Gamma

Gamma とは？

Gamma is an AI tool for creating presentations, documents and simple websites. You describe what you need, or paste notes or an outline, and it generates a complete first draft with layout, text and images that you can then edit. It suits founders, marketers, teachers, consultants and anyone who needs good-looking slides without spending hours on design. Gamma uses flexible cards instead of fixed slides, so content can adapt to different screen sizes and be shared as a link. You can restyle the whole deck with a theme, ask the AI to rewrite or expand sections, and export to formats such as PDF and PowerPoint.
