Why I Don’t Recommend Using Gamma App for Professional Presentations

(especially if you train, coach, teach or consult for a living)

Scrolling through LinkedIn last Saturday I spotted three unrelated posts that used almost identical Gamma slides. That moment confirmed what I keep telling participants in my Generative AI workshops: speed is not the same as quality. Below is a deeper look -

grounded in recent user reviews and expert commentary - at why Gamma’s “one-click deck” isn’t ready for rooms where reputation and revenue are on the line.

10 Quality Gaps You Can’t Ignore

1. No personal voice: Your slides should sound and feel like you. Gamma drafts read like a neutral brochure and strip away style, humour and brand tone.

2. Surface-level insight: AI assembles facts but misses nuance, context and lived experience—key for trainers and consultants who charge for expertise.

3. Repetitive, template-driven look: After a few decks audiences start recognising the same layouts, reducing impact and perceived effort.

4. Visuals often miss the point: Stock-style images or AI art can feel random and sometimes sit in odd places, breaking the flow instead of enhancing it.

5. No crafted story arc: A session that changes minds needs setup-build-payoff, not disconnected bullet lists; Gamma provides structure, not narrative.

6. Weak audience targeting: Corporate board? High-school class? Same deck. You still have to rewrite tone, depth and examples yourself.

7. Limited persuasive power: Slides stay factual and neutral; they rarely build tension, address objections or use rhetorical devices that drive action.

8. Export headaches: Moving to PowerPoint or PDF can crop elements or break sizing, forcing re-work in another tool.

9. Brand alignment is shallow: Fonts, colour codes and layout grids are locked down, so strict corporate guidelines are hard to meet.

10. Time savings shrink after draft one: You’ll still spend valuable hours rewriting copy, rearranging visuals and fixing exports -work you thought AI would remove.

    
    

Where Does That Leave AI in Slide-Creation?

I’m pro-AI when it augments thinking - idea generation, outline drafting, quick visual concepts. I’m anti-autopilot when a tool pretends to replace craft, strategy and credibility. Gamma sits firmly in the second camp today.

Take the Skilled Route: Human-AI Collaboration

If you’re a trainer, lecturer, coach or consultant, your deck is often the first proof of your authority. Instead of outsourcing its soul to a generic generator:

1. Start with your own story and structure.

2. Use AI for targeted tasks - e.g. proposing analogies, rewriting a dense paragraph, producing placeholder icons.

3. Apply professional design standards (contrast, hierarchy, brand rules).

4. Rehearse and refine until every slide earns its spot.

That workflow is exactly what I teach in my Generative AI for Presenters programme. Participants leave with a repeatable process that keeps creation time low without sacrificing personality, depth or persuasion.
