Remember when AI image generators couldn't spell "congratulations" correctly? Those days are over.
Google's Nano Banana Pro (Gemini 3 Pro Image) launched in November 2025 and it's the first AI image tool that actually handles text properly.
For presentation creators, this means infographics with legible labels, slides with correctly spelled headlines, data visualizations where the numbers make sense.
I tested Nano Banana Pro across dozens of presentation use cases. Here's what actually works, what doesn't, and how to get the best results without becoming a prompt engineer.
Quick Summary:
Best for: One-off infographics, hero images, data visualizations with text
Not for: Complete editable decks, collaborative workflows, brand-consistent slide series
Access: Gemini app (free + paid tiers), NotebookLM, Google Slides (Workspace), Google Vids, Alai (with pre-trained design pre-sets)
Key advantage: Actually renders legible text in images - something DALL-E and Midjourney still struggle with
Key limitation: Outputs are flat images, not editable slides (unless you use a tool that's built on top of it)
What is Nano Banana Pro?
Nano Banana Pro is Google DeepMind's latest AI image generation model, built on Gemini 3 Pro. It's the upgrade to Nano Banana (Gemini 2.5 Flash Image) with significantly better reasoning, text rendering, and resolution options.
For presentations, the relevant features are:
Accurate text rendering: Generates legible text in multiple languages and font styles directly in images
Infographic generation: Creates data visualizations where labels actually align with data points
4K resolution: Output at 1K, 2K, or 4K—sharp enough for large screens
Multi-image consistency: Reference up to 14 images to maintain visual style across a deck
Real-time data: When combined with Gemini's search, it can visualize current information
Where to Access Nano Banana Pro
Platform | Availability | Best For |
|---|---|---|
Gemini App | Global (Free + Paid) | Quick image generation |
NotebookLM | Global (All users) | Full slide decks from documents |
Google Slides | Workspace customers | Direct slide creation |
Google Vids | Workspace customers | Video presentations |
AI Mode in Search | US (Pro/Ultra only) | Research + visuals |
Alai, Gamma, Plus AI | Global (Free + Paid) | Pre-trained design pre-sets, no prompt engineering |
How to access in Gemini: Click the banana icon (🍌), select "Create images," then choose "Thinking" for Nano Banana Pro (not "Fast" - that's the older model).
How to Use Nano Banana Pro in Google Slides
Workspace customers get native integration. Two approaches:
Method 1: Help Me Visualize
Open Google Slides
Select "Help me visualize" from the sidebar
Enter your prompt
Insert the generated image
There's also a "Beautify this slide" feature that analyses your existing slide and enhances the design.
Before using Nano Banana Pro: The banana icon on the right sidebar allows you to enter your prompt and create a slide while the ‘Beautify this slide’ button at the bottom re-generates a better-looking slides after analysing your existing one
After using Nano Banana Pro: Results from ‘Beautify this slide’
Method 2: NotebookLM Slide Decks
NotebookLM can convert documents into full presentations using Nano Banana Pro:
Upload your source docs (PDFs, notes, research)
Click "Create slides" or "Create infographic"
Export to Google Slides for editing
NotebookLM uses Nano Banana Pro to convert PDFs/Notes/Documents to infographics or slide decks
This works well for turning research into presentations. The output looks polished, but you can't control layouts or choose between design options.
Example of slides created using NotebookLM
How to Use Nano Banana Pro in PowerPoint
No native integration yet. Two workarounds:
Method 1: Copy-Paste from Gemini
Go to gemini.google.com
Click → "🍌 Create image"
Enter your prompt
Right-click → Copy image
Paste into PowerPoint
Simple but makes it difficult to maintain consistency in designs and requires you to create a new prompt for each slide.
Method 2: Third-Party Add-ins
Plus AI and similar add-ins now include Nano Banana Pro access directly in PowerPoint. Install from the Microsoft Office Add-ins store.
How to Use Nano Banana Pro in AI Presentation Makers
Here's the thing about Nano Banana Pro: the output quality depends almost entirely on your prompt. Vague prompts get vague results.
That's fine if you know prompt engineering. Most people don't.
