Where Gamma is stronger
Plus creates up to 100 slides from one prompt. Higher plans add 4,000 or 20,000 monthly credits and premium AI image models. Plus raises the limit to 100 slides per prompt.
Where Plus AI is stronger
It creates and edits slides inside Google Slides and PowerPoint. Single slides can be inserted in a chosen format instead of regenerating a whole deck. Tasks typically use 40 to 170 credits, according to its pricing page.
A third option: Siteglade
Neither Gamma nor Plus AI lists mobile apps, desktop apps, browser games and spreadsheets on its pricing page. Siteglade does. Mobile apps for iPhone and Android are built with Expo, previewed in a phone frame and opened on your own phone by QR code, on every plan including Free.
Where Plus AI adds AI to Google Slides and PowerPoint, Siteglade works outside them and delivers the deck as a file, with research and sources. Tasks are processed in the EU on every plan, including Free.
