Gamma

Our verdict on Gamma

Gamma is the tool we'd point anyone to for a fast first draft of a deck or a one-pager. In our live test it built a three-card sponsor deck for this podcast in about five minutes, with design good enough that Sam didn't need a graphic designer.

It is not a finished-product machine. You review the text, swap or fix images, and often export to finish elsewhere. In August 2025 Jordan called it the market leader for making presentations quickly, and we have not seen anything on the show change that view.

What we built with Gamma

Gamma was our tool of the week in Episode 10. Sam had paid for it for about a month and a half and had used it only a few times, mostly for one-pagers.

• The brief: a three-card sales deck for Built This Week aimed at sponsors: two tech entrepreneur co-hosts, a tool we built, a tool we use, AI news, about thirty minutes every Friday.
• The result: a styled deck with line-art AI images. Sam thought the first and third slides looked nicely designed. We never told it about Ryz Labs, but it searched the web and pulled in details about the podcast on its own.
• The fix: one image looked off, so Sam used Ask AI to "make it more realistic," and it regenerated that image in place.

Yeah. You can definitely get a skeleton going within seconds that is probably 65, 75, 80% of the way there.

How we use Gamma

1. Write the prompt like a brief. Say who it is for, what it should sell and the key facts. Sam's prompt named the audience (sponsors), the format and the schedule.
2. Set the card count. We asked for three cards, which kept it tight.
3. Edit the outline before generating. Gamma shows titles and sub-bullets first. Fix wording and add cards here. Sam's advice: keep text per card concise and high level.
4. Pick a theme and an image style. You can choose the AI image model and a style such as photorealistic, abstract or line art. We picked line art and a theme closer to our branding.
5. Fix pieces with Ask AI. Click an image or block and chat with it instead of starting over.
6. Read every word. Sam admitted he hadn't read the text during the demo. You should before it goes out.
7. Export to finish. Present from Gamma, or export to PDF, PowerPoint or Google Slides and do the last 20 percent there.
8. Start from a template when one fits. Sam counted well over a dozen, including pitch deck, sales deck and new-employee onboarding.

Where Gamma falls short

• Not perfect yet. Jordan's words in Episode 10. Expect to edit text and swap at least one image.
• Light use on our side. Jordan worked at Amazon, a writing culture, and doesn't make many slide decks. Sam had used it only a couple of times before the demo. We have no long-term data on it.
• No pricing test. Sam has a subscription, but we did not discuss plans or limits on air.

Why Gamma beat the giants

Jordan found it surprising that Google, OpenAI and Anthropic hadn't done AI slides well. When Gamma raised its Series B in November 2025, Sam read the numbers on air: a $2.1 billion valuation, profitable, with about 50 people. Jordan added $100 million in ARR and 70 million users.

Guest Angie Westbrook argued it is more than a PowerPoint replacement:

It's like completely reimagining how you build a slide deck.

— Angie Westbrook, Episode 21

Other tools on the show have made decks too. NotebookLM generated a nine-page slide deck from research in Episode 26, and Sam built a deck in Claude Design in Episode 40. We have not compared them head to head with Gamma.

FAQ

Is Gamma worth it?

For quick decks and one-pagers, yes. Sam said work that used to take hours drops to about an hour or an hour and a half, because Gamma builds a skeleton that is 65 to 80 percent of the way there in seconds.

How do you use Gamma?

Give it a prompt with context, pick the number of cards, review the outline, choose a theme and an AI image style, generate, then use Ask AI to fix individual images or text. Export to PDF, PowerPoint or Google Slides to finish.

Can Gamma export to PowerPoint or Google Slides?

Yes. In Episode 10 Jordan showed exports to PDF, PowerPoint and Google Slides, and you can also present directly from Gamma.

What is Gamma good for besides presentations?

Sam mostly used it for one-pagers, which he said came out looking professional without needing a graphic designer. It also has templates such as pitch decks, sales decks and onboarding decks.
