What does this setup do?
Upload a pile of documents, like proposals, reports or contracts, and get one short brief with each point tied to its source and every conflict between documents called out.
Who is it for?
Anyone who has to read ten documents to make one decision or write one summary for a boss, client or board.
How do you set it up?
Tools
- Claude or ChatGPT with file upload
- The documents, as PDF, Word or text
Steps
- Collect the documents and give each a clear file name, like vendor-a-proposal.pdf.
- Upload them to one chat, or to a project if you will come back to them. Anthropic says files can go in a chat or in a project's Files section.
- Paste the prompt below and say what the brief is for, such as choosing a vendor.
- Read the conflicts section first. That is where the decision usually is.
- Check every number in the brief against the file it cites.
- Ask for a second version in the format you need, such as one page for your boss or a table.
Example output
Illustrative. Your results will differ.
- Answer: Vendor B fits the budget; Vendor A is faster.
- vendor-a-proposal.pdf: $12,400, 3 weeks, includes training
- vendor-b-proposal.pdf: $9,800, 5 weeks, training extra
- Conflict: support hours (A: 24/7, B: weekdays only)
- Missing: B's training price
Where to paste this prompt

Copy-paste prompt
Adapt bracketed fields to your situation.
I uploaded [NUMBER] documents. Write one brief for this purpose: [E.G. CHOOSE A VENDOR, BRIEF MY BOSS].
Format:
1. One paragraph: the answer to my purpose, if the documents support one.
2. Each document in 2 to 3 bullet points, labeled with its file name.
3. Where documents agree.
4. Where they conflict, quoting each side with its file name.
5. What is missing that I would need to decide.
Rules: keep numbers and dates exactly as written, cite the file name for every point, and say Not stated rather than guessing.Newsletter

What usually goes wrong?
Where agents tend to stall on this job. More patterns in Where AI gets stuck.
- A scanned PDF with no text layer reads as empty. Ask it to list any file it could not read.
- Numbers drift between the documents and the brief. Check each one.
- Asking for a recommendation before reading the conflicts.
Which chat tools work with this prompt?
Paste the prompt into any of these assistants (free or paid tiers).
- Claude
- ChatGPT
Common questions
- Can AI summarize several documents at once?
- Yes. Upload them together and ask for a brief that cites the file for each point and lists where they conflict.
- How do I avoid wrong numbers?
- Require exact numbers with file names, then check each against its source.
- What if a file will not read?
- Ask the AI to list any file it could not read. Scanned PDFs may need text recognition first.
What tips make it smoother?
- Clear file names make the citations useful.
- Ask for conflicts as quotes; summaries of conflicts tend to smooth them over.
- If documents are long, ask for the brief in two passes: first per document, then combined.
