What is Claude — Anthropic, and what can you do with it?

What is Claude, and what is it used for?

Claude is Anthropic’s AI assistant. You can use it to write, analyze documents, get explanations on topics, program, and research information. You give commands in plain language and work toward a usable result through follow-up questions, while verifying key facts and the final output yourself.

What is Claude by Anthropic?

Claude is a generative artificial intelligence application: software that can create brand new content based on your query. This could be an answer, a summary, a first draft of a text, or programming code. You interact with Claude through conversation, without needing to know any technical commands.

A simple question can be enough. For example: “Explain this concept to someone with no prior knowledge.” You can also work more extensively, using your own documents, examples, and conditions. In that case, Claude becomes more of a work tool that helps you process material than a chatbot that answers isolated questions.

Anthropic is the company behind Claude. The names therefore refer to different things. Anthropic develops the technology; Claude is the name of the AI assistant and the associated family of AI models.

This distinction explains why you might encounter Claude in multiple places. You can work directly with the assistant, but developers can also integrate the underlying models into other software. Therefore, not every application featuring Claude offers the same features.

Claude is more than just an automated response platform

The practical value often lies in editing what you already have. A messy collection of notes becomes a presentable proposal. A difficult manual becomes an understandable explanation. A long text becomes an overview where the relevant points can be found more quickly.

You can always make adjustments along the way. “Shorter” is possible, but “keep the exceptions and remove the repetition” provides more direction. So you don’t have to formulate the perfect prompt right away. A conversation helps refine the result.

Who is behind Claude?

Anthropic is an AI company that combines research and product development. In its mission statement, the company emphasizes reliable, understandable, and controllable AI systems. Dario Amodei and Daniela Amodei are among the co-founders.

This focus on safety is relevant to the way Anthropic develops its products. However, it doesn’t mean that every answer Claude gives is automatically correct. Even a platform designed for reliability can misinterpret information or make a convincing-sounding mistake.

For users, what matters most is what that technology actually delivers in their own work. Can you understand a document more quickly? Are the facts preserved when you have a text rewritten? Do you understand better how something works after the explanation? Those are more meaningful questions than simply how impressive a demonstration looks.

What can you do with Claude?

Claude supports a wide range of language, analysis, and programming tasks. The overview below provides an initial overview. The examples are possible tasks; they do not guarantee that every result will be usable without modification.

Writing, rewriting, and translating texts

Claude can help when you know what you want to say but haven’t quite found the right wording yet. You provide the facts, specify the audience, and ask for a suitable text. This could be a business email, a product description, a cover letter, or an article.

When rewriting, you can specify exactly what needs to be retained. Perhaps a text should be made more accessible, while the technical terms remain necessary. Or you might want a friendlier customer response without introducing brand new commitments.

Rewrite this customer email in clear Dutch. Keep all amounts and terms unchanged. Make the tone friendly, but do not add any discounts, refunds, or other promises.

Translation services are also available. Please let us know the purpose of the translation. A formal email to a French client requires different wording than an informal message. If necessary, leave names, product names, and established terms explicitly unchanged.

The final check focuses on content. A sentence might have been polished but could now imply something different. This is especially important to keep in mind when proofreading commercial texts.

Summarizing and comparing long documents

Claude can work with supported documents, including PDF and Word files. You can ask for a summary or request a targeted search for specific information. What obligations are included in this proposal? How do the versions differ? Which questions remain unanswered?

A specific reading assignment often yields better results than “summarize everything.” A salesperson looks for different information in a report than a finance employee does. Therefore, please specify why you need the summary.

Example: Preparing two proposals for a meeting

Suppose you receive two proposals with different structures. Ask Claude to compare the included services, exclusions, deadlines, and open questions side by side. Have him mark any missing information as such.

This creates a useful checklist for vendors. That’s often more valuable than immediately determining which quote is “the best” when the terms aren’t yet comparable.

Processing also depends on the file type and structure. A document containing poorly legible scans or complex tables requires extra attention. If there are important findings, ask for a reference to the relevant passage.

Making Complex Topics Easy to Understand

You can use Claude to tailor explanations to your prior knowledge. For example, ask for a brief definition, then a concrete example, and finally a review question. This will help you determine more quickly whether you truly understand the topic.

