How to Use Claude AI for Work: 10 Practical Examples
How to Use Claude AI for Work: 10 Practical Examples
Claude is one of those tools that either clicks immediately or leaves you wondering what all the fuss is about. The difference usually comes down to whether you’re using it for the right tasks — and whether your prompts are specific enough to get something genuinely useful back. If you want to explore other options alongside Claude, here are the best Claude AI alternatives in 2026.
This guide focuses entirely on practical, work-specific use cases. No fluff, no vague suggestions. You’ll see 10 concrete examples with the kinds of prompts that actually work, what to expect from Claude’s output, and how to get the most out of the Projects feature for ongoing work.
Prerequisites — What You Need Before Starting
- A Claude account at claude.ai — free to sign up, no credit card required
- The free plan gives you basic access to Claude Sonnet with limited usage. For serious work use, Claude Pro ($20/month) gives you 5x more usage, access to Claude’s full model capabilities, file uploads, and extended reasoning.
- For the Projects feature and heavier document analysis, Pro is essentially required.
Claude runs in your browser and has desktop apps for Mac and Windows. There’s also a mobile app for iOS and Android if you need it on the go.
Step 1: Getting Oriented — The Claude Interface
When you open claude.ai, you see a simple chat interface. Type a message, press Enter, and Claude responds. That’s the whole interface at the basic level.
A few things worth knowing before you dive into specific use cases:
The context window is large. Claude can handle very long conversations and large documents. You can paste in thousands of words of text and Claude will read all of it. This is one of its biggest advantages for work tasks.
Claude is direct about uncertainty. Unlike some AI tools, Claude will tell you when it’s not sure about something rather than confidently making things up. Pay attention to hedging language — it usually means you should verify the claim.
Specificity matters enormously. A vague prompt gets a generic response. A detailed, specific prompt gets output you can actually use. Every example in this guide includes the kind of specific prompt that produces useful results.
You can give Claude a role. Starting your message with “Act as a senior marketing strategist” or “You are an experienced software engineer” shifts the tone, depth, and assumptions in Claude’s response in ways that can be very useful.
Step 2: Setting Up Projects for Ongoing Work
Before getting into individual use cases, let’s cover Projects — Claude’s feature for maintaining context across multiple conversations.
What Projects are
A Project is a dedicated workspace where you can upload files, set standing instructions, and have multiple separate conversations that all share the same knowledge base. Think of it as Claude with memory about your specific work context.
How to create a Project
– “You are helping me manage marketing for a B2B SaaS company with 50 employees. Our main product is a project management tool targeting construction firms. Always use a professional but direct tone.”
Why Projects matter for work
Without Projects, every Claude conversation starts from zero. You have to re-explain your company, your context, your preferences every time. With a Project set up correctly, Claude already knows your situation the moment you start a new conversation.
This makes Claude dramatically more useful for recurring work tasks. Instead of spending the first 200 words of every conversation re-establishing context, you just ask the question.
10 Practical Work Examples
Example 1: Summarizing a Long Document
The task: You have a 40-page industry report, a lengthy legal document, or a dense research paper. You need the key points without reading the whole thing.
How to do it:
Prompt:
“Here is [document name]. Please give me:
1. A 3-sentence executive summary
2. The 5 most important findings or points
3. Any recommendations or action items mentioned
4. Any data or statistics I should know about
> [paste document]”
What to expect: Claude reads the full document and extracts exactly what you asked for. For a 40-page report, this takes about 20 seconds and saves you 45 minutes of reading.
Pro tip: If you need to go deeper on a specific section, follow up with “Tell me more about the section on [topic]” — Claude remembers the full document from the context and can drill down without you re-pasting anything.
Example 2: Drafting Professional Emails
The task: Writing emails that are clear, professional, and appropriately toned — without agonizing over every sentence.