AI Presentation Makers solved this by building Nano Banana Pro into their presentation tool. Here are the top 4 AI presentation makers using Nano Banana Pro:
Alai
Alai uses Nano Banana Pro with prompts trained on 1,000+ presentations. Instead of writing prompts yourself, you pick a design pre-set and the AI handles the rest.
The best part? You have the option to use current theme context while generating a new slide to ensure the design matches all other slides.
How it works:
Import your content through notes, links, screenshots or files
Click Beautify this slide
Choose a design pre-set - each triggers optimized Nano Banana Pro prompts for that style
Tick the checkmark for “use current theme context” to ensure the designs created match your current theme
And that’s it! You can easily export these slides as a PowerPoint, PDF or trackable link.
Examples of slides created on Alai using Nano Banana Pro
Gamma
Gamma integrated Nano Banana Pro into their Studio Mode for generating images within presentations. The model auto-matches your presentation's theme and handles text rendering.
How it works:
Either choose studio mode while creating a deck (amongst other import options) or select Nano Banana Pro as the model while generating images for slides
Describe what you want or let Gamma suggest visuals
Nano Banana Pro generates images that match your deck's colour scheme and style
Pro users get standard Nano Banana Pro. Ultra users get the HD version with 4K resolution for large-screen presentations.
Examples of slides created on Gamma using Studio Mode (via Nano Banana Pro)
Manus
Manus uses Nano Banana Pro to generate entire slides as images - text, graphics, layouts, everything in one visual. A recent update made these slides editable at the element level.
How it works:
Go to Manus Slides and start a new presentation (specifically select Nano Banana Pro)
Describe your topic, audience, and key messages
Manus generates complete slides using Nano Banana Pro
Edit text or elements directly without regenerating the whole slide
Export as PPTX, PDF, or Google Slides
Free users are limited to 12 slides per presentation. Pro and Team plans remove the limit.
Examples of slides created on Manus using using Nano Banana Pro
Kimi
Kimi combines Nano Banana Pro with their Agentic Slides feature. Upload existing documents and the AI converts them into presentations automatically—no manual content entry.
How it works:
Upload source materials or add your prompt
Kimi's agent analyses/creates the content and structures it into slides
Nano Banana Pro generates infographics and visuals
Edit slides in browser, then export as PowerPoint
Charts become native PowerPoint objects, not screenshots, so numbers and data stay editable after export. One limitation: custom company templates aren't supported yet (apply them after export).

Best Nano Banana Pro Prompts for Presentation Visuals (If You're Using Gemini Directly)
If you prefer the DIY route through Gemini, here's what works:
For Infographics
Template: "Create a [style] infographic showing [data/concept] with [specific elements]. Use [colours]. Include [labels]. 16:9 aspect ratio."
Example: "Create a minimalist infographic showing customer journey funnel: Awareness (100%) → Interest (60%) → Decision (30%) → Purchase (15%). Blue gradient. Include percentage labels. 16:9 aspect ratio."
For Concept Slides
Template: "Create a presentation slide illustrating [concept] using [visual metaphor]. [Style]. Clean background for text overlay."
Example: "Create a presentation slide illustrating digital transformation using interconnected gears and circuits. Modern flat design. White background for text overlay."
For Pitch Deck Visuals
If you're building an investor pitch deck, Nano Banana Pro can generate supporting visuals. But remember: investors care more about clarity than aesthetics. A beautiful image that doesn't communicate your point is useless.
Template: "Create a professional slide showing [metric] with [visualization]. Include the text '[headline]' prominently."
For complete pitch deck structure and strategy, see our guide to creating investor decks that get funded.
Nano Banana Pro Review: Honest Assessment
I tested Nano Banana Pro on infographics, data visualizations, concept slides, and pitch deck visuals. Here's what I found:
What Actually Works
Text rendering is genuinely impressive. This is the standout feature. Where DALL-E gives you "Congradulations" and Midjourney gives you abstract squiggles, Nano Banana Pro produces correctly spelled, legible text. Headlines, labels, annotations are all readable.
