DECKY VS GAMMA
Gamma is a fast, web-native deck maker for individuals. Decky is an enterprise presentation system that generates on-brand decks inside PowerPoint and Google Slides. Here is how to choose.
The short answer
Gamma is built for speed: type a prompt and get a polished, web-native presentation you can share as a link. It is a strong fit for individuals and small teams who want a good-looking deck quickly and are happy living in Gamma's own format.
Decky is built for organizations. It learns your company's approved templates, fonts, colors, and slide library, then generates new decks from that brand system directly in Microsoft PowerPoint and Google Slides. Admins control what the AI is allowed to produce, so every deck that reaches a customer is on-brand by default.
The core trade-off: Gamma optimizes for individual creation speed in its own format. Decky optimizes for organization-wide brand consistency in the formats enterprises already run on.

Questions
Gamma offers export options, but its decks are web-native, so exported files can lose layout and font fidelity. Decky generates native .pptx and Google Slides files from the start, so there is no conversion step to break.
Decky starts with an implementation step where your templates, brand assets, and slide library become the brand system the AI builds from. After that, creating a deck is a prompt, the same as any AI tool, but every output is already on-brand.
If reps can pick any format, Gamma is quick for one-off decks. If every customer-facing deck must follow the approved template and messaging, Decky is built for exactly that, with an admin layer brand and enablement teams control.
Yes. Decky is free to try for individuals, and enterprise teams can book a demo to see the brand system built from their own materials.
