Share a Document with Claude

You'll want a working sense of Graduate to Chat before this lesson, since document sharing is a chat workflow and knowing when to use chat over tab-complete is the prerequisite skill.

You have a 14-page contract sitting on your desk and you need to find the renewal clause before your 2pm call. You could read the whole thing, or you could drop it into Claude and ask the exact question you need answered. Claude can read a 60-page PDF in seconds. What saves you time is asking the right question, not the upload itself.

Here is the before and after: Uploading a file and asking 'summarize this' gets you a summary. That is fine if you need an overview. But if you need a specific answer, ask a specific question: 'What are the renewal terms and the notice period in this contract?' or 'Does this document mention any penalty clauses?' The more specific the question, the more useful the answer.

You can share files in three ways depending on which tool you use. In Claude.ai on desktop, there is a paperclip icon in the chat input. Click it to attach a PDF, Word doc, or text file. In Claude Desktop (the Mac or Windows app), you can drag and drop files directly into the chat window. Google Docs and other web documents work best when you copy the text and paste it directly into the chat, since Claude cannot access links that require you to log in.

One file, one focused question. That is the pattern that gets useful answers on the first try.

Paste this into Claude:

I am uploading [describe your file: e.g. 'a 14-page vendor contract', 'a 6-page research report', 'a meeting transcript from last Tuesday']. Here is the specific thing I need to find or understand: [your focused question, e.g. 'What is the renewal period and how much notice do I need to give to cancel?' or 'What were the three main action items from this meeting?']. Please answer that specific question first, then tell me if there is anything else in the document I should pay attention to related to this topic.

What good looks like:

• You attached or pasted a real document you actually need to work with
• You asked one specific question rather than just 'summarize this'
• Claude's answer addressed your actual question with specific details from the document
• You got a usable answer without reading the whole document yourself
• You followed up with at least one more specific question based on the first answer

What a good response looks like:

Based on the vendor contract you uploaded, here are the renewal terms:

The contract auto-renews for successive 12-month periods unless either party gives written notice at least 60 days before the end of the current term. The current term ends on December 31, 2025, which means you would need to send a cancellation notice by November 1, 2025 to avoid being locked into another year.

One thing worth flagging: Section 8.3 includes a price adjustment clause that allows the vendor to increase fees by up to 8% at each renewal without renegotiation. If you are planning to renew, you may want to address that cap before the November deadline.

Would you like me to pull the exact language from those two sections so you can share it with your legal team?

Paste this into Claude:

I have uploaded [describe your file]. I want to use Claude as a thinking partner on this document, not just a reader. After you read it, I want you to: (1) Answer this specific question: [your question]. (2) Tell me what I should be asking that I have not asked yet. (3) Flag any section that seems unusual, risky, or worth a second look, even if I did not ask about it. Give me your honest read, not just a summary.

What good looks like:

• Claude answered your specific question with details from the document
• Claude flagged at least one thing you had not thought to ask about
• You found at least one section of the document worth reviewing that you had not noticed before
• You used Claude's flag as a starting point for a follow-up question

What a good response looks like:

Your specific question answered: The indemnification clause in Section 11 puts the liability on your company, not the vendor, for any third-party claims arising from your use of their service. That is the opposite of what a standard indemnification clause looks like.

Questions you have not asked yet that are worth answering: What happens to your data if the vendor goes out of business or you cancel? Section 14 (Data Retention) says they delete everything within 30 days. If your team has been using this service to store client documents, you need a data export before you cancel, not after.

Section flagged for a second look: Section 6.2 (Acceptable Use) prohibits using the service 'for competitive analysis.' That language is broad and could technically cover benchmarking you do routinely. I would confirm with your legal team whether your current use falls inside that boundary.
