Making slides is the part of any project that quietly drains your soul. You’ve got great ideas, solid research, a real point to make, and then you spend three hours wrestling with boxes that won’t line up. I’ve been there more times than I want to admit.
So when I came across this post from an AI professional breaking down a full slide workflow, I stopped scrolling. The creator makes a bold claim right up top: Claude is still not the best way to build a deck. The winner is Gamma, but only if you run it a very specific way. And honestly, the way this contributor lays it out changed how I think about the whole process.
What I love here is that it’s not vague advice. It’s a repeatable system, step by step, with a reason behind every move. Let me walk you through what the original poster shared.
The exact workflow, step by step
- Start with templates, not a blank prompt. The expert says don’t prompt right away. Head to Templates first, pick one, and click “Create from template.” Their favorite is “Leadership Keynote.” The reason is simple: a template gives Gamma a visual backbone before it ever touches your words, so your content lands inside a design that already works.
- Steal your own content. Go back to Claude where you already worked the topic out, then hit “copy page as markdown.” You did the thinking already. No need to rewrite it. This step turns your existing work into raw material instead of starting from zero.
- Use the left panel, first line. Prompt Gamma with this: “Make a 15-slide deck with the following topic that I’m sharing right after.” Then paste everything under it. The savvy professional points out the why here: this framing tells Gamma the paste is your source material, not a list of instructions to follow. Big difference in output quality.
- Generate 15 slides. Always. The creator is firm on this number. 20 slides is too much, and 15 is the sweet spot. It’s long enough to cover the topic and short enough that nobody’s eyes glaze over.
- Fix the images before you generate. This is the step most people skip. Go to the bottom of the panel, then Visuals, then AI image, then ChatGPT. Set three things: Photos, Texture rich, and Depth of field. Doing this first means your whole deck generates with good visuals baked in, instead of you swapping ugly images one by one afterward.
- Generate, then jump into present mode. Once it’s built, the mind behind this trick says to press “Escape” and change whatever you want. Add an item to a bullet and the slide reflows itself automatically. No manual reformatting.
See why this flows so well? Each step feeds the next. Template sets the frame, your markdown fills it, the prompt framing keeps Gamma on track, and the image settings save you the cleanup grind.
The tip that surprised me most
Here’s the detail I keep coming back to. The original poster notes that Gamma takes up to 100,000 tokens. Their advice: paste the entire conversation. All of it.
That’s a huge context window for a slide tool. Most people paste a short summary and wonder why the deck feels thin. Feeding it the full conversation means Gamma has the depth to pull real substance into every slide, not just headlines.
This industry pro even shared a real use case. They ran exactly this process for a company training on prompting Claude Fable 5.1. Their words: fast, accurate, done. That’s the kind of proof I trust more than any theory.
Why this matters for your work
Think about how many good ideas die on ugly slides. You could have the sharpest insight in the room, but if the deck looks like a cluttered mess, people check out before you make your point. The person who shared this said it best: your ideas are good, so don’t let bad slides be the reason people stop caring.
A few ways you can put this to work right now:
- Team updates: dump your project notes into Claude, clean them up, then run this Gamma flow for a crisp internal deck.
- Client pitches: the template-first approach keeps everything on-brand and polished without hours of fiddling.
- Training sessions: exactly what this contributor used it for, turning a worked-out topic into a teaching deck fast.
- Webinars or talks: 15 slides forces you to tighten your message instead of overloading the audience.
The bigger trend here is worth noticing too. AI tools are getting really good at specialized jobs, and the winners are the ones who know which tool fits which task. Claude for the thinking and the writing. Gamma for turning that into something people actually want to look at. Using each for what it does best is where the real speed comes from.
I was genuinely impressed by how clean and practical this system is. It takes the worst part of presentation work and makes it almost enjoyable. Give it a try on your next deck and pay attention to how much time you save.