Infographics make logical sense. The model understands spatial relationships. Arrows point in the right direction. Timelines flow left-to-right. Comparative elements maintain proper proportions. This matters for data visualization.
Fast generation. Under 10 seconds for standard resolution. Iterating through prompts is practical, not painful.
High resolution holds up. 4K output looks sharp on large screens and in print. Zoom in and details stay crisp.
What Doesn't Work
Not editable (in most implementations). When using Nano Banana Pro through Gemini or NotebookLM, you get flat images. You can't click on the text to fix a typo. You can't move elements. Something wrong? Regenerate the whole thing.
Tools built on top of Nano Banana Pro solve this by keeping your content in editable layers while applying the AI-generated design, so you get the visual quality without losing editability.
Prompt-dependent quality. Vague prompts produce vague results. "Make a nice infographic about sales" gets you something generic. Specific prompts with aspect ratio, colours, and exact text content get you something usable. This is why pre-trained prompts (like Alai's design pre-sets) matter.
Style consistency across decks is hard. Even with multi-image referencing, maintaining the exact same visual style across 15 slides requires careful prompting and often manual curation, unless you're using a tool that handles this for you.

Try different design pre-sets - each triggers different Nano Banana Pro prompts optimized for different styles
Import existing decks to transform them rather than rebuilding from scratch
Check the “use current theme context” to keep consistency in all slides
FAQs
Can Nano Banana Pro create slides?
Yes, but with a caveat.
Nano Banana Pro can generate images that look like slides - complete with titles, bullet points, graphics, and layouts. Prompt it with something like "Create a slide about market trends in renewable energy" and you'll get a polished, presentation-ready image.
The limitation: It's still an image. You can't click into the text and edit it. You can't move elements around. If there's a typo, you have to regenerate the whole thing.
Is Nano Banana Pro free?
Yes, with limits. Free tier in Gemini app has usage caps. Google AI Plus/Pro/Ultra subscribers get higher quotas. Alai's free plan includes access to Nano Banana Pro through their Beautify feature.
Can I edit the images after generation?
Depends on how you access it. Through Gemini directly—no, you get flat images. Through Alai—yes, your content stays editable while the design transforms.
How does Nano Banana Pro compare to DALL-E and Midjourney?
Text rendering is Nano Banana Pro's main advantage. It generates legible, correctly spelled text far better than either competitor. DALL-E and Midjourney may still produce more artistic images for non-text use cases.
What's the difference between Nano Banana and Nano Banana Pro?
Nano Banana (Gemini 2.5 Flash Image) is the standard model—"Fast" option in Gemini. Nano Banana Pro (Gemini 3 Pro Image) is the advanced model with better reasoning and text rendering—"Thinking" option.
Do I need to learn prompt engineering to use Nano Banana Pro?
If you're using Gemini directly, yes, your output quality depends on prompt quality. If you're using Alai, no, their design presets use prompts trained on 1,000+ presentations, so you get professional results without writing prompts.
Which creates better presentations: Nano Banana Pro or ChatGPT?
They do different things.
Nano Banana Pro is an image generation model. It creates visuals - infographics, diagrams, slide graphics with readable text. It's the best AI model for generating images that belong in presentations because it actually renders text correctly (most AI image generators don't).
ChatGPT is a language model that can also generate images (via DALL-E or GPT-4o). It's stronger at writing content, structuring ideas, creating outlines, and drafting speaker notes. Its image generation is decent but struggles with text rendering compared to Nano Banana Pro.
Bottom Line: When To Use Nano Banana Pro
Nano Banana Pro is a genuine step forward for AI-generated presentation visuals. The text rendering alone makes it worth using.
But raw access through Gemini requires prompt engineering skills most people don't have (or want to develop). The smarter play is using tools that have already done the prompt optimization work.
Alai built Nano Banana Pro into their presentation tool with pre-trained design pre-sets - so you get the image quality without the prompt iteration. If you have existing decks that need a visual upgrade or you want Nano Banana Pro quality without the learning curve, that's the fastest path.
Ready to try Nano Banana Pro the easy way? Get started with Alai free - pre-trained design pre-sets, 4 layout options per slide, PowerPoint export in seconds.
