Gamma

Gamma is an AI tool for generating presentations. Give it a topic, outline or article and it generates a laid-out, illustrated deck with a consistent, modern look, usually in under a minute.

Unlike traditional slide software, Gamma is built around “cards”: content adapts to the layout automatically, so you do not have to align text boxes by hand. The same content can also be output as a web page or long document, and you can ask the AI to rewrite individual cards or switch the whole theme in one click.

It is very efficient for internal talks and quick proposals. Layout freedom is lower than PowerPoint, PPTX exports can lose formatting, and CJK font choices are limited.

Key features

• One-step deck generation: Enter a topic or paste an outline or article and get a complete slide structure with content.
• Automatic layout and themes: Built-in themes restyle colours and fonts across the whole deck when you switch.
• AI card editing: Select a card and ask the AI to rewrite it, expand it or present it differently.
• AI imagery: Generates or finds images for each card, cutting down time spent hunting for visuals.
• Multiple formats: Beyond presentations, output web pages or documents, share via link or export files.

How to use

1. Go to the Gamma website, sign up and log in.
2. Start a new presentation and enter a topic, or paste an existing outline or article.
3. Before generating, review the proposed outline, adjust the number of cards and key points, and pick a theme.
4. Once generated, go through each card and fix what you do not like with AI editing or by hand.
5. Share via link or export to PDF, PPTX and other formats — check the layout after exporting.

Best for

• Internal talks and weekly updates: When speed matters more than polish, Gamma produces a respectable deck in minutes.
• Quick proposals and first drafts: Visualise an idea first, then decide whether it is worth polishing.
• Turning articles into slides: When you already have a long piece or report and need a version you can present.
• Online showcase pages: Share as a web link that is easy to read on a phone.

Strengths and limitations

Strengths

• Fast generation with a modern, consistent default design.

• PPTX exports can lose formatting and may need rework.
• Limited CJK font choices; Chinese layouts look less polished than English ones.
