How to Create AI Presentations with Nano Banana Pro: The Complete 2026 Guide

The Fast Way to Make an AI Presentation (That Still Looks Professional)

AI can generate a deck in under a minute. The hard part is getting slides that look presentation-ready: clean diagrams, readable chart labels, and visuals that don’t fall apart on a projector.

That’s where Nano Banana Pro helps. It’s optimized for structured, information-dense visuals (charts, flowcharts, matrices), and Presentia exports the result as a .pptx from the /generate editor.

Current Presentia Workflow (Updated February 24, 2026)

What You’ll Need

• A Presentia account
• A clear topic + audience
• 10 minutes to generate + refine

Optional (but recommended): a brand color palette and your logo for final polish.

What Is Nano Banana Pro (and Why It Matters for Slides)?

Nano Banana Pro is an AI image model designed for presentation-style visuals: charts, diagrams, and infographics where layout and text accuracy matter.

Here’s the practical difference:

Step-by-Step: Creating Your AI Presentation in Presentia

Step 1: Outline the Deck (2 minutes)

Before you generate, write a quick structure:

• Slide count
• Sections (problem, solution, proof, roadmap, etc.)
• Must-have visuals (a market map, a funnel, a timeline, a pricing table)

This gives the AI a target.

Step 2: Use a “Good Prompt” Template

Copy/paste this template:

Topic:
Audience:
Slide count:
Tone:
Must-include slides:
Brand (optional):

Example:

Topic: Series A pitch deck for a B2B SaaS company in healthcare billing automation Audience: healthcare-focused VCs Slide count: 10 Tone: confident, data-driven, simple language Must-include slides: TAM/SAM/SOM, competitive 2×2, pipeline funnel, product architecture diagram, 90‑day roadmap Brand: primary color #8E36E6, clean white background

Step 3: Generate with Nano Banana Pro Enabled

In Presentia:

1. Create a new presentation
2. Paste your prompt
3. Enable Nano Banana Pro / 4K quality
4. Generate

Step 4: Review Like an Editor (Not a Perfectionist)

On the first pass, look for:

• Is the story flow correct?
• Are the key visuals on the right slides?
• Any slide that needs regeneration?

Regenerate only the slides that miss the mark.

Step 5: Export to PowerPoint and Finish There

Download the .pptx and open it in PowerPoint.

This is the big win: you can edit the output like a normal deck—text boxes, shapes, layout, and chart elements.

Prompting Tips for Better Results

• Name the visual format (e.g., “2×2 matrix”, “timeline”, “funnel”, “bar chart”).
• Specify the style (“minimal, white background, purple accent”).
• Keep slide titles concrete (avoid “Overview”, prefer “Market Opportunity”).
• Give numbers if you have them (AI is better at designing when it has anchors).

Examples you can reuse:

• “2×2 competitive positioning matrix. X-axis: automation (low→high). Y-axis: price (low→high). Minimal, clean style.”
• “5-step process flow: Lead → Qualify → Demo → Pilot → Close. Simple icons, evenly spaced boxes.”
• “Timeline with 4 milestones over 90 days. Clean, modern, minimal.”

Common Mistakes (and Fixes)

Mistake: the prompt is too vague Fix: include audience + slide count + must-have visuals.

Mistake: you try to perfect everything inside the generator Fix: generate a strong draft, then export and polish in PowerPoint.

Mistake: brand edits take forever Fix: set theme colors and fonts in the Slide Master first, then adjust individual slides.

Quick FAQ

How long does it take to generate a deck?

Usually 30–60 seconds for a full presentation, and a few seconds for individual slide regeneration.
