Claude can hold 200,000 tokens in a single conversation — roughly 500 pages of text. This makes it the best AI for document analysis: upload a 50-page report, ask questions about it, and get answers that reference specific sections. Here's exactly how I do it, including the prompts I use.

Why Is Claude Better Than ChatGPT for Documents?

Context window size. ChatGPT's 128K tokens is generous but Claude's 200K tokens handles longer documents more reliably. More importantly, Claude tends to quote and reference specific passages rather than summarize broadly — which matters when you're analyzing contracts, reports, or research papers where precision matters.

Key Takeaway

For documents under 30 pages, ChatGPT and Claude are both fine. For anything longer, Claude's larger context window and more precise referencing make it the better choice.

What's the Step-by-Step Workflow?

1
Upload and orient
Upload the PDF to Claude. First prompt: "I've uploaded [document name]. Read the entire document and give me a 5-bullet summary of the main points." This confirms Claude has ingested it correctly and gives you an overview.
2
Ask specific extraction questions
"What financial projections are mentioned? List each with the page or section where it appears." or "What are the three strongest arguments the author makes? Quote the relevant passages." Specificity gets you usable answers.
3
Challenge and cross-reference
"Does the data in section 3 support the conclusions in section 7?" or "Are there any contradictions between the executive summary and the detailed findings?" This is where AI analysis gets genuinely valuable.
4
Generate your deliverable
"Based on this document, write a 200-word executive briefing for my VP who doesn't have time to read the full report. Focus on the three decisions that need to be made." This turns raw analysis into something you can send immediately.
Pro tip

Always ask Claude to quote specific passages rather than paraphrase. Say "Quote the exact text that supports this claim." This makes it easy to verify the AI's interpretation against the source — and gives you citable evidence for your own work.
