Gamma AI is an intelligent presentation generator that transforms your ideas into professional PowerPoint slides in minutes. Just describe your topic, and our AI handles design, layout, content structure, and even speaker notes — no design skills required.
Core Features
AI PPT Generation
Describe your presentation topic in plain text, and Gamma AI creates a complete slide deck with professional layouts, compelling content, and proper visual hierarchy. Whether it's a startup pitch deck, a training module, or a sales presentation, Gamma AI delivers polished results every time.

PPT Beautification
Already have a presentation? Upload your existing PPTX file and let Gamma AI enhance the design. Our AI fixes layouts, improves typography, applies professional styling, and makes your slides visually consistent — all while preserving your original content.
Speaker Notes Generation
Gamma AI automatically generates detailed speaker notes and talking points for each slide. These notes help you deliver confident, well-prepared presentations without memorizing every detail.
Real-time Preview & Edit
Preview your AI-generated presentation directly in the browser. Click any text to edit it on the fly. When you're satisfied, export to standard PPTX format compatible with PowerPoint, Google Slides, and Keynote.
Free PPT Tools
Gamma AI also offers free tools that anyone can use:
PPT Reverse Prompt
Upload any PowerPoint file and our AI analyzes its design — extracting color schemes, typography, layouts, and visual elements. The tool generates a detailed design style prompt you can use with any AI presentation tool to recreate similar styles.
Use cases:
- Maintain brand consistency across presentations
- Learn from great designs by understanding what makes them work
- Extract client style preferences for design agencies

- Files up to 50MB
- No software installation required
- Developer API available for batch conversion
