# Overview

<Tip>
  Select the material you want flashcards on, with full control over what gets
  imported. This will then get converted to a simple text format that both
  you, and the flashcard AI, can view.

## How Janus Handles Uploads

<Steps>
  <Step title="Convert">
    Janus supports a wide variety of media, from audio to complex documents like PDFs. The converter will extract text and transcripts from the upload and standardize it into markdown.
  </Step>

  <Step title="Annotate">
    Some input integrations (e.g. [Readwise](/workflow/upload/integrations/readwise)) provide additional highlights. When possible, we match these with the converted text so that your document can be pre-populated with highlights.
  </Step>

  <Step title="Save">
    This processed document is then saved and associated with a **notebook**. Notebooks are only visible to you and Janus.
  </Step>

  <Step title="Bill">
    Some conversion requires using external vendors services and we currently forward on the costs to you. Check out the integration pages for details on costs.
