How to Use Claude AI: A Beginner's Guide (2026)
To use Claude, sign up for a free account on the website or app, type a clear request, and upload a document if you want it to work from your own material. Claude is often chosen for reading long documents and careful writing. Give it a role, context, a task and a format, ask it to quote or point to the text it used, and check anything important yourself. You do not need to code.
Claude is an AI assistant made by Anthropic. People use it to read long documents, draft and edit writing, analyse information and think through problems. This guide covers how to start, what to try first, how to work with your own documents, and how to avoid common mistakes. Plans, limits and features change, so confirm them on Anthropic's own pages.
Get started
- Create an account on the Claude website or app and start with the free plan.
- Type your request in plain language, as if briefing a capable assistant.
- Add files if you need them. You can upload documents so Claude works from your material instead of from memory.
- Reply with changes such as "shorter", "more formal" or "show this as a table".
- Check the usage limits. Free plans have limits that can end a long session early.
Write prompts Claude handles well
Use the same five-part structure that works in any assistant: role, context, task, format and limits. Claude responds well to clear instructions and to examples of the style you want.
If you are new to prompting, our free seven-day prompting plan gives you a practice project each day.
Ten things to try first
| Task | Try this |
|---|---|
| Summarise a long report | Upload it and ask for findings with quotes |
| Edit your writing | Paste a draft and ask for a clearer version and a list of changes |
| Compare two documents | Upload both and ask for differences in a table |
| Prepare for a meeting | Paste notes and ask for decisions, owners and next steps |
| Learn a topic | Ask it to explain step by step, then quiz you |
| Draft an email or post | Give the audience, goal and tone |
| Think through a decision | Ask for options, trade-offs and what would change its view |
| Challenge your idea | Ask it to argue the strongest case against it |
| Analyse data you paste | Ask for trends, then check the calculations |
| Create a reusable template | Ask it to turn your best prompt into a fill-in-the-blank version |
Working with your own documents
Claude is popular for long documents such as reports, contracts and annual reports. A good routine is:
- Upload the document from an official source.
- Ask specific questions rather than "summarise everything".
- Ask it to cite the page or quote the text it used.
- Open those pages yourself and confirm the numbers.
- Ask follow-up questions about anything that looks odd.
For a worked example with financial documents, see our guide to uploading an annual report to Claude and our step-by-step Claude research workflow. Very long documents can exceed what a model reads at once, which is explained in our glossary entry on the context window.

Claude lets you group related chats and files so you do not repeat yourself. Use a separate space for each ongoing topic, such as a research project or a client, and add the files and instructions that topic always needs. Features and names change, so check Claude's help pages for the current options.
What to watch out for
- It can still be wrong. Verify names, numbers, dates and quotes. See AI hallucination.
- Usage limits. Long sessions and big files use more of your allowance.
- Privacy. Do not upload confidential or personal documents unless you have permission and have checked the data settings.
- Not professional advice. Do not rely on it alone for medical, legal, tax or investment decisions.
