In their own words
Gamma
Gamma is a visual communication platform for creating presentations, documents, websites, social media, and graphics with an AI agent. Users can begin with a prompt, outline, or file, then refine the result with AI or manual editing. For presentations, Gamma offers text-to-presentation creation, smart layouts, templates, custom themes, and AI-generated visuals. It imports PDF and PowerPoint files and exports to PDF, PowerPoint, PNG, and Google Slides. Projects are private by default and can be shared with selected people, a team, or publicly, with real-time collaboration. Teams can use shared workspaces, templates, brand controls, and custom instructions; Enterprise lists SSO, SCIM, permissions, and admin controls. Gamma has a mobile app but no desktop app. Its free plan costs nothing and allows up to 10 slides per prompt, with PDF and PPTX import and several export formats. Pro lists up to 10 custom domains and Ultra up to 100. Gamma says Business and Enterprise workspace content is excluded from AI training, while individual workspace users can opt out in account settings.
