Gamma is an AI-powered presentation creation tool that automatically generates professional slides from a simple prompt, PDF document, or plain text. Founded in 2020 in the US, Gamma stands out with its document-first approach: instead of building slide by slide, you write your content and the AI transforms it into a visually appealing presentation with layouts, images, and consistent themes. Beyond presentations, Gamma offers a website builder, real-time collaboration, viewing analytics, and flexible export (PDF, PowerPoint, web). The interface is available in 12 languages including French, and AI generation supports over 50 languages. SOC 2 Type II certified, the free plan offers 400 AI credits to get started with no credit card required.

The integrated Chrome extension allows chatting with PDFs directly from the browser without downloads. The unlimited questions system on paid plans eliminates usage restrictions. PDF.ai targets students analyzing academic articles, legal professionals reviewing contracts, researchers exploring scientific literature, financial analysts studying reports, and anyone regularly handling PDF documents. The API available on higher plans enables integration into existing workflows. Team features include collaborator invitations, document sharing, and centralized management.
