# Your First Chat

## Chat with a single file

1. Go to the **Library** tab
2. Click on any file to open it
3. Type a question in the chat input at the bottom
4. Hit Enter or click the send button

Knowbase will return an answer with **source citations** — clickable references that take you to the exact section of the document.

## Chat with your entire library

1. Go to the **Chat** tab in the top navigation
2. Type any question — Knowbase searches across **all your files** at once
3. The answer will include citations from whichever files are most relevant

{% hint style="info" %}
**Tip:** You can also drop specific files into the chat to narrow the search to just those documents.
{% endhint %}

## Follow-up questions

Knowbase remembers the conversation context. Ask follow-up questions naturally — no need to repeat yourself.