This can be helpful while studying, but also at work. A brand new employee might understand an internal process better through a relatable work scenario than through a formal description.

Explain this concept to a beginner. Use one everyday example. Then ask me a question so I can check whether I understand the difference from the related concept.

When learning, the explanation deserves attention, not just the final answer. Let Claude point out where your own reasoning differs from the course material. That way, you can keep track of the step that isn’t clear yet.

Explore ideas and critically evaluate a proposal

An initial idea is rarely a fully developed plan right away. Claude can help you come up with alternatives, formulate questions, and identify weaknesses. For example, you can have the platform respond from the perspective of a customer who isn’t yet familiar with your product.

Plus, you don’t have to sift through an endless list. Three clearly distinct options are often easier to evaluate than twenty minor variations on the same idea.

Also ask for counterarguments. What information is missing? Which assumption hasn’t been examined yet? A proposal doesn’t become stronger just because an AI assistant enthusiastically confirms it. It becomes stronger when you discover what still needs to be investigated.

Understanding and Implementing Programming Code

Claude can write code, explain existing code, and help troubleshoot errors. This makes it useful for developers, but also for anyone who wants to understand what a small script does.

A beginner can ask for an explanation of an error message. An experienced programmer can ask for feedback on a change or to weigh different solutions. Always specify the environment you’re using and the relevant versions so that the explanation can be tailored accordingly.

In addition to the standard chat application, there’s Claude Code, a software development tool that can work with project files and development tools. It goes beyond just a code snippet in a chat window.

A generated solution should, however, be tested within the actual project. Code that seems logical on its own may conflict with existing conventions, dependencies, or exceptions.

Discussing images and graphs

Claude can interpret images you provide, such as a screenshot, a graph, or a photo of a document. You can ask what’s visible, what information stands out, or which parts remain unclear.

The quality of the material matters. Small print, truncated axes, or a missing legend can make interpretation difficult. Whenever possible, also include the genuine figures if a conclusion depends on them.

A practical exercise, for example, is: “First describe what you actually see, and only then offer possible explanations.” This helps to distinguish between observation and interpretation.

How does a conversation with Claude work?

Claude uses AI models that have learned patterns in language and other information. A response is generated based on your prompt, the available conversation context, and any available resources. The answer is therefore not simply a pre-written text pulled from a catalog.

That’s why context influences the result. A brief question about a “proposal” leaves a lot open to interpretation. If you specify who the proposal is intended for, what agreements have already been made, and how long the text should be, the answer will have clearer boundaries.

The same applies to follow-up questions. Within the available context, Claude can build on previous content. You can ask for a part to be modified, have a choice explained, or request a different format.

A useful assignment primarily provides direction

You don’t need to learn any complicated command-line techniques to get started. These four elements usually provide a good foundation:

• Goal: What do you want to be able to use afterward?
• Content: What text, facts, or files are relevant?
• Boundaries: What must be preserved or left blank?
• Format: Would you like an explanation, a table, a draft text, or a questionnaire?

“Make this better” can mean many things. “Make this explanation understandable for brand new customers while retaining the installation requirements” is easier to evaluate. It’s also easier to see afterward whether the instructions were followed.

What features make Claude practical for longer work sessions?

Projects: Keeping Materials and Context Together

With Projects, you can organize work related to a specific topic—such as relevant files, instructions, and conversations for a client, research, or writing project. This way, you’ll have to resubmit the same background information less often.

It helps to establish consistent guidelines for recurring elements: who you’re writing for, which source is authoritative, and which product names you use. A project runs more smoothly when the material remains up-to-date and well-organized. Five conflicting versions of the same manual don’t make an assignment any clearer.

Artifacts: View and edit results separately

Artifacts are results that Claude can display alongside the conversation, such as a document, presentation, product type, or small interactive application. This is useful when you want to develop something that needs to be usable outside of the conversation as well.

For example, you can discuss a layout in the chat and view the result right next to it. Then you can make targeted changes: move an element, refine some text, or try a different layout.

A polished presentation doesn’t necessarily guarantee accuracy. Even with a well-prepared document or a working prototype, you still need to assess whether the content and behavior align with your intentions.

