Gamma vs SlidesAI (2026): AI decks from a prompt, or AI slides inside Google Slides?
Gamma and SlidesAI both promise decks without design work, but they start from different places. Gamma is the all-in-one presentation maker: describe a topic and it generates a full deck — text, layout, images and themes — that you edit in its own editor. SlidesAI is the Google Slides add-on: write or paste text and it generates slides inside Google Slides, where your team already works. This is the honest head-to-head.
| Gamma | SlidesAI | |
|---|---|---|
| Free tier | Yes — free plan with limited credits and decks | Yes — free plan with limited presentations |
| Paid tier | Paid plans raise credits and add branding and features | Paid plans raise limits and add themes and features |
| Best for | Anyone who wants a polished deck from a prompt, fast | Google Slides users who want AI slides without leaving Slides |
| Standout strength | Full decks from a prompt, with layouts and themes built in | Zero workflow change: AI slides inside Google Slides |
| Watch out for | Template-driven design can look generic without your own story | Design control is thinner than a dedicated deck tool’s |
Gamma’s edge is the finished deck. For a pitch or a talk that needs to look designed from the first draft, its all-in-one generation is the faster route.
SlidesAI’s edge is fit. For teams that already live in Google Slides, generating slides where the deck already lives beats exporting, importing and reformatting.