The prompt structure that works:
“Write a professional email with the following details:
– To: [recipient role/relationship]
– Purpose: [what the email needs to accomplish]
– Key points to include: [list them]
– Tone: [formal/friendly/firm/apologetic]
– Length: [short and direct / one page / brief with a clear CTA]”
Real example:
“Write a professional email with the following details:
– To: A client who has missed two payment deadlines on a $4,500 invoice
– Purpose: To firmly but professionally request payment without damaging the relationship
– Key points to include: The invoice number is #2024-089, it’s now 45 days overdue, we value the working relationship, we need payment within 7 business days, we’re happy to discuss payment plans if there’s an issue
– Tone: Firm but not aggressive, professional
– Length: Short and direct”
Claude will produce an email that’s ready to send with minor edits for your specific name and details. For variations, follow up with “Make it slightly more formal” or “Add a line offering to hop on a call.”
Example 3: Editing and Improving Your Writing
The task: You have a draft — a report, a proposal, a newsletter, a LinkedIn post — and it needs to be better without losing your voice.
The approach:
Paste your draft and give Claude a specific editing brief. Vague instructions like “improve this” produce generic edits. Specific briefs produce focused improvements.
Prompt:
“Please edit the following draft with these specific goals:
– Cut it by roughly 20% without losing key information
– Replace any jargon with plain language
– Make sure the opening paragraph immediately states the main point (right now it buries the lede)
– Flag any sentences that are unclear or could be misread
– Keep my voice — don’t make it sound like a generic corporate document
> Here’s the draft:
[paste your text]”
Claude will return the revised text and can explain specific changes it made if you ask. For long documents, you can work section by section.
Also useful for writing:
- “Write 3 variations of this headline” (paste your current one)
- “Rewrite this paragraph so it’s more concise”
- “Check this for inconsistencies in tone”
- “Does this proposal have a clear call to action? If not, suggest where to add one.”
Example 4: Analyzing Data Without a Spreadsheet Tool
The task: You have a table of data — sales numbers, survey results, performance metrics — and you need to understand it quickly without digging into Excel formulas.
How it works:
Paste your data (as a table, CSV text, or even a rough list) and tell Claude what you want to understand.
Prompt:
“Here is our sales data by region for Q4. Please:
1. Identify which region performed best and worst relative to their Q3 numbers
2. Calculate the total revenue and average deal size across all regions
3. Flag any anomalies or patterns that stand out
4. Give me 2-3 hypotheses for why the Northeast region declined
> [paste data]”
For survey data:
“I have results from a customer satisfaction survey. Here are the open-ended responses. Please:
1. Identify the 5 most common themes or complaints
2. Estimate what percentage of responses fall into each theme
3. Flag the most positive and most negative responses specifically
4. Summarize what customers are saying in 3 sentences
> [paste responses]”
Claude doesn’t run calculations as reliably as Excel for complex math, but for pattern recognition, summarization, and drawing conclusions from data, it’s remarkably effective and much faster than doing it manually.
Example 5: Writing and Debugging Code
The task: You need to write a script, fix a bug, or understand code you didn’t write.
Claude is exceptionally good at coding tasks and handles a very wide range of languages — Python, JavaScript, SQL, TypeScript, HTML/CSS, Bash, and many more.
For writing new code:
“Write a Python script that:
– Reads a CSV file called ‘sales_data.csv’
– Filters rows where the ‘region’ column equals ‘Northeast’
– Calculates the total revenue from the ‘amount’ column for those rows
– Outputs the total to the console and saves the filtered rows to a new file called ‘northeast_sales.csv’
> Include comments explaining what each section does.”
Claude writes the full script with comments. If it doesn’t run correctly, paste the error message back in: “I got this error when I ran the script: [error text]. What’s wrong and how do I fix it?”
For understanding unfamiliar code:
“Here is a function from our codebase that I didn’t write. Please:
1. Explain what it does in plain English
2. Walk me through it line by line
3. Note any potential bugs or edge cases I should be aware of
> [paste code]”
For SQL specifically:
“Write a SQL query that finds all customers who placed more than 3 orders in the last 90 days but whose most recent order was more than 30 days ago. The tables are: orders (order_id, customer_id, order_date, total_amount) and customers (customer_id, email, signup_date).”
Claude writes clean, readable SQL and explains what it’s doing.
Example 6: Preparing for Meetings and Interviews
The task: You have a client meeting, a job interview, a performance review, or a difficult conversation coming up and you want to be better prepared.
