# File Uploads

> Upload documents and ask Atlas questions about them

Atlas can analyze documents you upload. This is useful when you have a specific document — a conference background guide, a policy paper, a treaty text — and you want to ask targeted questions about it.

## Supported file types

* **PDF** — the most common use case
* **Word documents** (.docx)
* **Plain text** (.txt)

File size limit: 25 MB per file. You can upload multiple files in a single search.

## How to upload a file

1. Go to Search and click the **paperclip icon** (or the attachment button) in the search bar
2. Select your file(s)
3. Type your question about the document
4. Submit

Atlas will read the document and answer your question based on its contents, citing specific sections where relevant.

## What to use file uploads for

<AccordionGroup>
  <Accordion title="Conference background guide analysis" icon="landmark">
    Most MUN conferences publish a background guide (study guide) for each committee. Upload it and ask:

    * "What are the three main issues covered in this background guide?"
    * "What does this guide say about my country's position?"
    * "What are the key facts I need to know from this document?"
    * "Summarize this background guide in bullet points"
  </Accordion>

  <Accordion title="Resolution and treaty analysis" icon="file-contract">
    Upload a UN resolution or treaty text and ask Atlas to explain it:

    * "What does operative clause 5 of this resolution require countries to do?"
    * "What are the enforcement mechanisms in this treaty?"
    * "Which countries are obligated under this resolution and which are not?"
  </Accordion>

  <Accordion title="Position paper review" icon="file-pen">
    Upload a draft position paper and ask Atlas for feedback:

    * "Is this position paper arguing consistently?"
    * "What key arguments am I missing for this country's position?"
    * "Does this position paper follow standard MUN format?"
  </Accordion>

  <Accordion title="News article or report analysis" icon="newspaper">
    Upload a report or article and extract the key information:

    * "What are the three most important findings in this report?"
    * "Who does this report say is responsible for the conflict?"
    * "What recommendations does this policy paper make?"
  </Accordion>
</AccordionGroup>

## Combining file uploads with web search

When you upload a file and ask a question, Atlas uses both the document *and* its web knowledge to answer. This means it can:

* Ground the document's claims in broader context
* Add citations from external sources alongside citations from your document
* Compare what the document says with what other sources say

If you want Atlas to focus *only* on your uploaded document (not the web), specify that in your question: "Based only on this document, what does it say about X?"

<Tip>
  For best results with large PDFs, ask specific questions rather than "summarize everything." A 200-page background guide is better tackled with targeted questions like "What does this document say about \[specific issue]?"
