Google’s New AI Will Revolutionize Your Marketing: 4 Powerful Use Cases

Google has recently launched what might be the most powerful Large Language Model (LLM) and image model available, poised to fundamentally change how businesses approach marketing. After extensive experimentation, we’ve identified four groundbreaking use cases that were previously complex or time-consuming with other AI models. Let’s dive into how you can leverage these tools to elevate your marketing efforts.

To get started, head over to the Google AI Studio, where you can access these powerful models through a free trial. Our first exploration involves a game-changing tool for visual content creation.

1. Create On-Brand Infographics Instantly with Nano Banana Pro

[Example of a professionally designed infographic titled “The Content Reality Check”]

One of the most powerful new features is the ability to generate stunning, high-quality infographics using the Nano Banana Pro image model. As you can see from the example above, the output can be incredibly polished and perfectly aligned with a specific brand’s fonts and color palette.

This was previously a major challenge for AI image generators. Most models struggled with rendering text accurately, often producing spelling errors that were difficult to fix. Furthermore, adhering to a specific brand style was nearly impossible.

Nano Banana Pro excels where others failed. It handles text within images remarkably well and offers professional features like exporting in 4K resolution and selecting various aspect ratios. This makes it perfect for creating compelling visuals for LinkedIn posts, newsletters, or any other marketing channel where visual content drives engagement.

[A detailed system prompt for creating infographics in Google AI Studio]

Although the model is powerful, the key to achieving consistent, high-quality results is providing a clear and detailed system prompt. Instead of endless trial and error, you can create a master prompt that instructs the model on exactly how to design the infographic. Interestingly, providing specific brand details like hex color codes and font names directly in the prompt yields better results than using a reference image, which often leads to the AI copying the structure rather than just the style.

[Generating an infographic based on a LinkedIn post text]

With the system prompt in place, the process becomes simple. Just paste your content—like a LinkedIn post or a newsletter section—into the prompt box. The model will then get to work, transforming your text into a visually compelling infographic that adheres to your predefined brand style.

The result is a custom infographic, like “The Content Marketing Iceberg,” generated in seconds, perfectly matching the specified brand colors and fonts. To streamline this process even further, you can build a simple tool that generates multiple variations at once, allowing you to pick the best design for your needs. This is particularly useful for quickly visualizing concepts for different platforms and formats.

2. Automate Presentations with Excalidraw & Gemini 3

The second powerful use case is creating professional Excalidraw presentations and diagrams automatically. The entire slideshow above, filled with complex diagrams and structured layouts, was generated using Gemini 3.

Excalidraw is a popular virtual whiteboarding tool used for creating diagrams and presentations. Its files are built on a JSON structure, which means a language model like Gemini can be instructed to generate the code for these visuals directly.

[A brain dump of ideas and structure in a Google Docs file]

The workflow is straightforward. Start with a “brain dump” of your presentation content in a text document. This can be an unstructured list of ideas, a transcript from a meeting, or a rough script. This text becomes the source material for the AI.

[05:18.992]

[System instructions for the Excalidraw Creator in Google AI Studio]

Next, use a specialized system prompt that tells Gemini 3 to act as an “Excalidraw Creator.” This prompt instructs the AI to analyze the brain dump, structure it into a logical sequence of slides, and then generate the corresponding JSON code for each slide.

[05:49.192]

Once Gemini generates the JSON, you simply copy it, paste it into Excalidraw, and the slide instantly appears. You can build an entire presentation slide by slide by simply prompting “do the next slide.” This dramatically speeds up the creation of visual aids for videos, webinars, and internal meetings.

3. Build Web Apps and Lead Magnets in Minutes

[Google AI Studio’s “Vibe Code GenAI apps” feature]

The third use case is building quick, functional web applications. Using the Vibe Code Gemini Apps feature in Google AI Studio, you can describe an idea and have Gemini build it. Because the platform integrates Nano Banana Pro (images), Veo 3 (video), and voice capabilities, you can create powerful, visually rich applications with minimal effort.

[07:09.281]

This is incredibly useful for creating lead magnets—free tools that are valuable to your target audience. For example, the chatbot widget app shown above was built with Gemini 3 in under two hours. It serves as a customizable front-end for the often visually plain n8n chat widget, allowing users to connect their webhook, customize the appearance, and embed it on their site.

[08:22.381]

[A Product Requirements Document (PRD) being outlined by AI]

To build an app effectively, start by having Gemini create a Product Requirements Document (PRD). A PRD is a detailed outline of all the features and functionalities of an application. By providing a structured PRD first, you give the AI a clear blueprint, which significantly reduces the back-and-forth and speeds up the development process. Once the PRD is ready, you can feed it into the app builder to generate the final product.

4. Create Interactive and Animated Presentations

Finally, you can create fully interactive and animated presentations or landing pages. Leveraging the same “Build” feature and Gemini’s integration with Veo 3, the AI can generate entire HTML-based slideshows with motion design. We used this to create a dynamic presentation for a webinar, complete with smooth transitions and animations.

[12:17.338]

[The “Build your ideas with Gemini” interface, showing website URLs as input]

The process is similar to the previous use cases. You can provide links to websites as style references and paste in your raw content, such as a webinar script or a brain dump. By giving a few guiding suggestions—like “think very modern” and “use a design-first approach”—the AI will generate a stunning, animated HTML slideshow that you can use immediately.

These are just a few of the many possibilities. By combining these new models with automation tools, you can supercharge your content creation, build valuable tools for your audience, and take your marketing to the next level.
