Ever opened a 50-page report or a dense slide deck and thought: “How can I get the key points without reading it all?”
With le Chat, you can upload files and ask it to analyze them directly.
Here are the most common ways to use this feature.
Main examples
Summarize a PDF
A frequent use case is to summarize long documents and then ask follow-up questions.
📌 For example, you might want to summarize a technical document with a focus on security, or review a company’s annual report from a financial perspective.
For instance, let’s work with the IPCC climate report.
Click the
+button in the chat interface.Select the PDF from your computer.
Ask your question, for example:
What specific impacts can we expect from global warming between now and 2050?
Uploading a PDF file to le Chat
Le Chat analyzes the PDF and answers the question
The answer isn’t just based on general knowledge. Le Chat draws its information directly from the document you uploaded.
📌 You can upload many types of files, not just PDFs. Le Chat currently supports formats such as:
PDF (.pdf)
Word (.docx)
PowerPoint (.pptx)
CSV (.csv)
Text (.txt)
Markdown (.md)
Excel (.xlsx)
Code files (specifically but not limited to .html .css .js .php or .py)
🙋 Quick question: Do you use my uploaded documents for training your models?

Depending on your plan, uploaded data may be included in training, but you can opt out at any time.
Analyze a URL
Instead of uploading a file, you can also analyze a remote file (and even a webpage!) by pasting its URL into the chat.
🔑 Make sure the Web search tool is enabled, as explained in the previous section.
Paste the link to the IPCC report in your question, and le Chat will fetch the content and answer.
You’ll see a “link” icon and an Opened Page mention in the response.

Describing visuals: “Describe the diagram in this image”
Analyzing screenshots: “What’s happening in this screenshot?”
