How to Use Claude? 2026 Claude AI Feature Tutorial & Tips Guide

You've Probably Been Using ChatGPT, But Claude Is Worth a Try

Let's start with the conclusion: Claude is not a ChatGPT clone.

It has its own strengths — handling ultra-long documents, writing clean code, and proactively telling you "I'm not sure" instead of making things up.

If you're already using ChatGPT, this article will show you where Claude can do better. If you've never used an AI assistant, this article will take you from zero.

No technical background needed. No payment needed. Just open your browser and start.

TL;DR

Claude has three usage modes: free web version (claude.ai), Pro subscription ($20/month), and API integration (for developers). The most powerful features include long document processing (200K Context), code generation, and structured analysis. Using prompt techniques can dramatically improve output quality.

Free Claude Usage & Limitations | Use It Without Spending a Dime

Answer-First: Register an account at claude.ai to use the Claude Sonnet model for free. The free version has daily message limits, but it's more than enough for general use.

How to Get Started for Free

1. Open claude.ai
2. Sign up with a Google account or email
3. Start chatting

That's it. No credit card, no software download needed.

What Can the Free Version Do?

• Q&A conversations
• Document summaries (upload PDFs, text files)
• Writing assistance (articles, emails, reports)
• Code generation and debugging
• Translation (multilingual)
• Brainstorming and analysis

Free Version Limitations

Complete Claude Core Feature Tutorial | Features You Need to Know

Answer-First: Claude's five most valuable features — long document analysis, code generation, Artifacts (live preview), structured output, and multilingual capability.

Feature 1: Long Document Analysis (200K Context Window)

This is one of Claude's biggest competitive advantages.

You can upload an entire contract, technical document, or academic paper at once and have Claude summarize it, find key points, or answer questions.

How to use:

1. Click "Attach file" at the bottom of the chat box
2. Upload a PDF or text file
3. Ask what you want to know

Practical examples:

• "Summarize the top five risk clauses in this contract"
• "What does this technical document say about API rate limits?"
• "Compare the main differences between these two documents"

Feature 2: Code Generation & Debugging

Claude excels at code-related tasks, especially Python, JavaScript, and TypeScript.

Things you can ask Claude to do:

• Write a feature from scratch
• Explain code you don't understand
• Help you debug
• Refactor existing code
• Write test cases

Usage tip: Paste the complete error message and relevant code to Claude. The more complete the context, the more precise the answer.

Feature 3: Artifacts — Live Preview

Artifacts is a unique Claude feature. When Claude generates code, HTML pages, or SVG graphics, it displays a live preview in the right panel.

Ideal scenarios:

• Create a simple web page prototype
• Generate charts or data visualizations
• Build interactive calculation tools

Feature 4: Structured Output

Claude is great at organizing information into tables, lists, or specific formats.

Practical examples:

• "Organize this text into a Markdown table"
• "Output the following information in JSON format"
• "Create a comparison list of pros and cons between A and B"

Feature 5: Multilingual Capability

Claude supports dozens of languages, including Chinese, English, Japanese, Korean, and more.

In terms of Chinese, Claude's performance is already quite fluent, especially with Traditional Chinese phrasing that feels more natural than GPT (subjective opinion, individual experience may vary).

10 Practical Claude Prompt Tips | Make AI Responses 10x Better

Answer-First: Prompt quality directly determines AI response quality. The following 10 tips can dramatically improve Claude's output.

Tip 1: Give a Clear Role

Bad prompt: "Help me write a letter"

Good prompt: "You are a professional business consultant. Please help me write a follow-up quotation letter to a client. The tone should be professional but not cold."

Tip 2: Specify Output Format

"Please answer in the following format:

1. Summary (50 words or less)
2. Key Points (bullet list, 3-5 points)
3. Recommended Actions (1-2)"

Tip 3: Provide Examples

"Please write a product description for me. Here's an example of a style I like: [paste example] Please write my product description in a similar style."

Tip 4: Request in Steps

Don't dump everything at once for complex tasks. Let Claude do step one first, confirm the direction is right, then continue.

Tip 5: Ask Claude to Think

"Before answering, please list your thought process and considerations first, then give your final recommendation."

Tip 6: Set Constraints

"Please answer in 200 words or less." "Use only English." "Don't use technical jargon — use language that everyday people can understand."

Tip 7: Ask for Comparisons and Trade-offs

"Please compare the pros and cons of A and B, and explain under what circumstances you should choose which one."

Tip 8: Let Claude Admit Uncertainty

"If you're not sure about certain information, please tell me directly that you're not sure. Don't guess."

Claude already tends to acknowledge uncertainty, but adding this instruction makes it even more effective.

Tip 9: Iterate and Refine

Not satisfied with the first response? Don't start over — just tell Claude what needs to be changed.

"The previous answer was too long. Please cut it in half." "Point three isn't specific enough. Please add numbers and examples."

Tip 10: Upload Reference Materials

Instead of describing context in text, just upload the document. Claude understands files better than your descriptions.

FAQ: Common Claude Usage Questions

Does Claude cost money?

Claude.ai basic version is free.

• Free version: Access to Sonnet model, daily message cap
• Pro version: $20/month, more messages, access to Opus
• API: Pay per usage, requires separate setup

Can Claude handle file uploads?

Yes. Claude supports uploading:

• PDF documents

• Code files (.py, .js, etc.)
• Images (.png, .jpg)

Limitation: The free version has file size and quantity limits; Pro version limits are more generous.

Does Claude remember previous conversations?

Within the same conversation thread, Claude remembers previous content.

But across different conversation threads, it does not remember. Each new conversation is a fresh start.

Pro version has a Projects feature that allows setting up persistent background knowledge.

Are Claude's answers accurate?

Claude's answers are mostly accurate, but not guaranteed to be 100% correct.

One advantage of Claude is that it's more willing to tell you "I'm not sure" or "this information may need verification," rather than confidently giving wrong answers.

Recommendation: Don't rely solely on AI responses for important decisions. Always verify independently.

Can Claude be used in Chinese?

Yes. Claude's Traditional Chinese capability in 2026 is quite mature. You can ask questions directly in Chinese, and Claude will respond in Chinese.
