How to Use Anthropic Claude, ChatGPT’s AI Rival

Anthropic Claude is an AI chat assistant you can use to draft, explain, summarize, brainstorm, and work with supported files. To get started, open Claude in a browser or its official app, sign in, and send a clear prompt; you can then refine the response in the same conversation.

What You’ll Need

• An internet-connected computer or mobile device and a current browser, or the official Claude app where available.
• An Anthropic account. Sign-in methods and access options can vary by location and may change.
• A task or question, plus any relevant text or supported file you want Claude to consider. Avoid sharing passwords, payment details, or other sensitive information.

Step-by-Step

1. Open Claude through an official route. Visit Claude’s official website or install its official app from your device’s app store. Check the publisher and web address before signing in. Availability, features, and account requirements can differ by country and platform.
2. Create an account or sign in. Follow the on-screen prompts and use an available sign-in method. Complete any verification requested by the service. If you already have an account, sign in rather than creating a duplicate.
3. Start a new conversation. Select the option to begin a chat, if one is not already open. A fresh conversation is useful when you are changing subjects; a continuing conversation can be useful when Claude needs earlier details from the same task.
4. Write a specific prompt. Explain what you want, provide context, and state the desired format. For example: “Summarize the following meeting notes in five bullet points. Keep the decisions and action items separate.” Include the audience, tone, length, and constraints when they matter. Put source material in the prompt or attach it if file upload is available.
5. Send the prompt and review the answer. Submit it using the send control. Read the whole response, checking names, dates, figures, quotations, and any claims that matter. Claude can make mistakes or misunderstand incomplete instructions, so do not treat a confident tone as proof.
6. Ask a follow-up to improve the result. Tell Claude exactly what to change: “Make this shorter,” “Show the assumptions,” or “Use a table with these three columns.” Correct any mistaken premise and add missing context. You can ask it to explain its reasoning or identify uncertainty, but verify important conclusions independently.
7. Use files or images when appropriate. If your account and interface offer attachments, choose the upload control and select a supported file. State what you want Claude to do with it, such as extract headings or compare two sections. Confirm that the file has finished uploading, and check the response against the original because formatting or content may not be interpreted perfectly.
8. Copy, save, or export useful work. Use the interface’s available copy or download options, or paste the result into your own document. Review the final text before using or sharing it. Do not assume a chat is your only copy or that its retention settings match your needs.
9. Manage the conversation and account settings. Start a separate chat for an unrelated task to reduce confusion. Review the service’s current privacy, data, and chat-history controls in its settings and official help materials. Choose settings that fit your needs, and avoid entering information you would not want handled by an online service.

Common Mistakes

• Asking something too broad. “Help with my project” gives little direction. State the goal, background, constraints, and the kind of answer you need.
• Leaving out important context. Claude may not know which audience, document, or definition you mean. Include the relevant details, and specify what it should not assume.
• Accepting the first answer without checking. Verify factual, technical, or time-sensitive claims with reliable sources, especially before acting on them or publishing them.
• Sharing confidential material casually. Do not paste private records or credentials unless you are authorized and have checked the relevant privacy terms and controls. Remove unnecessary identifying details.
• Expecting every feature to be available. File uploads, usage limits, and other capabilities may depend on the interface, account, region, or current service terms. Check what your screen actually offers.
• Starting over when a follow-up would work. If the answer is close, clarify what is wrong in the same chat. Conversely, open a new chat when old context could confuse a different task.

Tips

• Give Claude a role only when it helps define the task, such as “Act as an editor” or “Explain this for a new learner.” A role does not make its response authoritative.
• Ask for a specific output structure: a checklist, comparison table, outline, or plain-language explanation. State a useful length or number of items.
• For long work, split the task into stages: first request an outline, then revise it, then ask for a draft. This makes it easier to catch misunderstandings early.
• When asking about provided material, say “Use only the text below” if you want a source-limited response, then verify that the answer is supported by the material.
• If you need current information, ask for sources or dates where the interface supports them, and check the source pages yourself. A chat answer may not reflect the latest changes.
• Keep your own copy of important output and record any edits you make. Treat Claude as a drafting and research aid, not a replacement for your judgment.

Troubleshooting

• The site or app will not load: Check your connection, reload the page, and try another current browser or the official app. Confirm you used the official route and check the service’s status or help page if the problem continues.
• You cannot sign in: Check that you selected the same sign-in method used for the account, and follow the official account-recovery prompts. Look for verification messages in your inbox and spam folder. Never share a sign-in code with someone claiming to provide support.
• A message will not send or a response stops: Check your connection and whether the interface shows a limit or service issue. Try a shorter prompt, send it again, or wait and retry. Save any text you have already written before refreshing.
• An answer misses the point: Restate the goal in one sentence, add the missing background, and specify the output format. If the conversation has accumulated unrelated details, open a new chat and include only the context needed.
• An attachment is rejected or misunderstood: Check the interface’s supported file types and size limits, then try a supported file or paste a short relevant excerpt. Make sure the upload completed and ask about a specific section rather than the whole file at once.
• You suspect a factual error: Ask Claude to identify its assumptions and provide a way to verify the claim. Check trustworthy primary sources independently; do not use an unverified answer for consequential decisions.
