What Is Claude?
Claude is an AI assistant built by Anthropic, a company founded by former members of OpenAI. If ChatGPT is the AI tool everyone has heard of, Claude is the one that AI professionals and power users increasingly prefer for complex, nuanced work.
I use Claude extensively in my consulting practice, and I recommend it to clients who need AI for anything beyond basic question-and-answer tasks. Here is why, and how to get the most out of it.
Why Claude Is Worth Your Attention
Claude has several distinctive strengths that set it apart from other AI tools:
Longer context window. Claude can process and remember much larger amounts of text than most competitors. This means you can upload entire documents, lengthy reports, or extensive datasets and have meaningful conversations about them. For business users, this is transformative. You can paste a 50-page contract and ask Claude to identify specific clauses, summarise the key terms, or flag potential issues.
Nuanced writing. Claude consistently produces writing that sounds more natural and less formulaic than other AI tools. It handles tone shifts well, maintains consistency across long pieces, and avoids the "AI voice" that makes some generated content immediately identifiable.
Careful with facts. Claude is more likely to acknowledge when it does not know something rather than confidently making up an answer. For business applications where accuracy matters, this is crucial.
Strong analytical reasoning. Complex analysis, strategic thinking, and multi-step reasoning are areas where Claude excels. When I need to think through a business problem, Claude is usually my first choice.
Code and technical capabilities. Claude is excellent at writing, reviewing, and debugging code. If your business involves any software development, this is a significant advantage.
Getting Started
Setting Up Your Account
- Go to claude.ai and sign up with your email address or Google account.
- You will immediately have access to the free tier.
- To upgrade to Pro ($20/month), click on your profile and select your plan.
The free tier is useful but has significant rate limits, especially during peak usage times. If you plan to use Claude regularly for work, the Pro subscription is worth it.
The Interface
Claude's interface is clean and straightforward. You will see a text input area at the bottom and your conversation above. Key features to know about:
Conversations (Projects): Each conversation is separate. Claude does not remember previous conversations unless you tell it to. For ongoing projects, keep a single conversation going rather than starting fresh each time.
File uploads: Click the paperclip icon to upload documents. Claude can read PDFs, Word documents, text files, images, and code files. This is one of its most powerful features for business use.
Artifacts: Claude can create and display rich content like code, documents, and visualisations in a side panel. This is particularly useful for reviewing longer outputs without them getting lost in the conversation.
Projects: You can create project spaces with custom instructions and uploaded knowledge files. This is extremely useful for business applications, as I will explain below.
Essential Prompting Techniques for Claude
Claude responds to prompting techniques similarly to other AI tools, but there are some approaches that work particularly well with it.
Be Specific About Your Needs
Claude thrives on specificity. The more detail you provide about what you want, the better the result.
Compare these two prompts:
Generic: "Help me write a business proposal."
Specific: "I run a 10-person digital marketing agency in Manchester. I need to write a proposal for a potential client (a chain of 5 dental practices in the North West) for a 6-month SEO and content marketing campaign. Our fee would be £3,000/month. The proposal should be professional but approachable, about 4 pages, and include: executive summary, understanding of their market, proposed strategy, deliverables and timeline, pricing, and next steps. The client mentioned they are currently getting most of their new patients through Google but want to increase their online visibility."
The second prompt gives Claude everything it needs to produce something genuinely useful.
Use System Prompts via Projects
Projects allow you to set persistent instructions that apply to every conversation within that project. Create a project for your business and include:
- Your company information, services, and target market
- Your preferred communication style and tone
- Specific terminology or phrases you always use (or avoid)
- Any standard formats or templates
This means every conversation starts with Claude already understanding your context, saving you from repeating the same background information every time.
Ask Claude to Think Step by Step
For complex problems, explicitly ask Claude to think through its reasoning. Phrases like "think step by step," "break this down into stages," or "walk me through your reasoning" produce significantly better analytical output.
This is particularly effective for business strategy questions, financial analysis, and any task where the process matters as much as the answer.
Give Claude a Role
"You are a senior financial analyst reviewing quarterly results for a mid-size UK retailer" will produce dramatically different (and better) output than a generic request for financial analysis. Match the role to your specific need.
