# Chat with a File

## How it works

1. Go to the **Library** and click on any file
2. The file opens with a chat panel on the right
3. Type your question and press Enter
4. Knowbase searches the file and returns an answer with **source citations**

## Source citations

Every answer includes numbered citations like **\[1]**, **\[2]**. Click a citation to jump to the exact section of the document where the answer was found.

* **PDFs** — jumps to the page and highlights the text
* **Videos/Audio** — seeks to the timestamp
* **YouTube** — jumps to the moment in the video

## Follow-up questions

The conversation remembers context. You can ask follow-ups without repeating yourself:

> **You:** What are the key findings? **Knowbase:** The study found three main results... \[1]\[2] **You:** Tell me more about the second one.

## Tips

* Be specific — "What was the Q3 revenue?" works better than "Tell me about the finances"
* Use Thinking Mode for questions that require reasoning across multiple sections
