Supported Languages

Claude performs best in English but supports many other languages. You can switch languages in the settings menu. Claude also understands programming languages and can read documents like PDFs or spreadsheets.

Chat Like a Pro

Claude’s conversational interface is designed for natural, human‑like dialogue. Let’s learn how to get the most out of chat interactions.

How to Communicate with Claude

• Be clear and specific – Specific questions lead to more precise answers. For example, instead of asking “Tell me about marketing,” ask “What are three social‑media strategies for B2B startups?”

• Use follow‑up prompts – Refine Claude’s output by asking follow‑up questions or requesting reformatting (e.g., “Summarize that in bullet points”).

• Include context – Provide background information or attach files (up to 20 per chat, 30 MB each) to help Claude generate more relevant responses.

• Adjust tone or style – Ask Claude to write in a specific voice—formal, friendly, persuasive or technical. You can even ask it to emulate your writing style by providing a sample.

Shortcut: Use the **slash command /restart or start a New Chat when you want Claude to forget the current context and start fresh.

Asking Questions & Getting Answers

Claude can answer a wide range of questions—from simple factual queries to complex problem‑solving. Here are examples:

Watch Out! While Claude is highly accurate, it can occasionally produce incorrect or outdated information. If you’re making decisions based on its output, double‑check facts—especially for time‑sensitive or critical topics.

Conversational Tips

• Iterate – Don’t settle for the first answer. Ask follow‑up questions or request more detail. Claude keeps track of context, allowing a coherent back‑and‑forth.

• Use lists and tables – Ask Claude to present information in lists or tables to improve clarity.

• Polite prompts – A friendly tone often encourages better cooperation. Try beginning your request with “Please” or “Let’s…”.

• Feedback – If Claude’s answer isn’t useful, rephrase your question or use the thumbs down/up icons (available on the interface) to guide future improvements.

Your Turn: Upload a short report or article (PDF) and ask Claude to list five key takeaways. Then ask for an executive summary of the same document.

Write with Claude

Claude excels at generating and editing written content—from blog posts and newsletters to creative fiction and legal documents. Here’s how to harness it for your writing tasks.

Brainstorming & Outlining

Before writing, use Claude to brainstorm topics and structure your piece. For example:

1. Idea generation – Ask: “Generate 10 blog post ideas about sustainable travel targeting digital nomads.” Claude will propose topics, angles and even titles.

2. Outline creation – Try: “Create a detailed outline for a 1,500‑word article about remote team management, including introduction, main points and conclusion.” Claude will organize your ideas into a clear structure.

3. Research support – Upload notes or links and ask Claude to compile relevant statistics or quotes. Claude can process documents up to 30 MB each, up to 20 per chat, so you can feed it whitepapers, reports or transcripts.

Pro Tip: When generating ideas, specify your target audience, desired tone and required length. Specific prompts produce more tailored results.

Drafting Content

Claude can write articles, essays, emails or social media posts. Use the following workflow:

1. Set the context – Describe your goal (“Write a friendly newsletter introducing our new product line”). Include any key points or messaging guidelines.

2. Provide structure – Request a specific format: bullet points, sections or storytelling style.

3. Iterate and refine – If the initial draft isn’t quite right, ask Claude to revise. For example: “Shorten the introduction,” “Make the tone more conversational,” or “Add data from the attached report.”

Sample prompts from AI Writing School’s guidelines include:

• “Generate 10 catchy headline options for a blog post about [topic], incorporating the keyword ‘[your keyword]’”.

• “Analyze this blog post: [paste content] and suggest 3 ways to improve its SEO and readability”.

• “Rewrite this paragraph to improve engagement and naturally incorporate the keyword ‘[your keyword]’”.

These prompts not only help you generate content but also optimize it for SEO.

Editing & Polishing

Claude can serve as your editor:

• Proofreading – Ask Claude to identify grammar and spelling errors in your text.

• Style refinement – Request rewrites in different tones (e.g., professional, persuasive, humorous).

• Summarization – Provide a long document and ask for a concise summary or bulleted key points.

• Translation – Claude supports multiple languages and can help translate or localize your content.

Shortcut: Use Claude’s Artifacts feature (available in Pro/Team plans) to generate documents that appear in a separate window. You can then download or share those artifacts with colleagues.

Creative Writing

For fiction or creative content, use imaginative prompts:

• “Write a 500‑word short story about a time‑travelling botanist discovering a futuristic garden.”

• “Compose a song chorus inspired by monsoon season in Pune.”

• “Continue this story outline: [provide outline].”

In creative writing, iterate with Claude to explore character development, plot twists and alternative endings.

Your Turn: Pick one of your favorite prompts from above and ask Claude to write a first draft. Then challenge Claude to refine the tone or expand on a specific section.

Code with Claude Code

Claude Code is Anthropic’s agentic coding tool that runs in your terminal. It leverages Claude’s reasoning abilities to explore your codebase, write new code, debug issues and manage Git—using natural language commands. It’s available on paid individual plans (Pro and Max) and is separate from the Team plan.

What Makes Claude Code Unique

• Agentic assistant – It operates like a junior developer. Claude Code maps your project, breaks tasks into a to‑do list and explains its reasoning.

• Deep codebase awareness – After exploring your project, Claude Code understands dependencies and architecture.

• Terminal integration – It works in your local shell, so you can run commands, install packages and manage Git.

• Structured problem solving – Claude Code displays its plan, making it easy to follow along and adjust.