For client meetings:
“I have a discovery call with a potential client tomorrow. Here’s what I know about them:
– They run a 200-person logistics company
– They’re evaluating project management tools (our product)
– I found that their main pain point seems to be tracking subcontractor work
> Please help me:
1. Write 10 good discovery questions to ask them
2. Anticipate 3 objections they might have and give me responses
3. Suggest how to position our product relative to their specific logistics context
4. Write a one-paragraph intro that establishes credibility”
For job interviews:
“I have an interview for a Senior Marketing Manager role at a B2B software company. Here’s the job description: [paste JD]. Here’s my background: [brief summary of your experience].
> Please:
1. Identify the 5 skills or experiences they seem to value most
2. Suggest a relevant story from my background for each one
3. Write answers to these 3 likely interview questions in STAR format: ‘Tell me about a campaign you led from start to finish,’ ‘How do you handle data-driven decisions,’ and ‘How do you manage competing priorities?'”
Example 7: Competitive and Market Research Synthesis
The task: You’ve gathered research from various sources — competitor websites, industry reports, customer reviews — and you need to make sense of it all.
How it works:
Paste all your raw research into Claude and ask for synthesis. Claude’s long context window means it can handle large volumes of text and identify patterns across the whole thing.
Prompt:
“I’m going to paste in raw notes and excerpts from my competitive research on [market/product category]. Please analyze this and give me:
1. A comparison of how each competitor positions themselves (in a table if possible)
2. Gaps in the market that none of them seem to be addressing
3. The main messaging angles our competitors use
4. 3 strategic recommendations for how we could differentiate
> Here’s the research:
[paste your notes, excerpts, and data]”
This is much faster than trying to synthesize competitive research yourself, and Claude often surfaces patterns you might miss when reading sources individually.
Example 8: Creating Templates and Frameworks
The task: You need a repeatable template — for a process your team runs regularly, a document format, or a decision-making framework.
Claude is very good at structure, and creating templates is one of the things it does particularly well.
Examples that work:
“Create a template for a post-mortem document after a project failure. The template should help a team understand what went wrong, what went well, and what to do differently — without turning into a blame session. Include prompts or questions for each section.”
“Design a weekly team meeting agenda template for a 10-person product team. The meeting is 45 minutes. It should cover key metrics, blockers, and decisions needed — not status updates (we handle those async).”
“Create a framework for deciding whether to build or buy a software solution. Structure it as a series of questions with decision criteria. Our company is 80 people, Series A funded, with 3 engineers.”
Once Claude gives you a template, you can refine it: “Remove the ‘Lessons Learned’ section and instead add a section for tracking follow-up actions with owners and due dates.”
Example 9: Brainstorming and Problem-Solving
The task: You’re stuck on a problem and need a thinking partner who won’t get defensive or run out of ideas.
Claude is an effective brainstorming partner when you give it full context on the problem.
The setup:
“I’m trying to solve the following problem and I want to brainstorm solutions. Please don’t just validate my existing thinking — push back where you see issues and suggest approaches I might not have considered.
> Context: [describe your situation]
The problem: [state it clearly]
Constraints: [budget, time, team size, whatever applies]
What I’ve already tried or considered: [list them]
> Give me 8-10 different possible solutions, ranging from obvious to creative. Then tell me which 2-3 you’d prioritize and why.”
This framing — especially the “push back” instruction and the constraint to suggest things you haven’t already considered — produces more useful brainstorming than a standard “give me ideas” prompt.
Example 10: Document Analysis — Contracts, Legal Docs, and Reports
The task: You need to understand what a document says before you sign it, respond to it, or brief someone else on it — without paying for a lawyer to read every word.
Important disclaimer: Claude is not a lawyer and this isn’t legal advice. For contracts with significant financial or legal consequences, always have a qualified attorney review before signing. But for a first pass — understanding the structure, flagging unusual clauses, knowing what questions to ask your lawyer — Claude is a time-saver.
Prompt for contract review:
“Please review this contract and help me understand it. Specifically:
1. What is the main purpose and structure of this agreement?
2. What are my key obligations under this agreement?
3. Are there any clauses that seem unusual, one-sided, or that I should pay particular attention to?
4. What are the termination conditions — how can each party exit the agreement?
5. Are there any liability limitations or indemnification clauses I should know about?
6. What questions should I ask the other party or a lawyer before signing?
> [paste contract text]”
Claude will walk through each point clearly. For large contracts, you can focus on specific sections: “Tell me more about Section 7 on intellectual property rights.”
