Gamma
Generate presentations, documents, and webpages with AI
Gamma is an AI-powered platform for creating presentations, documents, webpages, and social posts. Gamma's API lets you programmatically generate polished, visually rich content from text prompts, adapt existing templates, and manage workspace assets like themes and folders.
With Gamma, you can:
- Generate presentations and documents: Create slide decks, documents, webpages, and social posts from text input with full control over format, tone, and image sourcing.
- Create from templates: Adapt existing Gamma templates with custom prompts to quickly produce tailored content.
- Check generation status: Poll for completion of async generation jobs and retrieve the final Gamma URL.
- Browse themes and folders: List available workspace themes and folders to organize and style your generated content.
In Sim, the Gamma integration enables your agents to automatically generate presentations and documents, create content from templates, and manage workspace assets directly within your workflows. This allows you to automate content creation pipelines, batch-produce slide decks, and integrate AI-generated presentations into broader business automation scenarios.
Integrate Gamma into the workflow. Can generate presentations, documents, webpages, and social posts from text, create from templates, check generation status, and browse themes and folders.
