Nano Banana

1. What it is

Nano Banana is the AI-powered design tool from Google, made to transform ideas into visual content with minimal friction. At its core, it blends generative image intelligence with rapid iteration workflows, making visual experimentation accessible well beyond traditional design roles. 

While many AI tools focus on high-fidelity, production-ready outputs, Nano Banana positions itself as a speed-ideation-first engine. It excels at fast visual ideation, playful experimentation, concept validation, and simpler design needs, which allows marketers, strategists, and content creators in general to explore their ideas without committing to long design production cycles from design teams and agencies.  

It is also very handy for professionals aiming to repurpose branding assets more quickly, as it can learn from previous designs to create new ones.  

At the AI level, Nano Banana emphasizes prompt responsiveness, stylistic flexibility, and variation generation. Users can quickly test multiple visual interpretations of a single idea to understand what resonates before scaling assets into full campaigns. 

From the Positionless Marketing perspective, this means fewer bottlenecks between imagination and ideation. Non-designers can visually express ideas on their own, while experts can use Nano Banana as a rapid sketchpad that accelerates early-stage creative work. 

2. Uses and features

Nano Banana’s value lies in its support for rapid creative exploration. Below are the main ways teams use it: 

• Text-to-image generation: it can turn short prompts into expressive visuals, illustrations, or scenes, optimized for fast iteration.
• Simple variation engine: while previous versions of the tool could struggle to generate multiple visual variations of the same piece, Nano Banana can apply different tones, compositions, moods, artistic, or illustrative styles, keeping the context between them.  
• Refinement feedback loop: quickly adjust wording and constraints to understand how small changes influence the outputs.  
• Multiply branding assets: Nano Banana can learn from other references to create new, consistent pieces. This capability is particularly useful for marketers looking to create new brand assets without relying on the creative team.
• Concept sketching: create early visual concepts for ads, websites, social media campaigns, or presentations by giving Nanobanana references from a moodboard or several images. Say what you like or dislike from each reference to direct the tool to create around specific elements.

3. Try This Prompt Out To...

...create a new brand asset from the ones that you already have! 

**"**Your task is to create a new visual asset that is fully aligned with the brand identity demonstrated in the uploaded references. 

Analyze the uploaded images and internalize: 

• Illustration style
• Graphic design language
• Typography treatment
• Color palette and contrast
• Composition, spacing, and visual rhythm
• Overall brand mood and tone 
  **Do not reinterpret or reinvent the branding**. Stick to what you've learn from the examples and consider the following direction to create the new image: 

Purpose of the new image:

[INSERT PURPOSE HERE — e.g., homepage hero, paid social ad, email header, presentation slide, blog illustration, product launch, institutional branding, etc.] 

Use the stated purpose to determine visual hierarchy, emphasis between text and imagery, level of detail, and emotional tone. The image must clearly serve this communication goal. 

Aspect ratio and/or final dimensions:

[INSERT RATIO OR SIZE HERE — e.g., 1:1, 4:5, 16:9, 9:16, 1080×1080, 1200×628, 1920×1080, etc.] 

Adapt composition, spacing, and focal points to fit this format precisely. Avoid awkward cropping or compressed layouts. 

Exact text to appear in the image:

[INSERT TEXT HERE — headlines, subtitles, CTAs, legal text, disclaimers, footnotes, etc.] 

Text requirements: 

• Preserve exact wording (no paraphrasing)
• Follow the typographic hierarchy and style learned from the reference images, adapted to the ratio aspect of the new image.
• Ensure legibility at the intended size and usage context.
• Integrate text naturally into the layout, respecting margins and negative space.
• If multiple text elements are included, establish a clear hierarchy through scale, weight, and positioning according to the purpose of the image.

Additional restrains:

[INSERT HERE elements that must be included in the new image and the ones that must be kept out – e.g., do not use human figures, don't use black typography, include the brand logo in the right corner] 

4. Common mistakes and limitations

Like all AI tools, Nanobanana has clear boundaries that users should understand to use it properly: 

• Expecting production-ready assets: outputs are great for ideation, but often need professional refinement before use in campaigns or social media posts.   
• Using vague or overly abstract prompts: although Nano Banana can create from short prompts, minimal inputs often lead to generic or random visuals that lack intent, brand consistency, or even logical sense.  
• Relying on the tool "common sense": it is not because some elements "make sense together" that Nano Banana will know that. If you want "a girl set at the table with her legs crossed elegantly", you can't just say "a girl with legs crossed". The result will be compromised.  
• Assuming that the tool will know all brand constraints: without clear complementary guidance, visuals may drift from established brand identity, even when using other images as reference.  
• Limited fine-grained control: it is true that the model has evolved, but precise, detailed adjustments are not its strength yet. It might get confused and generate a completely different thing from the one that you were expecting.  
• Feeding complex instructions all at once: Although Nano Banana can understand several directions at once, trying to get a polished image in a single prompt usually results in bad nonsense results.

5. Tips to avoid mistakes

To get the most out of Nano Banana, pay attention to the next tips! 

• Anchor creativity with intent: clearly describe the message, audience, or emotion you want to explore. Describe the elements that must be on the image and its aspects, the angle, the lightning, and all the details that can be relevant for you to get the best output possible. Expect 8 to 10 interactions to achieve the desired design.
• Generate in batches, then curate: Nano Banana can generate better designs when creating several options for you to choose from, instead of creating one design at a time. Ask the tool to enumerate its creations so that identifying your favorite one is easier.   
• Uploading can help maintain consistency: the tool can sometimes get lost among old interactions and designs created. Whenever you need to use a specific image, especially if it was created a few interactions before, download it and upload it to the chat again. This way, the tool won't get confused about which image you're referring to.
• Use references that show clear patterns: although visual identity manuals allow designers to create different types of images and layouts based on the same color palettes and graphic style, this variety can confuse the tool. Group similar images together to use them as a reference and obtain more accurate results that truly mimic the brand's style.
• One step at a time: it's better to request one change at a time than to ask for everything you want all at once. Asking for too many changes at once can confuse Nano Banana and yield a strange result.
• Document what works: keep track of prompt structures that consistently generate useful results for you. Prompting is not an exact science, and what works on your images and brand can be very specific.

6. When non-experts should call experts

Nano Banana helps non-experts move faster, but certain scenarios still benefit strongly from specialist involvement: 

• When assets directly impact brand perception or sales, professional designers ensure consistency and quality.
• Multi-asset campaigns require cohesive systems that can be prepared by an art director and a design team.
• To guarantee variety, creativity, and novelty for the brand, branding and strategy experts are needed.
• Human creativity, particularly that of advertisers and communicators, remains essential for creating visual narratives rich in nuance and emotional depth.

7. Notes on pricing

Nano Banana typically follows a freemium or low-barrier pricing approach, encouraging experimentation before commitment. Free tiers usually support limited generations, while paid plans unlock higher usage limits, faster processing, or enhanced customization. 

The prices differ for individuals using the Google One platform and for businesses using the Google AI Studio API services. Check carefully which option is best for your case.