For reports and presentations sent to you:
“I’m going to paste a [report/presentation deck/briefing]. Please:
1. Summarize the main argument in 3 sentences
2. List the supporting evidence and how strong each piece is
3. Note any claims that seem unsupported or that you’d want to fact-check
4. Tell me what this is asking me to do or decide
> [paste content]”
Tips and Tricks
Give Claude a role when it matters. Starting with “You are a senior product manager with 10 years of experience in B2B SaaS” changes the depth and framing of Claude’s responses significantly compared to no role. Use this for specialized tasks.
Use the Projects feature for your core clients or projects. Upload your key documents — style guides, briefs, research — and set custom instructions. Every conversation in that Project starts informed rather than starting from scratch.
Ask Claude to think step by step. For complex problems, adding “think through this step by step before giving me your answer” produces more careful, accurate output than asking for an immediate answer.
Request multiple options. Instead of “write this email,” try “write 3 different versions of this email — one formal, one conversational, one very brief.” Having options to choose from is often more useful than getting one version right.
Have Claude critique your own work. “Here’s my proposal. What are its weaknesses? What objections might the reader have? What’s the strongest counterargument to the main recommendation?” This is one of the most underrated uses — using Claude to stress-test your own thinking.
Use extended thinking for hard problems. On Pro and above, you can enable extended thinking mode, which gives Claude more time to reason through complex questions before responding. It’s slower but produces noticeably better output for multi-step problems.
Common Mistakes to Avoid
1. Giving vague, one-sentence prompts for complex tasks
“Help me with my report” will produce something generic. “Here’s my quarterly sales report draft. Rewrite the executive summary to lead with the biggest win, cut the overview section by half, and make the recommendations more specific with owners and dates” will produce something useful.
2. Accepting the first response without refining
Claude’s first answer is rarely the final answer. The most effective users treat Claude like a conversation: “That’s close, but make the tone less formal” or “The third option is the best — can you expand on it?” Iteration is part of the process.
3. Not providing context
Claude doesn’t know your industry, your company, your audience, or your constraints unless you tell it. The more relevant context you include upfront, the better the output without back-and-forth.
4. Using it for calculations without double-checking
Claude can make arithmetic errors. For anything involving numbers you’ll act on — financial calculations, data analysis conclusions, unit conversions in technical specs — verify the math independently.
5. Trusting it for recent events without verification
Claude’s training has a knowledge cutoff, and it doesn’t search the web by default. For current market data, recent news, or anything that changes frequently, verify against current sources. (If you need AI with live web search, Perplexity is a better choice for that specific task.)

FAQ
What’s Claude’s context window size?
Claude currently supports up to 200,000 tokens in the standard interface, which is roughly 150,000 words — enough to process very long documents, extensive code files, or lengthy research. The API and enterprise tiers offer even larger context windows.
Can Claude access the internet?
In the standard interface, Claude does not browse the web. It works from its training data and any documents you paste or upload. For real-time web information with citations, use Perplexity instead. Some Claude integrations through the API can include web search as a tool.
Is Claude confidential? Can Anthropic see what I write?
Anthropic stores conversations for service improvement by default, but offers options to turn off conversation history. For sensitive work — client data, confidential documents, proprietary code — review Anthropic’s privacy policy and consider using the API with a zero data retention agreement if that’s a concern for your organization.
How does Claude compare to ChatGPT for work?
Both are capable. Claude tends to perform better for long document analysis (larger context window), following complex multi-part instructions, and tasks requiring nuanced writing. ChatGPT’s GPT-4o is strong for multimodal tasks and has a more mature plugins/tools ecosystem. For most knowledge work tasks, both perform at a high level and the differences are at the margins.
Can I use Claude for my whole team?
Yes, through the Team plan ($25/seat/month annually for minimum 5 members). This adds shared billing, admin controls, SSO support, and more usage per seat. For larger organizations, the Enterprise plan adds security features, audit logs, and compliance controls.
