How to use Claude: a practical guide to getting started

Where to start

Go to claude.ai and create an account; a free tier lets you try it with no commitment. The interface is a simple conversation box: you type a request, Claude replies, and you can keep asking follow-ups in the same thread to refine. Start with a concrete task you would have done yourself (summarise a text you paste in, draft an email, explain a concept) rather than an abstract question. Keep each conversation focused on one topic: open a new thread when you switch tasks, so the context does not get mixed up and answers stay relevant.

Writing good instructions

Answer quality depends mostly on how clear the request is. Give context (who it is for, what the goal is), specify the expected format (list, table, paragraph, length) and the tone you want. You can paste an example of what you expect: Claude uses it as a template. If the first answer is not quite right, do not start over: say what is wrong (too long, too formal, a point is missing) and ask for a revision. This iterative back-and-forth is often faster than trying to write a perfect prompt on the first try.

Analysing files and documents

Claude can read documents you give it (PDFs, text, images, screenshots) and work on them: summarise a report, pull the key points from a contract, compare two versions, answer precise questions about the content. For long texts, its large context window lets it handle a lot of material at once. Good practice: ask for quotes or page numbers when possible, and check critical passages against the source. Claude is an assistant, not an authority: on legal, medical or financial topics it helps you get oriented but does not replace a professional.

Going further: Claude Code, API and MCP

For developers, Claude Code is a command-line tool that reads your repository, edits files and runs tests right in the terminal. Anthropic's API lets you build Claude into your own applications, billed per usage (per token). The MCP (Model Context Protocol) connects Claude to external data sources and tools in a standardised way. You do not need any of this to get started, but it is worth knowing as your usage becomes more professional. To follow new features and model releases, check the Claude News feed.

Is Claude free?

Yes. Claude offers a free tier on claude.ai, with usage limits, which is enough to explore the tool. Paid plans (such as Pro and Max) raise the limits and unlock the most capable models. Exact pricing changes over time: check it on claude.ai.

Do I need to install anything to use Claude?

No, not necessarily. Claude runs directly in the browser at claude.ai. There are also desktop and mobile apps, plus Claude Code for developers, but those are optional: basic use requires no install.

How do I get better answers from Claude?

Give context, specify the expected format and tone, and provide an example if you can. If the answer is not perfect, fix it through iterations rather than starting over. Keep one conversation per topic for more precise answers.

Is my data kept private?

Anthropic publishes its privacy and data-handling policies, which differ depending on whether you use the consumer tier, the API or enterprise plans. For sensitive data, read the current policy on anthropic.com and favour the plans designed for that.
