creating promotional content without the need for a photo shoot.

This massive reception has been enhanced by its direct integration into the Gemini app—free, multi-platform, and easy to use—which has democratized access to advanced editing technologies. Media such as Wired in Spanish highlight this phenomenon as one of the most effective implementations of AI applied to images.

What Nano Banana can do (and why it’s different)

Nano Banana is not just a pretty tool. Its technical power lies in five key pillars:

Natural language editing: you can delete, add, transform, or stylize objects with simple instructions like “make the background night” or “put a blue sweater on him.”
Record speed: changes are applied in less than 5 seconds, allowing for frictionless iteration.
Conversational memory: you can make several successive modifications without losing the thread.
Visual coherence: it keeps characters, pets, objects intact… even after many changes.
Creative fusion: it combines elements from several photos or applies artistic styles like “anime” or “charcoal portraits.”

This approach makes Nano Banana the first visual AI truly designed for fluid and reactive creation, rather than for simple isolated visual tests.

Are we facing the end of Photoshop?

The headlines announce it as the “Photoshop killer”, but the reality is more nuanced. According to designers and users in Spanish forums, Nano Banana does not replace professional software, but it does complement it. It is ideal for prototyping, sketches, quick content, or proof of concept. For the final finish and granular control, Photoshop is still king.

The interesting thing is that Adobe has understood this perfectly. Instead of competing, it has begun to integrate the Gemini 2.5 model into Firefly and Express, which positions Nano Banana as a technical standard that others want to have within their ecosystem.

How does it compare to Midjourney, DALL·E, or Firefly?

Compared to Midjourney, Nano Banana focuses more on precision and speed than on aesthetic generative art. Unlike DALL·E, it manages to maintain better visual coherence between multiple edits. And compared to Adobe Firefly, its learning curve is almost non-existent, as it is designed to work with conversational prompts in natural language, even from a mobile phone.

In addition, its free availability within the Gemini app has been a key factor in its adoption in markets like Spain.

Real applications in Spain

Nano Banana is being used in multiple sectors, with practical results:

Digital marketing: rapid creation of ads, content for social media, visual A/B tests.
E-commerce: visualization of products in personalized environments without the need for new photo sessions.
Design and prototyping: generation of mockups for architecture, retail, or decoration.
Personal and creative uses: from changing a hairstyle to creating selfies with celebrities.

This accessibility especially empowers SMEs, freelancers, and independent creators to compete visually in a market that until now required technical or budgetary resources that were not always available.

Ethics and security: the other side of innovation

With great power comes… a good usage policy. Google has implemented measures such as SynthID, an invisible watermark for each image generated or edited by AI. In addition, there are active filters that prevent the manipulation of certain images, such as children’s faces or content without explicit consent.

A case cited in Xataka shows how a user was blocked when trying to edit his daughter’s photo to make a passport-type portrait. This reflects active ethical control in the tool, although it also imposes practical limitations.

A revolution (but not for everyone)

Nano Banana is not just another tool: it is a new way of thinking about visual design. Its main contribution is not to replace, but to simplify the creation of quality visual content, facilitating access for professionals, companies, and users without technical experience.

And although it is not yet perfect—there are limits in artistic editing, degradable styles, or restrictions in delicate uses—its evolution and adoption suggest that it will play a key role in the visual future of AI.
