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.

Notion AI is the artificial intelligence assistant built into Notion, the all-in-one workspace for project management, note-taking, and documentation. It generates content, summarizes documents, answers questions about your workspace, and automates repetitive tasks. Accessible via the /AI command, it leverages multiple models (GPT, Claude, Gemini) to deliver contextualized results directly within your pages and databases. Available as a paid add-on or included in Enterprise plans.
