How to Use a ChatPDF Tool | Step-by-Step Guide
The thought of reading through a long PDF and trying to make sense of it can be daunting. Thankfully there’s a solution.
Tools like QuillBot’s AI ChatPDF allow you to upload one or more PDFs and “chat” with them—you can ask questions, break down complex sections, or get a clear summary of the key takeaways.
Read on to learn what ChatPDF tools are and how they can help you decipher complicated academic papers or dense technical documents with ease.
What are ChatPDF tools?
ChatPDF tools are AI-powered assistants designed to help you interact with PDF documents in an intuitive way. Instead of scrolling through dozens of pages to find the answers you’re looking for, you can upload your file and simply ask questions, as if you were talking to an expert.
These tools analyze your document and use natural language processing to provide their answers (like ChatGPT, but tailored to your PDF). This lets you do things like request a summary, clarify technical jargon, or pull out specific details, all without combing through the whole document yourself.
How to use ChatPDF
ChatPDF tools are fast and easy to use. Open the tool, upload your file(s), and start asking questions. Below is an example of how to use QuillBot’s AI ChatPDF tool.
1. Upload your document
On the tool’s homepage, you’ll see a dialog box with an “Upload PDF” button. Click on this to select a PDF from your computer and select “Upload.”
The homepage of the tool—click “Upload PDF” to add your file.

Once your PDF has been uploaded, you’ll see it appear in the text box. At this point you can either upload more documents or start asking questions!

2. Ask your first question
Now that you’ve uploaded your first document, you’re ready to start asking questions. Click on the text field that says “Ask me anything” and ask away!
If you aren’t sure what your first question should be, a good place to start is to think about your goal: why do you need to read this document? Your first question should get you closer to this purpose.
Here are some strong first questions to try:
- Summarize this document in five clear bullet points
- What is this PDF about?
- What are the main sections of this document?
- Which part of this document should I read if I only have five minutes?
- What recommendations does this report make?
- Explain this article as if I’m a beginner in this field

Once you’ve entered your question, press the green arrow to start chatting.
3. Go deeper
Pressing the green arrow will bring you to a chat window where you can keep the conversation going. A great feature of ChatPDF tools is that they are, by definition, a chat. Use this tool as if you were talking to an expert teacher or colleague.
You can refine your first question, ask for a different answer format, or ask for more and more specific details. If something doesn’t make sense, ask for a more detailed explanation or explain what you find unclear, and the tool will help you.