Installing Claude Code

To get started:

1. Prerequisites – You need Node.js 18 or higher and, on Windows, WSL2. Install Node from the official website.

2. Install – Run npm install -g @anthropic-ai/claude-code in your terminal.

3. Launch – Type claude to start. Use arrow keys to select your login method and authenticate through your browser.

4. Authenticate – Choose whether to use Claude Code with Pro, Max or via API.

Watch Out! Claude Code currently doesn’t run natively on Windows; WSL2 is required. Make sure you have a Linux subsystem configured.

Starting a Project

1. Create or select a project directory – Claude Code needs a folder where your code lives.

2. Initialize – Use the /init command to generate a CLAUDE.md file summarizing your project’s architecture. This file becomes the memory context for Claude Code—it automatically references it when you interact with the project.

3. Explore the project – Ask Claude Code questions like “Explain this project’s architecture” or “What tests exist in this repo?”.

4. Perform tasks – Request changes such as adding a feature, fixing a bug or refactoring a module. Claude Code will create a plan, implement the changes and show a diff before applying them.

Pro Tip: Use git clone <repoURL> followed by cd <my-project> and then claude to let Claude Code explore a remote codebase.

Agents & claude.md

Users on forums often ask whether they need to explicitly tell Claude to read the claude.md file or where to place agent prompts. The /init command automatically creates and references CLAUDE.md; you don’t need to manually instruct Claude to read it. To extend functionality, you can write additional instructions or agent prompts in this file—Claude Code will follow them by default. Advanced users can design agents to test, deploy or generate documentation; these are beyond the scope of this beginner guide but are great areas to explore once you’re comfortable.

Debugging & Testing

Claude Code can help debug errors and improve code quality:

• Error explanation – Paste an error message and ask Claude to explain the cause and propose fixes.

• Unit testing – Ask: “Write unit tests for the parseDate function in utils.js using Jest.” Claude will generate test files and update your code accordingly.

• Documentation – Request a detailed README or inline comments for a complex module. Claude Code can generate documentation and update the CLAUDE.md file.

Your Turn: Install Claude Code and initialize a new project. Ask Claude to describe your project’s file structure, then request that it write a simple function and generate a unit test. Observe how it plans and executes each step.

Collaborate & Share

Claude isn’t just for individual work—it’s a collaborative assistant. Let’s explore features that help you work with teammates and share your work.

Projects & Knowledge Bases

Projects let Pro and Team users group chats, documents and instructions around a topic. Each project has its own context and 200 k‑token window, so Claude can ground its responses in your internal knowledge—style guides, codebases or interview transcripts. You can also define custom instructions for each project (e.g., “Use a formal tone” or “Answer as a marketing strategist”).

Artifacts

Artifacts are interactive documents, code snippets, diagrams or dashboards that appear alongside your chat. You can:

• View and edit the artifact as Claude generates it.

• Share publicly or within your team, depending on your plan. Free, Pro and Max users can publish artifacts for anyone to view; Team/Enterprise users share internally.

• Customize existing artifacts created by others by clicking Customize; this opens a new Claude chat with the artifact’s content ready for editing.

Sharing Chats & Files

Team users can share snapshots of their best conversations into a project’s activity feed, inspiring colleagues and speeding up onboarding. Artifacts and attachments shared in a project remain within the organization; viewers must authenticate with their team account.

Your Turn: If you have access to Projects, start one for a topic (e.g., “Website Redesign”). Upload your style guide and previous copy, then ask Claude for a brand‑consistent landing‑page draft. Try sharing the resulting artifact with a colleague.

Level Up: Advanced Prompts & Productivity

Once you’re comfortable with the basics, consider these techniques to take your Claude experience to the next level.

Prompt Engineering

• Chain‑of‑Thought – Ask Claude to “show your reasoning” so you can follow its thought process and verify its logic. For example: “List the pros and cons of remote work and explain your reasoning step by step.”

• Role‑playing – Assign Claude a role: “Act as a senior UX designer and critique this interface,” or “You are a legal consultant; draft a contract clause.” This helps tailor responses.

• Constraints & Criteria – Set explicit guidelines: “Write a 400‑word product description using a friendly tone, including three bullet points and a call‑to‑action at the end.”

• System Prompt – For coding tasks or lengthy projects, include a system prompt in claude.md or at the start of your chat detailing Claude’s goals, style and best practices.

Integrations & Automation

• External tools – Although Claude doesn’t browse the internet, you can integrate it with workflow automation tools like Zapier to take actions based on Claude’s outputs. For instance, use a Zap to post Claude’s drafted blog post to WordPress automatically.

• File Analysis – The Analysis Tool (available on some plans) lets Claude extract data from spreadsheets or JSON files. Enable it in your settings to work with XLSX files.

• Multimodal inputs – Recent models can analyze PDFs containing images and charts up to 100 pages long. Use this to interpret slides or reports.

Productivity Hacks

• Templates & Saved Prompts – Create templates for common tasks (e.g., meeting notes, marketing emails) and reuse them. You can store these in Projects or a note‑taking app.

• Keyboard shortcuts – On desktop, use Ctrl/⌘ + Enter to send a message quickly. Star your most important chats to access them faster from the sidebar.

• Collaborative workflows – Use Projects to assign tasks: “@Designer please review Claude’s wireframe artifact,” and track revisions within the same conversation.

Troubleshooting & FAQs

Here are answers to common beginner questions uncovered through user forums and help articles.
