## PDF Processing

### Reading and Analysis

After uploading a PDF file, Expert can:

* Extract the full text and answer related questions
* Recognize text in scanned documents via OCR
* Summarize key points and compare multiple documents
* Extract data from tables and charts

### Creation and Layout

<AccordionGroup>
  <Accordion title="Standard PDF Generation">
    Tell Expert what content you need in a PDF, and it will generate a well-structured document. Ideal for reports, contracts, manuals, and other standard documents.
  </Accordion>

  <Accordion title="Kami Premium Layout">
    When you need high-quality typesetting, Expert uses the Kami layout engine to produce magazine-grade PDFs — with precise control over fonts, paragraphs, text-image flow, headers, footers, and more. Perfect for brochures, proposals, portfolios, and other visually demanding materials.
  </Accordion>
</AccordionGroup>

### Other Operations

  <Step title="Edit an Existing Document">
    Upload a .docx file and tell Expert what changes to make — adjust formatting, modify content, add sections, etc.
  </Step>

  <Step title="Download the Result">
    Once processing is complete, Expert returns a downloadable .docx file that you can open and edit in Word or WPS.
  </Step>
</Steps>

## PowerPoint / PPTX Processing

Expert offers two ways to create presentations:

<AccordionGroup>
  <Accordion title="Native PPTX">
    Generate standard .pptx files that can be opened and edited directly in PowerPoint or Keynote. Supports multi-slide layouts, title slides, bullet-point lists, embedded charts, and more. Ideal for formal scenarios where further editing or meeting presentations are needed.
  </Accordion>

  <Accordion title="HTML Deck Web Presentation">
    Generate HTML-based web presentations. Richer visual effects — supports animated transitions, interactive elements, and custom layouts. Ideal for online sharing or presentations with higher visual standards. Once generated, it can be played in full-screen directly in a browser.
  </Accordion>
</AccordionGroup>

### Recommendations

* Clearly state the **audience** and **context** of the presentation (e.g., "a fundraising pitch for investors"), and Expert will adjust the content depth and visual style accordingly
* Provide an outline or key points, and Expert will expand them into complete slides
* If you have brand colors or style preferences, let Expert know in advance

## General Tips

<Tip>
  * When uploading existing documents, Expert will first understand the document's content, allowing you to make further processing requests based on that understanding
  * You can process multiple documents in a single conversation — for example, "Merge these three reports into one PDF"
  * All generated documents are directly downloadable and compatible with mainstream office software
</Tip>

<Warning>
  Processing large documents (PDFs over 100 pages or DOCX files with many images) may take longer. When necessary, consider splitting them into smaller files before uploading.
</Warning>

## Billing

Credit consumption for document processing primarily comes from model token usage in the conversation. Document generation and download themselves incur no additional charges.
