Claude On PC
Mastery Guide

What Is Claude?

Claude is an AI assistant built by Anthropic. Think of it as an extremely capable digital colleague that can read documents, write content, analyze data, answer questions, and automate tasks on your computer. Unlike a simple chatbot, Claude can work with your files, connect to your apps (Gmail, Slack, Google Drive, and 35+ more), and even execute multi-step tasks while you step away.

The Claude Ecosystem

Claude is not a single tool — it is an ecosystem of interconnected features. Understanding how they fit together is the first step to mastery.

System Requirements

Installing Claude Desktop

Navigating the Interface

The Claude Desktop app has a clean, simple layout. Here is what you will see:

Choosing a Plan

What Is Claude Chat?

Claude Chat is the conversational interface — the "front door" to Claude. You type messages, Claude responds. But it is far more powerful than a simple chatbot. Claude can analyze documents you upload, generate code and interactive applications (called Artifacts), remember your preferences across sessions (Memory), and pull live data from 38+ connected apps (Connectors).

Choosing the Right Model

Claude offers multiple AI models, each optimized for different tasks. You can switch models at any time using the model selector at the top of the chat area.

Your First Conversation

I'm new to using AI assistants. Can you explain what you can help me with on my Windows PC? Give me 5 practical examples I can try right now.

That's helpful. Let's try the first one — can you help me draft a professional email to my team about our Monday meeting?

Artifacts: Interactive Outputs

Artifacts are one of Claude's most powerful features. When Claude generates code, documents, diagrams, or interactive applications, it creates them as Artifacts — standalone, downloadable, and sometimes interactive outputs that appear in a panel next to the conversation.

Projects: Organized Workspaces

Projects let you organize your Claude conversations around specific topics or goals. Each Project can have its own custom instructions and knowledge files, so Claude understands the context without you repeating yourself every time.

You are helping me manage my Q2 marketing campaign. Our target audience is small business owners aged 30-50. Our brand voice is professional but friendly. Always suggest data-driven approaches.

Memory: Claude Remembers You

Memory allows Claude to remember facts about you across conversations. When you tell Claude your name, job title, preferences, or working style, it can store these and apply them automatically in future chats.

Styles: Controlling Claude's Voice

Styles let you control how Claude communicates. Instead of asking "be more concise" in every conversation, you can set a Style that applies globally or per-conversation.

Extended Thinking

Extended Thinking gives Claude extra time to reason through complex problems before responding. When enabled, Claude will show a "thinking" phase where it works through the problem step by step, then delivers a more thorough answer.

Connectors: Linking Your Apps

Connectors let Claude pull live data from your existing apps — email, calendar, documents, project management tools, and more. Once connected, you can ask Claude questions about your real data without manually copying anything.

Summarize my top 10 unread emails and flag any that seem urgent.

What meetings do I have tomorrow? Create a prep doc for each one.

What Is CoWork?

CoWork is where Claude goes from "chatbot" to "virtual assistant." While Chat is conversational, CoWork is task-oriented. You point Claude at a folder on your computer, describe what you need done, and Claude creates a plan, executes it, and delivers results — all within a sandboxed virtual machine for safety.

Your First CoWork Session

Organize all the files in this folder by type. Create subfolders for Documents, Images, Spreadsheets, and Other. Move each file into the appropriate subfolder. Create a summary.txt listing what was moved where.

The 30-Minute Power Setup

The difference between a casual user and a power user is context. By spending 30 minutes creating a workspace structure and context files, you will dramatically improve Claude's output quality for every future task.

C:\Users\YourName\Claude-Workspace\
├── context\          ← Files that teach Claude about you
│   ├── about-me.md
│   ├── brand-voice.md
│   └── working-preferences.md
├── projects\         ← Task-specific folders
│   ├── marketing\
│   ├── finance\
│   └── personal\
└── outputs\          ← Where Claude saves results

Skills: Teaching Claude Your Workflows

Skills are reusable instruction sets that teach Claude how to perform specific tasks. Think of them as "recipes" — instead of explaining your email triage process every time, you create a Skill once and invoke it with a single command.

# Email Triage Skill

## Trigger
When I say "triage my email" or "email briefing"

## Steps
1. Connect to Gmail and fetch the 20 most recent unread emails
2. Categorize each email as: Urgent, Action Required, FYI, or Spam
3. Create a summary table with: Sender, Subject, Category, Suggested Action
4. Draft responses for any "Urgent" emails using my brand voice
5. Save the summary as email-triage-[date].md in my outputs folder

## Output Format
Use a markdown table. Bold the "Urgent" category rows.

Plugins: Bundled Toolkits

Plugins are bundles of skills, connectors, and commands packaged together for specific use cases. They were introduced in February 2026 and are available through the Plugin Marketplace. Think of plugins as "skill packs" — instead of installing 5 individual skills for marketing, you install one Marketing Plugin.

