Gamma vs Presenton

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.

Presenton generates editable PPTX and PDF presentations from prompts, documents, and data. Users can edit slides on a canvas or refine them with chat-based AI editing. An existing PPTX can become a reusable design system preserving colors, typography, spacing, and layout rules. The Cloud v3 API accepts prompts, files, URLs, Markdown, JSON, and slide-specific content, and exports PPTX, PDF, and PNG. It supports REST requests, asynchronous jobs, webhooks, and scoped iframe embedding. Self-hosted deployments can use OpenAI-compatible endpoints or local models through Ollama. The desktop application is described as free on Windows, macOS, and Linux with no usage limits; self-hosted/open-source use is free under Apache 2.0. Each generated slide uses one credit. Enterprise deployments can run in customer-controlled cloud, VPC, on-premises, or air-gapped environments, with added access, audit, networking, retention, and support options.
