How to Quickly Create GenAI Slide Decks that Impress

✨ Why This Matters

Building great presentations used to take hours — especially when working with complex technical content.

But what if you could transform rough transcripts, screenshots, or blogs into beautiful, professional-looking slide decks in just minutes using GenAI?

That’s exactly what I did — and in this post, I’ll show you how I used Agentic AI and Genspark to create a polished slide deck on a difficult topic (hallucinations in AI), and how you can replicate the same results.

🧰 Tools I Used

📚 What I Wanted to Create

I wanted to explore the concept of hallucinations in large language models (LLMs) — where AI confidently gives you the wrong answer.

My goal: Summarize the topic visually and clearly.

So I collected:

• 🧠 Raw transcripts from Nvidia GTC 2025
• 📊 A slide in Korean presented by KT
• ✍️ Blog insights by Eugene Yan

📝 My Prompt to Genspark

Here’s the exact prompt I gave to generate the slides:

I will give you photos (graphs, tables, etc.) and related content (text) (divided into slides). Then, tie the related content together and create a slide.

1. Simple but visual and beautiful (white background)
2. Visualize pictures (tables, graphs), etc., and clearly highlight the parts that need to be emphasized.
3. Don’t try to include too much content in one slide; keep the text compact and focused.
4. Change the font to Black Han Sans (black gothic), make the title bold, and adjust the thickness of the rest according to importance.
5. In the case of quotations, use italics and font.

🎯 The Result

✅ A professional-looking GenAI-generated slide deck.
✅ Slides were clean, focused, and easy to follow.
✅ It felt presentation-ready — with no extra formatting work.

🧭 How to Do This Yourself

1. Prepare your content and upload them into Genspark – blog post, transcript, article, notes
2. Use a prompt like mine – prioritize layout, visuals, and structure
3. Run through GenAI tools – Genspark – provide links to the blogs if links are available
4. Export – as PDF or PowerPoint, ready to present
