reading a dense strategy document
The Problem
The modern workplace involves an extraordinary amount of reading. Strategy documents, supplier proposals, legal contracts, research reports, board packs. Most of these documents are long, dense, and written for thoroughness rather than readability. Getting to the information you actually need often means working through pages of context you don't.
Claude Cowork eliminates this bottleneck. Upload or paste a document, tell Claude what you need from it — executive summary, key decisions, action items, specific section — and it returns exactly that in seconds. A 50-page report becomes a structured summary you can read in two minutes. A complex contract yields its key obligations in a table. A supplier proposal is distilled to the three things that actually matter for your decision.
This is particularly valuable when you're dealing with information overload: multiple proposals to compare, a backlog of industry reports, meeting prep for a document-heavy session. Claude doesn't replace reading when reading matters — but it means you can read deeply where it counts and get the gist efficiently everywhere else.
What Claude Does Here
- Produces executive summaries from lengthy reports and documents
- Extracts key decisions, actions, and deadlines from meeting materials
- Highlights the most important sections so you know where to focus
- Compares two or more documents side-by-side
- Answers specific questions about a document without requiring a full read
- Adapts summary depth — one paragraph, one page, or bullet points — to your need
How to Set It Up
1
Upload or paste the document
Paste text directly into Claude, or upload a file. For long documents, you can provide the full text. Claude can handle substantial document lengths — far more than a typical business report.
2
Tell Claude your role and context
The best summaries happen when Claude knows who you are and why you need the summary. "Summarise this for a non-technical managing director who needs to decide whether to proceed" produces different output to "Summarise this for a project manager who needs action items." Context matters.
3
Specify the summary type and length
Choose the format that fits your use: a three-sentence executive summary, a structured breakdown of key sections, a table of decisions and owners, a list of action items with deadlines, or a comparative analysis if you're evaluating multiple documents.
4
Ask follow-up questions
Once Claude has summarised the document, you can ask specific follow-up questions without re-reading the source. "What are the contract's payment terms?" "What risks does the report flag?" "What decision is the board being asked to make?" Claude has the full context and answers in seconds.
5
Build a summary prompt for your common document types
If you regularly read the same type of document — supplier proposals, board reports, research papers — create a saved prompt tailored to that format. This means every time you receive a new one, you get an instant summary without any additional setup.
Example Prompt
Prompt

I need:
1. A 3-sentence executive summary
2. What the supplier is proposing to do, and the key costs
3. Any risks or dependencies mentioned
4. My recommended next steps based on the document

What Claude Returns
Claude's Output
Executive Summary
Apex Logistics Software is proposing a 12-month contract to migrate our warehouse management system to their cloud platform at a total cost of £38,400. The proposal outlines a phased implementation beginning in March, with full go-live by June. Key dependencies include a data audit in February and availability of three internal IT staff members during the migration period.
What They're Proposing
Migration of existing WMS data to Apex Cloud platform. 6-week implementation timeline with two phases. Training for 24 staff members. 12-month support contract post go-live. Annual licence fee of £18,000 after Year 1.
Costs
Setup and migration: £20,400 (one-off), Annual licence: £18,000/year
Risks & Dependencies
- Requires 3 internal IT staff for 6 weeks during migration — capacity risk in March
- Data audit must be completed by 7 February (tight deadline)
- No SLA penalties mentioned for missed go-live dates
- Legacy data migration from 2018–2020 flagged as potentially complex
Recommended Next Steps
1. Confirm IT team availability for March before signing
2. Request SLA clause additions around go-live guarantee
3. Schedule data audit for w/c 27 January to meet the February deadline
Frequently Asked Questions
Can Claude summarise PDFs?
Yes. You can upload PDF files directly to Claude and it will read the content. For very large PDFs (100+ pages), pasting the most relevant sections while asking Claude to focus on specific areas can improve efficiency and precision.
How long a document can Claude handle?
Claude has a large context window that can hold tens of thousands of words — far more than most business documents. Typical reports, contracts, proposals, and board packs are well within this limit. For extremely long documents (book-length), breaking them into sections and summarising each works well.
Will Claude miss important details in the summary?
Claude is comprehensive, but no summary can capture everything. The risk of missing something is reduced by being specific about what you need in your prompt. If there's a section or topic you know matters, ask explicitly: "Focus particularly on the liability clauses" or "Make sure you capture all the deadlines."
Can I ask questions about the document after Claude summarises it?
Yes — Claude retains the full document context within the conversation. After receiving a summary, you can ask follow-up questions as naturally as you'd ask a colleague who'd read the document. "What's the payment schedule?" "Does it mention data ownership?" "What's the exit clause?"
Is this useful for comparing multiple documents?
Absolutely. Paste two or more documents and ask Claude to compare them on specific criteria — pricing, scope, risk, timeline. This is particularly useful for procurement decisions, where you might be comparing multiple supplier proposals against a consistent set of evaluation criteria.
