Gamma.app builds branded decks in 60 seconds

Fighting PowerPoint at midnight to get a pitch deck looking somewhat professional? I used to spend entire Sunday afternoons nudging text boxes by one pixel, hunting for stock photos that didn’t look like stock photos, and crying over misaligned icons. So when I stumbled on this walkthrough from a LinkedIn creator who swears by Gamma.app for AI-generated slides, I had to test every single step.

The original poster makes a bold claim: Gamma is 10x better than ChatGPT for slide generation. After running the workflow myself, I actually agree. And the best part is that this contributor breaks it down into a clean sequence anyone can follow, even if you’ve never touched an AI design tool before.

Here’s the full process, with the reasoning behind each move so you know why it works, not just what to click.

The step-by-step Gamma workflow

1. Head over to Gamma.app. This is the home base. No signup gymnastics, just land on the dashboard and you’re ready to build.
2. Click “Templates” in the top menu. The expert points out that templates are your shortcut to professional structure. Starting from a blank canvas is where most people waste hours.
3. Browse the 100+ ready-made templates. Pitch decks, product launches, team updates, onboarding, investor reports. Each one has been designed by someone who knows layout hierarchy better than you and me.
4. Pick one that matches your brand vibe. The author stresses this step because the template sets the visual tone for everything else. Bold and punchy? Minimal and editorial? Data-heavy? Choose with intent.
5. Click “Use this template.” Gamma loads it into an editable workspace, so nothing is locked down.
6. Paste this prompt:
   

   “Build a [topic] pitch deck. 10 slides. Bold headers. Data-driven visuals.”

7. Choose the ChatGPT image model. The creator specifically calls out this model because it produces the cleanest, most on-brand visuals compared to the defaults.
8. Hit generate and wait about 60 seconds. In that minute, Gamma writes the copy, creates custom images for each slide, and snaps the layout together automatically.
9. Click anywhere on the canvas to edit. This is where the magic of Gamma shines. Swap images, recolor the theme, replace icons, rewrite text, all inline without opening separate menus.
10. Export and share. Done. Move on to the next deck, the next pitch, the next meeting.

That’s roughly a minute of work for something that used to eat an entire evening. I tested it with a fake product pitch and the output was honestly usable as a first draft with almost no edits.

Why each step actually matters

The LinkedIn user frames this workflow as a shortcut, but there’s real thinking baked into the order. Templates first, because structure is harder than content. A focused prompt second, because vague prompts produce vague decks. Image model selection third, because visual consistency is what separates “AI slop” from “real work.” And inline editing last, because polish happens on the canvas, not in a prompt.

If you skip the template step and try to generate from scratch, you end up with generic layouts. If you skip the prompt specificity, you get 20 slides when you wanted 10. Every step in the sequence exists for a reason.

How to make your slides look even better

This is the part that most people miss, and where the original poster’s advice gets really useful. The default theme is fine, but your brand deserves more than fine.

• Don’t settle for the default theme. Every other Gamma user is using it, which means your deck looks like everyone else’s.
• Go to Settings and save your brand kit. This becomes your baseline for every future deck, so you only do the work once.
• Upload your logo, fonts, and color palette. Gamma will apply these automatically across slides, giving you a consistent identity without manual adjustments.
• Add this line to your next prompt:
  

  “Use my brand kit and keep the layout minimal.”

Once the brand kit is in place, every deck you generate looks like it came from a real design team. The savvy professional behind this post calls it “turning a blank prompt into a branded slide in 60 seconds,” and that framing is spot on.

Why I think this matters

Slide creation used to be a bottleneck. Now it’s a 60-second task. If you give pitches, teach, sell, or report on work, the time you save compounds fast.

I was genuinely surprised how much of the workflow came down to templates plus a focused prompt plus a brand kit. Three small decisions, and the output jumps from “AI-generated” to “looks like a real designer built this.”

A few practical use cases where this workflow shines:

• Investor pitch decks when you need a first draft fast and want to iterate on the story, not the layout.
• Internal updates where nobody will read 40 bullet points but a visual deck gets skimmed and shared.
• Client proposals that need to look polished without eating your billable hours.
• Webinar and workshop slides where you’re speaking anyway and the deck just needs to support you visually.
• Course or training material that has to look clean across dozens of lessons.

Give the full walkthrough a read on LinkedIn for the complete context from the person who shared it, and go build your next deck in the time it takes to brew coffee.
