Use **Design Studio** to convert a filled PowerPoint presentation into a reusable custom design for Smart mode. Presenton analyzes the source slides, resolves their fonts, and generates a design that Smart presentations can use with flexible content. Design creation is a Presenton Cloud Smart-mode workflow. For fixed Standard layouts, use [Template creation](/user-guide/template-creation). ## Designs and templates | Reusable asset | Presentation mode | Best for | | -------------- | ----------------- | ------------------------------------------------------------------------------ | | Design | Smart | Flexible slide composition based on the source presentation's visual direction | | Template | Standard | Predictable layouts converted from individual source slides | Upload a filled PPTX with representative content and a consistent visual system. An empty master or slides made only from placeholders do not give Design Studio enough information to analyze the design reliably. ## Create a custom design Start a new presentation. Open the mode selector and choose **Smart**.

## Verify a new design * Generate a short presentation with varied slide purposes. * Check that the visual direction remains consistent across slides. * Confirm all intended fonts render correctly. * Review both short and long content for overflow or weak spacing. * Export PPTX and PDF and inspect both files before using the design for repeated work. Use Template Studio when you need fixed, reusable layouts for Standard presentations. Continue with Canvas editing or the AI assistant after generating with the design.
