How to Create AI Presentations with Nano Banana Pro: Generate, Refine & Export

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)
| Step | Where in UI | What happens |
|---|---|---|
| 1. Input | TwoStepHero | Prompt or document text is prepared for generation. |
| 2. Generation | /generate | Slides are created progressively with visible generation progress. |
| 3. Finalize | Edit/Preview + Export | Refine in Edit mode, then export PPTX or PDF from the toolbar. |

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:
| Visual Task | General image models | Nano Banana Pro |
|---|---|---|
| Data charts with labeled axes | ⚠️ Labels often messy | ✅ Cleaner labels |
| Process flow diagrams | ⚠️ Misaligned connections | ✅ More consistent structure |
| Infographics with callouts | ⚠️ Visual clutter | ✅ Better spacing |
| 2×2 matrices / frameworks | ⚠️ Unclear placement | ✅ Clearer layout |
| Projector-ready detail | ⚠️ Variable | ✅ 4K output |
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:
- Create a new presentation
- Paste your prompt
- Set image model to Nano Banana
- 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: Finalize in Presentia Edit Mode, Then Export
Complete final copy, layout, and visual edits in /generate Edit mode.
This is the key workflow: iterate in Edit mode, preview the AI render, then export once the deck is final.
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, refine in Presentia Edit mode, then export.
Mistake: brand edits take forever Fix: choose the closest template/theme before generation, then fine-tune in Edit mode.
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.
Can I edit the deck in Google Slides?
Yes—Presentia exports .pptx, which imports into Google Slides.
Is Nano Banana Pro available during the trial?
Yes. The 7-day trial is meant to let you test generation, refinement, and export end-to-end.
