Common mistake

Uploading an entire 100-page document and asking "summarize this." You get a vague overview that misses what matters to you. Instead, tell the AI what you care about: "Summarize this focusing on budget implications and timeline changes." Specific instructions get specific summaries.

Before you start

The document you want summarized — PDF, text, or pasted content

Exact action

1. Go to claude.ai and sign in (or create a free account) 2. Click the "+" button to start a new conversation 3. If your document is a PDF: click the paperclip icon at the bottom of the chat, select your file, and wait for it to upload 4. If your document is text: copy the full text and paste it directly into the message box 5. For web articles: copy the URL or the article text — Claude can read pasted content but not live URLs on the free tier

You see the file name appear as an attachment in the chat, or your pasted text shows up in the message box. Claude may show a brief loading indicator while processing the file.

If the file won't upload, check that it's a PDF under 10MB. If you see "file type not supported," convert your document to PDF first using Google Docs or a free online converter. For very long documents, try splitting them into sections.

Ask for a targeted summary with specific focus areas

Tell Claude exactly what kind of summary you need

Exact action

1. In the same conversation where you uploaded your document, type your summary request 2. Be specific about what you want. Instead of "summarize this," try: - "Summarize this report in 5 bullet points, focusing on budget changes and deadlines" - "Give me a 3-paragraph summary highlighting the key recommendations" - "List the top 10 takeaways from this document, ranked by importance" 3. If the document is for a specific audience, mention that: "Summarize this for my team who hasn't read it" 4. Press Enter to send your request 5. Wait for Claude to generate the summary (usually 10–30 seconds)

Claude returns a well-organized summary that directly addresses your focus areas. The summary should have clear structure — bullet points, numbered lists, or distinct paragraphs — and reference specific details from the document rather than generic statements.

If the summary is too vague or generic, you were probably too broad in your request. Reply with: "This is too high-level. Please include specific numbers, names, and dates from the document." If Claude says it can't access the document, re-upload it in the same conversation.

Follow up for details on sections that matter most

Drill into specific sections or ask follow-up questions

Exact action

1. Review the summary Claude gave you and identify areas where you need more detail 2. Ask targeted follow-up questions like: - "Expand on point 3 — what exactly are the timeline changes?" - "What action items does this document suggest?" - "Are there any risks or concerns mentioned that didn't make the summary?" 3. Ask Claude to reformat if needed: "Turn this summary into an email I can send to my manager" or "Create a bullet-point action list from this" 4. Copy the final summary by clicking the copy icon on Claude's response 5. Paste it into your notes app, email, or document

You have a detailed, accurate summary plus any follow-up information you requested. The summary should match the key points when you spot-check it against the original document. You have it saved somewhere useful — your notes, an email draft, or a shared document.

If Claude's follow-up answers contradict the original summary, it may be hallucinating details. Cross-check important facts against the original document. Ask Claude to "quote the exact passage" if you need to verify a specific claim.

All done!