Web Searches and Research

Claude can use available web search functions to retrieve up-to-date information and provide source references. This makes a difference when it comes to topics where built-in model knowledge alone isn’t sufficient.

For more detailed queries, there’s also a search function that can combine multiple search criteria. Availability depends on your subscription and work environment.

Make it clear in advance what kind of evidence you’re looking for. For product terms and conditions, for example, you’ll want the information from the provider. For a comparison, the publication date and comparable criteria are important. A source reference is a starting point for verification, not automatic confirmation.

Integrations with other applications

Through available integrations, Claude can work with information and features from other applications. What’s possible depends on the connection, the access granted, and any organizational settings.

The key difference is that you have to manually enter less information. At the same time, it must remain clear which information is being used and which action is being performed. Preparing a draft and actually sending that draft are two different tasks.

Who is Claude a good fit for?

Claude is especially worth checking out if you regularly need to process information or want to turn raw data into a usable result. You don’t need a technical background to use it.

For self-employed individuals and small businesses, this could include customer communication, work instructions, and organizing loose notes. A practical first use case is a recurring task where you can easily assess the quality yourself.

Writers and communications professionals can rely on Claude to help with structuring, editing, and developing different perspectives. Genuine interviews, examples, and content choices remain key to creating a distinctive text.

Students and educators can have explanations and practice materials prepared. Of course, the policies of the educational institution apply. A summary is especially useful when you can use it to refer back to the genuine course material.

Developers and analysts can seek support regarding code, data, and technical documentation. Their expertise remains essential for evaluating assumptions and verifying results.

Can Claude work in Dutch?

Yes, you can speak to Claude in Dutch and ask for answers in Dutch. The language of the conversation does not have to match the language of the buttons and menus.

Feel free to specify which version you’d like. A text for Flemish customers may require different wording than one for Dutch readers. You can also specify the form of address, technical terminology, and desired level of simplicity.

When translating or rewriting, it’s worth doing a quick final edit. Be sure to check local terms, expressions, and words with specific meanings within your company.

What is the difference between Claude and ChatGPT?

Claude and ChatGPT are AI assistants from different providers: Claude is from Anthropic, and ChatGPT is from OpenAI. With both, you can ask questions and carry out tasks using natural language.

It’s not very helpful to name a single “best” option. Models, features, and subscription plans change. Moreover, one application might be a better fit for your documents or work style than another’s.

Therefore, compare them using the same recognizable task. Use identical source material and the same conditions. Then assess what you actually receive: Are facts preserved? Are missing details noted? And how much editing or proofreading is required?

An answer that’s more pleasant to read isn’t necessarily better substantiated. For business use, what matters most is how much usable work you’re left with after the audit.

What are the limitations of Claude?

Claude may provide incorrect or misleading information. Anthropic acknowledges this itself. Such an error is often called a “hallucination ”: the answer sounds plausible, but a fact, quote, or connection is incorrect.

In addition, a summary may omit an important exception. A comparison may mix up different time periods. A neat table may give the impression that all data was available, when in fact some values were based on assumptions.

Therefore, use a verification method that suits the task at hand. For a birthday message, focus primarily on tone and content. For a contract or important calculation, compare the result with the source material and, if necessary, have an expert review it.

Use only the information provided. Distinguish between established facts, your interpretation, and missing data. For every important conclusion, condition what it is based on.

Furthermore, share only the material you need for the assignment and are authorized to use. When it comes to business documents, you must take into account the applicable agreements regarding data processing.

How can you tell if Claude is a good fit for your work?

Start with a small, straightforward task so you can assess for yourself whether the result is satisfactory. For example, choose an existing explanation that needs to be shortened, a non-confidential document you’re familiar with, or a few notes that need a clear structure.

First, request one usable result. Then provide specific feedback and see if the next version is an improvement. This way, you’ll not only experience the initial response but also how smoothly the collaboration goes.

Claude offers a free version with usage restrictions as well as paid subscriptions. So you don’t have to choose a comprehensive subscription right away to get a first impression. Only then should you assess which features and capabilities you actually need.

The best initial test is a task from your own workday. If, after checking, you find that it’s completed faster or more clearly, you have a concrete reason to look into it further.
