The Perfect AI Slide Deck Hack

ChatGPT & Gamma

July 30, 2025

Ever feel like you’re fighting a losing battle trying to get ChatGPT to make a simple slide deck?
I’ve been there. It’s great for research, but when it comes to visual presentations, it often falls flat.

Well, I just saw an incredible post from an AI professional who shared a workflow that totally solves this. It’s so smart because it uses the right tool for the right job.

The expert’s method is a simple two-step process that combines a powerful research AI with a specialized slide generator. Here’s the breakdown:

Part 1: Research in ChatGPT

The author starts in ChatGPT (using the o3 model with search enabled). This is where you do all the heavy lifting for your content.

1️⃣ Start a new chat and prompt it to conduct research on your topic.

2️⃣ Feed it more context. You can add PDFs, Excel files, or any other relevant documents.

3️⃣ Use the magic prompt. Once the research is done, the creator uses this specific prompt to get the perfect output for the next step.

Part 2: Build Slides in Gamma

Now for the magic. You take the brief from ChatGPT and head over to Gamma.app.

1️⃣ Select “Create AI” and then choose the “Paste in text” option.

2️⃣ Paste the brief you just generated.

3️⃣ Let it work! Gamma will create a full, editable slide deck for you in just a minute or two.

I think this is a game-changer because, as the expert points out, it highlights the difference between frontier models (like ChatGPT) and specialized wrappers (like Gamma). One is a jack-of-all-trades, while the other is an absolute master of one thing.

This is just my summary of this brilliant method.
