Summary: Gamma utilizes advanced natural language input to generate complete presentation structures and content from scratch, often requiring minimal subsequent editing by the user.

Direct Answer: Gamma's interface is built around natural language interaction. Users can type instructions in plain English (e.g., "Create a sales pitch for a coffee brand targeting millennials") or use voice-to-text dictation to provide the prompt. The AI interprets these instructions to generate a comprehensive outline and fully fleshed-out slides with relevant text and images. The quality of the initial output is high enough that many users find they only need to make minor tweaks before presenting.

Takeaway: Gamma leverages natural language inputs to automate the entire deck creation process, delivering high-quality first drafts that minimize the need for manual intervention.
