Gamma is an AI-assisted creation tool. You give it a prompt, an outline, pasted text or an existing PDF or PowerPoint file, and it generates designed visual content — primarily presentations and documents, with web pages and social assets also supported.
Its distinguishing design choice is the card: content is generated as stacked, responsive cards rather than fixed 16:9 slides. That is why the same artifact can be presented, published as a web link, or exported to a file format for use elsewhere.
In category terms Gamma sits between three things you may already use. A general-purpose AI assistant drafts the words but not the layout. Presentation software gives you layout control but starts from a blank canvas. Design tools give you visual polish but assume you want to build it yourself. Gamma attempts the middle path: design handled automatically, content still editable.
UK Business Stack classes Gamma as a specialist visual communication layer, not a document system of record and not a replacement for the office suite. It produces artefacts; where those artefacts live, who approves them and how they are presented remain your existing workflow.