Use the Extended Context
One of Claude's biggest advantages is its ability to work with large amounts of text. Take advantage of this:
- Upload your entire company handbook and ask Claude to draft policy updates based on it
- Paste all your customer reviews from the past quarter and ask for a thematic analysis
- Upload a competitor's website content and ask for a competitive positioning analysis
- Share meeting transcripts and ask for action items, decisions made, and open questions
Business Use Cases Where Claude Excels
Document Analysis and Review
This is where Claude really shines. Upload contracts, reports, research papers, or any long document and ask Claude to:
- Summarise the key points
- Identify risks or issues
- Compare it against a standard template or checklist
- Extract specific data points
- Rewrite sections in plain English
I have used this with clients in legal, finance, and property management. The time savings are substantial. A contract review that used to take a junior associate four hours can be done in 30 minutes with Claude doing the first pass.
Strategic Planning and Analysis
Give Claude context about your business, your market, and your goals, and use it as a strategic thinking partner. It can:
- Run SWOT analyses
- Evaluate business opportunities
- Identify risks you might have missed
- Play devil's advocate on your plans
- Model different strategic scenarios
The quality of strategic output from Claude is genuinely impressive when you provide sufficient context. I use it regularly to pressure-test recommendations before presenting them to clients.
Writing and Content Creation
Claude produces high-quality long-form content, including:
- Blog posts and articles
- White papers and reports
- Email sequences and marketing copy
- Proposals and pitches
- Internal communications and policies
Its ability to maintain consistent tone across long pieces and adapt to different brand voices is noticeably stronger than most alternatives.
Code and Technical Projects
If your business involves any software development, Claude is a powerful coding assistant. It can:
- Write code in virtually any language
- Debug existing code
- Explain complex codebases
- Suggest architectural improvements
- Create documentation from code
The Artifacts feature is particularly useful here, as code appears in a clean, formatted panel where you can review and copy it.
Data Analysis
Upload CSV files, spreadsheets, or datasets and ask Claude to analyse them. It can identify patterns, generate insights, create summaries, and even produce visualisations through its code execution capabilities.
For small to medium datasets, this is faster and more flexible than most dedicated analytics tools, especially when you want narrative insights rather than just charts.
Claude vs. ChatGPT: An Honest Comparison
People ask me this constantly, so here is my straightforward take:
Choose Claude when you need:
- Long document analysis (larger context window)
- Nuanced, natural-sounding writing
- Complex reasoning and analysis
- Accuracy and careful handling of uncertainty
- Code review and development
Choose ChatGPT when you need:
- Web browsing and real-time information
- Image generation (via DALL-E)
- A broader ecosystem of plugins and integrations
- Quick, casual interactions
- Custom GPTs from the GPT Store
The honest truth: For serious business use, I recommend having both. They each have situations where they are the better tool. Claude Pro and ChatGPT Plus cost the same ($20/month each), and together they cost less than a single hour of most professional services. The productivity gains easily justify both subscriptions.
Tips for Getting Better Results
- Start conversations with context. Do not assume Claude remembers anything from previous chats. Provide relevant background at the start.
- Iterate. Your first prompt rarely produces the perfect result. Refine through follow-up instructions.
- Use file uploads extensively. Claude's ability to work with your actual documents is one of its greatest strengths.
- Be explicit about format. Tell Claude exactly how you want the output structured: bullet points, numbered lists, paragraphs, tables, headers.
- Ask for alternatives. "Give me three different approaches to this" often produces better results than asking for a single answer.
- Fact-check important claims. Claude is better than most AI at accuracy, but it can still make mistakes. Verify anything you are going to rely on for business decisions.
- Set up Projects for recurring work. The upfront time investment in creating a well-configured project pays off enormously in the quality of subsequent conversations.
Getting Your Team Started
If you want to roll out Claude across your business:
- Start with a small pilot group (3 to 5 enthusiastic early adopters)
- Give them Pro subscriptions and set up shared Projects with company context
- Run a 2-hour training session covering the techniques in this guide
- Ask each person to track time saved over 30 days
- Use the results to justify broader rollout
I run exactly this kind of training programme for UK businesses. If you want to accelerate your team's AI adoption, book a call and we can discuss the best approach for your situation.