Sub-Agents: Parallel Processing

When Claude encounters a task that can be broken into independent pieces, it can spawn sub-agents — parallel workers that each handle a portion of the work simultaneously. You do not need to configure this; Claude decides when to use sub-agents automatically.

Global Instructions

Global Instructions are rules that apply to every Claude interaction — Chat and CoWork. They are set once and persist across all sessions.

- Always ask clarifying questions before starting complex tasks
- Use American English spelling
- When creating files, use descriptive names with dates (e.g., report-2026-03-25.md)
- Never delete files without explicit confirmation
- Include sources and citations when making factual claims
- Format all currency as USD with two decimal places

Email Automation

Email is one of the highest-impact areas for Claude automation. With the Gmail or Outlook connector, Claude can read, categorize, summarize, and draft responses — saving you hours each week.

Good morning. Please give me my email briefing:
1. Summarize my top 15 unread emails in a table (Sender, Subject, Priority, Summary)
2. Flag anything that needs a response today
3. Draft quick replies for the 3 most urgent emails
4. List any emails I can safely archive

Analyze my inbox from the last 24 hours. Categorize each email:
- 🔴 URGENT: Needs response within 2 hours
- 🟡 ACTION: Needs response this week
- 🟢 FYI: Read-only, no response needed
- ⚪ ARCHIVE: Newsletters, promotions, automated notifications

Save the results as email-triage-[today's date].md

For each email marked URGENT or ACTION, draft a response that:
- Acknowledges their message
- Addresses their specific question or request
- Proposes a next step or timeline
- Uses my professional but friendly tone
- Keeps the response under 150 words

File Organization

Organize my Downloads folder:
1. Create subfolders: Documents, Images, Installers, Spreadsheets, Archives, Other
2. Move each file into the appropriate subfolder based on file type
3. For files older than 30 days, move to an "Archive" subfolder
4. Delete any duplicate files (keep the newest version)
5. Create a cleanup-report.md summarizing what was moved and deleted

Expense & Finance Tracking

Process all receipt files in this folder:
1. Extract: Date, Vendor, Amount, Category (Food, Transport, Office, etc.)
2. Create an expenses.xlsx spreadsheet with these columns
3. Add a "Total" row at the bottom
4. Sort by date (newest first)
5. Flag any receipts over $100 for review

Meeting & Calendar Management

Check my calendar for tomorrow's meetings. For each meeting:
1. List the attendees and their roles (if known)
2. Summarize any recent email threads with those attendees
3. Create a one-page prep doc with: Meeting purpose, Key discussion points, Questions to ask, Action items from last meeting
4. Save each prep doc as meeting-prep-[meeting-name]-[date].md

Research & Document Synthesis

Analyze all documents in this folder. These are competitor reports.
1. Create a comparison matrix: Company, Revenue, Market Share, Key Products, Strengths, Weaknesses
2. Identify the top 3 trends across all reports
3. Write a 500-word executive summary of the competitive landscape
4. Save everything as competitive-analysis-[date].xlsx and summary-[date].md

Presentation Building

What Is Dispatch?

Dispatch (launched March 18, 2026) lets you send tasks to your Windows PC from your phone using the Claude mobile app. You type a request on your phone, and Claude executes it on your desktop — accessing your files, connectors, and skills. It is like having a remote assistant that can operate your computer while you are away.

Setting Up Dispatch

Find the file called "meeting-notes.docx" on my desktop and summarize the key action items.

Tips & Real-World Workflows

What Are Scheduled Tasks?

Scheduled Tasks let you set up recurring automation that runs at specific times — daily, weekly, or on a custom schedule. Instead of manually asking Claude to triage your email every morning, you schedule it once and it runs automatically.

Setting Up Schedules

/schedule Every weekday at 8:00 AM, run my email triage skill and save the results to my outputs folder.

Real Scheduling Use Cases

What Is Computer Use?

Computer Use is Claude's most advanced capability. When enabled, Claude can see your screen, move your mouse, type on your keyboard, and interact with any application — just like a human sitting at your computer. It can fill out forms, navigate websites, switch between apps, and complete multi-step workflows that span multiple applications.

Preparing for Windows Computer Use

While you wait for Windows support, here is how to prepare:

Prompt Engineering for CoWork

The quality of Claude's output is directly proportional to the quality of your input. Here are the principles that separate beginners from power users:

Context Engineering

Context engineering is the practice of systematically providing Claude with the right information at the right time. Your context files (about-me.md, brand-voice.md, working-preferences.md) are the foundation, but advanced users go further.

Global context:     ~/Claude-Workspace/context/about-me.md
Project context:    ~/Claude-Workspace/projects/marketing/context.md
Task context:       Provided in the prompt itself

Multi-Project Management

Power users run multiple Projects simultaneously, each with its own context, connectors, and skills. The key is isolation — each Project should have clear boundaries so Claude does not mix context between them.

Security Best Practices

Pricing & Usage Optimization

Claude usage is metered. Understanding how to optimize your usage helps you stay within your plan limits and get the most value.
