How to use Claude: a beginner's guide

Claude is the other AI worth knowing about. It is made by a company called Anthropic and feels noticeably different from ChatGPT. It writes more like a careful human and handles long documents better. This guide gets you signed up and using it from a standing start.

What makes Claude different from ChatGPT?

Both are AI chat assistants. You type, they answer. The differences are mostly in the personality and what they are best at:

• Writing. Claude generally produces clearer, less generic writing. Lots of writers prefer it for first drafts and edits.
• Long documents. Claude can read very long PDFs and books and answer questions about all of it at once. Bigger memory than free ChatGPT.
• Tone. Claude tends to sound less like a corporate robot. It will admit when it does not know something instead of making things up to seem confident.
• Less hype. Claude does not have built-in image generation in the chat (it can analyze images you upload though).
• Personality. Friendly without being syrupy. Many people find it less exhausting to talk to.

Step 1: Sign up

1. Open a web browser. Go to claude.ai.
2. Click Sign up.
3. Choose Google, Apple, or email signup.
4. Verify your email if needed.
5. Anthropic asks for your phone number to verify you are a real person.
6. Pick a display name. You are in.

Step 2: Try your first question

You see a chat box with the prompt "How can I help you today?" Type anything. Press Enter.

Good first questions to get a feel for Claude:

• Edit this email so it sounds friendlier without being unprofessional: [paste your draft]
• Explain what compound interest is to someone who has never thought about it
• I am 60 and worried about my mom's memory. What should I be watching for?
• Help me prepare for a tough conversation with my brother about Mom's care
• Give me three different opening lines for a wedding toast

Claude is conversational. After it answers, keep going. "Make it shorter." "Try one more, less formal." "Now write a version for my sister to give instead." Iterate until you have what you want.

Step 3: Upload documents (Claude's superpower)

Click the paperclip icon in the chat box. Upload a PDF, Word doc, text file, or photo. Claude can read it and answer questions about it.

Examples that really show off this feature:

• Upload a contract. "Summarize this contract in 5 bullet points. Then tell me anything I should be worried about."
• Upload a medical letter. "Explain this in plain English."
• Upload your resume. "Suggest 3 ways to make this stronger for a marketing manager job."
• Upload a long article. "What are the main points? What do I disagree with?"
• Upload a photo of a clogged dryer vent. "Is this serious? What should I do?"

Free Claude can handle documents up to roughly 200,000 words (a full novel). ChatGPT free is much more limited here.

Step 4: Use Projects (paid feature, worth knowing about)

If you pay for Claude Pro, you can create "Projects" that bundle multiple documents and instructions. Useful if you keep asking about the same things (a job search, planning a wedding, a book you are writing). All your project conversations live together and share the same uploaded files.

Step 5: Use Claude's "Artifacts" feature

When Claude writes anything long (a letter, a code snippet, a webpage), it opens a side panel called an Artifact. You can edit it in place, ask for changes, and download the result. Think of it like a tiny document editor inside the chat.

• Ask: "Write a one-page family newsletter about our move to Watsonville."
• The newsletter opens in a side panel.
• Ask: "Add a section about our new neighbors."
• Watch it update.
• Click the download button to save it as a Word doc or PDF.

What Claude is best at

• Writing and editing emails, letters, blog posts, articles
• Working with long documents (contracts, research papers, instruction manuals)
• Summarizing books, articles, and meeting notes
• Translating between languages with natural-sounding output
• Thinking through a difficult decision out loud
• Coaching for tough conversations (asking your boss for a raise, breaking news to family)
• Explaining complex topics patiently with examples

What Claude is not great at

• Generating images. Claude can analyze pictures but does not make new ones. Use ChatGPT or Gemini for that.
• Real time information. Claude has a knowledge cutoff date (it does not know the news from this week unless told).
• Math with many precise steps. Better, but not perfect.
• Playing music, controlling smart home devices, etc.

Free vs Pro vs Max

• Free: Daily message limit on the smartest model. Switches to a smaller model when you hit the limit. Fine for casual use.
• Pro ($20/month): Higher limits, longer documents, Projects, web search, priority access during busy times. Worth it if you use it for work daily.
• Max ($100 or $200/month): For people who really live in Claude. Massive limits, unlimited Projects, more agentic features. Overkill for most.

Privacy with Claude

By default, Anthropic does not train its AI on your conversations. That is the meaningful privacy difference from ChatGPT, which defaults to using your chats for training unless you turn it off. Still, conversations are stored on Anthropic's servers. Do not paste in Social Security numbers or full account credentials. See our AI privacy guide for a deeper look.

5 things to try once you are signed up

1. Upload a confusing piece of mail (insurance letter, medical bill, tax notice). Ask Claude to explain it.
2. Paste in an email draft you wrote. Ask Claude to make it shorter and friendlier.
3. Upload a long news article. Ask "What are the 5 things I most need to know from this?"
4. Ask Claude to help you prepare for a tough conversation. Practice both sides.
5. Upload a photo of plants in your yard. Ask Claude what they are and how to care for them.

Common beginner mistakes

• Giving up after the first answer. Always iterate. "Shorter." "More direct." "Try a friendlier tone."
• Not giving context. "Help me with my email" is too vague. "Help me write an email asking my landlord to fix the dishwasher. Polite but firm." gets a usable result.
• Trusting it for the news. Claude's free tier does not browse the web in real time unless you enable web search. Always double-check current information.
• Sharing sensitive identifiers. Same caution as any other website.

Should you use Claude, ChatGPT, or both?

Both for free. They are good at slightly different things, and you will quickly notice which one writes the way you like. Many people end up using Claude for writing-heavy work and ChatGPT for images and quick questions. See our full comparison.
