Chapter 8: Generative AI Guide: Claude

Claude is a conversational generative AI developed by Anthropic, an AI startup founded by former OpenAI executives. Widely popular for both business and personal use, it has earned a strong reputation for its remarkably natural Japanese phrasing, capacity for handling extensive documents, and robust safety (ethical considerations).

Its defining feature is that it is built around an original safety framework called “Constitutional AI.” This allows the model to autonomously evaluate and appropriately decline or mitigate prompts that raise ethical concerns or copyright risks, making it an easy-to-adopt, trustworthy choice for enterprises.

Compared to other generative AIs like ChatGPT and Gemini, Claude offers the following advantages:

• Remarkably Natural Japanese: With minimal trace of machine translation, it excels at drafting human-sounding text and natural honorifics.
• Bulk Processing of Long Documents (Massive Context Window): You can upload hundreds of pages of research papers, thick technical manuals, or lengthy meeting transcripts (in PDF or Word format) at once to instantly summarize content or spot contradictions.
• The “Artifacts” Feature: When generating code, lightweight web apps, or diagrams, a dedicated window appears on the right side of the screen. There, you can review the source code, preview live interactions (such as web app behavior), edit, and share in real time.
• Image and Document Recognition: In addition to text, you can upload charts, blueprints, or presentation slides and ask targeted questions, such as “Analyze the trend shown in this graph.”

8-1: Getting Started with Claude

Anyone can set it up and begin using it within minutes via a web browser or mobile app.

Step 1: Create an Account

1. Open your web browser and go to claude.ai (mobile apps for iOS and Android are also available).
2. Sign in with a Google account or register by entering your email address.
3. Click the verification link sent to your email.
4. Follow the on-screen instructions to enter your name and complete SMS verification using your phone number (required to prevent spam).

Step 2: Try It Out

• Entering Prompts: Type your questions or instructions into the text box at the bottom of the screen just like talking to someone, then press Send.
• Attaching Files: Use the paperclip icon (or the plus mark) to upload images, PDFs, or text files alongside your questions.
• Starting a New Chat: Whenever you want to switch topics, click “New Chat” in the top-left corner (or menu). This resets the conversation context and prevents the AI from mixing up past details.
