A content source gives Presenton the subject matter for a deck. Your brief tells it what result to create; supporting material supplies the facts and detail. ## Choose the right input | Source | Best for | Prepare it by | | --------------------- | ------------------------------------------- | ----------------------------------------------------------- | | Prompt or brief | A new deck based on a clear idea | Naming the audience, goal, scope, and tone | | Documents | Summaries, proposals, training, or research | Removing irrelevant pages and identifying must-use sections | | Structured data | Reports and repeatable automation | Using consistent fields, labels, units, and date ranges | | Existing presentation | Derivation or design-led workflows | Removing stale slides and checking the source file | | Images and media | Visual evidence or assets | Using relevant, legible, appropriately licensed files | ## Brief + evidence works better than either alone Diagram showing a brief and evidence combining into generation input, then producing a focused outline ## Improve source quality * Include only material relevant to the presentation goal. * State which facts, quotes, dates, and figures must remain exact. * Define acronyms and explain internal terminology. * Make units and reporting periods explicit in structured data. * Separate instructions from source content when possible. * Avoid conflicting versions of the same document unless you explain which one should win. Uploaded or pasted material does not become automatically correct because it appears in a generated slide. Compare important output with the original source before delivery. ## Understand where content is processed Cloud processes content through the managed service. In self-hosted deployments, the application runs on your infrastructure, but configured external providers may still receive prompts or derived content. Review your provider configuration and data-handling requirements before using sensitive material. Learn how documents, structured data, images, and charts enter the workflow.
