Use a document when the presentation must follow existing facts or a known narrative. The most reliable workflow combines a focused source with a short instruction explaining what the audience needs from it.

​
Supported source files

The visible source-file list differs between the live Cloud and open-source screens. Always follow the list shown by the product you are using.
The current Cloud Generate screen advertises these extensions:.pdf, .txt, .md, .pptx, .ppt, .docx, .doc, .csv, .xlsx, .xls, .html, .htm, .adoc, and .asciidoc.Generate page with the prompt, presentation controls, attachment area, and supported source-file formats
Attach documents and review supported source formats

​
Prepare the source

  • Use one authoritative file for the first attempt.
  • Remove unrelated appendices, duplicate versions, and hidden spreadsheet sheets.
  • Note the names, dates, figures, and conclusions that must remain exact.
  • Prefer selectable text. Scanned PDFs and images depend on OCR quality.
  • Use clear headings and labels so extracted sections retain their meaning.

​
Generate from a document

Cloud and open-source use the same document-to-presentation sequence, with product-specific source lists and provider behavior.
1

Open Generate

Start a new presentation and open the Generate page.
2

Attach the source

Select Attachments (optional) or drop one or more files accepted by the active product into the upload area. Wait until each filename appears, then choose an explicit output language. You can clear all attachments or remove an individual file before continuing.Generate page with an attached source document
A source document ready to process
3

Explain how to use it

Add a prompt that names the audience, desired outcome, priority sections, and facts that must be preserved.
4

Process the source

Set the remaining controls and select Get Started. Presenton uploads and decomposes the files, then requests outline generation. Large or scanned sources can take longer.
5

Review the outline against the source

Correct omissions, unsupported claims, and sequencing before choosing the presentation design.Presentation outline generated from an uploaded document

Generate and verify

Compare the finished slides with the source, then export and inspect the result.
Open-source document parsing, OCR, supported file behavior, and limits depend on the services configured by the deployment administrator. When files are attached, the current browser flow requires an explicit language instead of Auto. Cloud account limits can also change independently of the visible file-extension list.
Verify every important number, date, name, chart, table, and claim against the original file. Document grounding reduces guesswork but does not replace review.

Generation workflow

Follow the complete prompt, attachment, outline, and generation workflow.
