Gamma App is an AI-powered presentation tool that generates and enhances professional slides automatically using Claude Opus 4.7. It turns text prompts, documents, videos, and URLs into complete PowerPoint decks with minimal effort.
What is Gamma App?
Gamma App is a web-based AI presentation maker that creates slide decks from plain text descriptions or uploaded files. Input a topic or a PDF, Word document, YouTube link, or existing PPTX, and it outputs a fully designed presentation with layouts, charts, and speaker notes. Built by the Gamma App team, it runs entirely in the browser with no software installation required.
Key Features
- AI PPT Generation — Describe your topic in text and get a complete slide deck with professional layouts, charts, and content. Supports 5-slide default decks with customizable length.
- Slide Beautification — Upload an existing PPTX and let AI redesign the styling — colors, typography, and spacing — while preserving your original content.
- Multi-format Conversion — Convert PDF, Word, Excel, Markdown, plain text, HTML, and YouTube videos into PowerPoint presentations. Each converter preserves source structure (e.g., headings become slide titles).

What can you do with Gamma App?

- Design refresh: Upload a dated corporate PPTX and one-click apply a modern magazine-style preset (e.g., "Ink Classic" with asymmetric spacing and premium tones).
- YouTube to presentation: Paste a YouTube URL and extract key talking points into slides — ideal for summarizing long talks or webinars.
- Reverse-engineer design: Take an existing PPTX, run Reverse Prompt, and reuse its style for new decks to maintain brand consistency across teams.
How does Gamma App work?
Enter a topic or upload a file on the Gamma App website, choose the number of slides and language, then click "Generate PPT." The AI (Claude Opus 4.7) analyzes the input, selects a layout preset, writes slide content, and renders a browser preview. From there you can edit text, swap images, or download the final PPTX. The whole process from prompt to download takes under 2 minutes for a short deck.
