Card-Based Medium as Gamma's Moat
Jon Noronha, co-founder of Gamma, on building AI-powered slides
Gamma is trying to make slides a gateway into a new work product, not win a feature war with PowerPoint. The defensible part is the card based format itself, where content flows like a doc, presents like a deck, and behaves like a lightweight web page. AI gets users past the blank page fast, but the long term value is that teams can keep one artifact for reading, presenting, sharing, and publishing.

Cards remove the fixed 16 by 9 canvas. Instead of squeezing ideas into one screen, a Gamma can expand, collapse, embed video, live apps, tables, and other web content. That makes it better for hybrid work, where one person may present live while others read and click through on their own devices.

This is why AI is the hook, not the moat. Gamma saw viral growth after prompt based creation launched because AI solved activation and the blank page problem. But management consistently frames the staying power as the medium itself, since plain AI deck generation is likely to be copied by Microsoft and Google.

The closest analogue is Notion more than Slides. Notion won by replacing separate docs and lightweight databases with one flexible page primitive. Gamma is aiming for the same kind of wedge in visual communication, while Canva is the other comparison, extending one editing system across many rectangle based outputs.
The next step is for Gamma to turn this card format into the default container for microsites, reports, sales leave behinds, and internal docs, with slides as the on ramp. If that happens, AI generation becomes table stakes, and the company that owns the new medium, the layout system, publishing flow, and reusable content graph captures the durable advantage.
