Gamma is a strong tool if your workflow is web-first: quick drafting, clean layouts, and easy sharing.
But if your team lives in PowerPoint (client decks, investor decks, brand-controlled templates), you’ll eventually want:
That’s why teams often look for a Gamma alternative—and why Presentia is a common switch.
| 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 care about | Gamma | Presentia |
|---|---|---|
| Web-native decks and fast sharing | Strong | Good |
| Editing in Presentia before export | Limited | Strong |
| Diagram-heavy / data visuals | Good | Strong with Nano Banana Pro |
| Brand-precise edits in the final file | Harder | Easier in .pptx |
| Hand-offs to clients/teammates in PowerPoint | Can be frustrating | Designed for this |
Gamma’s web format looks great, but teams often hit friction when they need to:
If you do serious iteration, doing that refinement in Presentia Edit mode before export saves hours.
Many presentations rely on structured visuals:
Nano Banana Pro is popular because it tends to produce cleaner “slide graphics” for these use cases.
The fastest workflow is:
.pptxIf step 3 is painful, your tool isn’t aligned with your actual workflow.
Presentia is built around two things Gamma teams often want:
.pptx editability so you can finish in PowerPointIn other words: AI gives you the draft, and your normal PowerPoint workflow finishes the deck.
Numbers change. Labels change. Slide order changes. If visuals are locked, you either regenerate or manually rebuild. Editable .pptx keeps you moving.
When you need specific hex colors, exact spacing, and a template that must be followed, you want slide elements you can format like normal PowerPoint objects.
Frameworks, flows, roadmaps, and charts are where many AI tools fall apart. Nano Banana Pro visuals + PowerPoint editability is a strong combination for these decks.
Here’s a simple 15-minute evaluation:
.pptx and open in PowerPointIf those edits are easy, you’ve found a better long-term workflow.
No—Gamma is excellent for web-first decks and fast sharing. Presentia tends to win when PowerPoint editing and hand-offs matter.
That’s common. Many teams keep Gamma for quick internal decks and use Presentia for client-facing or PowerPoint-heavy work.
No. You can leave them as-is and start using Presentia for new decks.
Yes. It requires a credit card to start, but you won’t be charged until the trial ends. You can cancel before then.
Export one deck and focus on editability: labels, colors, layout, and hand-offs. If those are smooth, you’ll save time on every deck going forward.
