What is Gamma AI?

Gamma AI is an AI slide creation tool that takes a theme or existing documents and compiles the structure, text, and visual direction of a presentation. The generated draft can be reviewed and edited directly in the browser, and the final result is exported as an editable PPTX file.

Can I create Japanese presentation materials?

Yes. Users enter the theme, audience, purpose, and desired tone in Japanese, and Gamma AI produces a Japanese outline and slide drafts that match the intended use. The site interface also supports English.

Can I use existing documents as source material?

Yes. PDF, Word, Excel, Markdown, HTML, text files, and YouTube content can all be converted into presentation drafts. Format support and file size limits vary by tool page.

Can I edit the generated slides?

Yes. Slides can be reviewed page by page in the browser, and wording or structure can be adjusted before export. The downloaded PPTX file can also be edited further in Microsoft PowerPoint.

Do I need design skills?

No. Gamma AI proposes the initial structure and layout, so users can focus on content. The final result should still be reviewed by the user, and only the parts that need adjustment require manual work.

Is Gamma AI an official gamma.app service?

No. Gamma AI is an independent AI presentation tool and has no partnership or operational relationship with gamma.app. Users should verify facts, figures, and rights before publishing generated content.

Is there a free way to try it?

A presentation draft can be started directly from the home screen without registration. Credit requirements and conditions for PPTX export are described on the pricing page, which users should check for the latest information.

• Describe the theme: Enter the presentation theme, target audience, purpose, and desired tone in plain language, or upload a PDF, Word, or text file as reference material.
• Generate the draft: Gamma AI creates an outline and key points for each slide, then proposes suitable layouts, images, and diagrams for the content.
• Review in the browser: Check the generated slides page by page in the browser and adjust wording, structure, or the number of slides before exporting the deck.
