The Tools

Three tools. One goal. Different vibes.

Your AI Coding Toolkit
01 Claude Code Terminal-native. Full system access.
→
02 Cursor IDE with AI built in. Visual + powerful.
→
03 Replit Browser-based. Zero setup. Instant preview.
Power ←→ Ease. Pick the tool that matches your comfort level.

Not all AI coding tools work the same way. Some live in your browser. Some live in a code editor. Some run in your terminal. The right choice depends on what you are building, how much coding experience you have, and how you like to work.

Here is the honest breakdown — no hype, just what each tool actually does well.

CLAUDE
Claude Code (Terminal-based)
Anthropic's CLI coding agent. You describe what you want in your terminal and Claude reads your files, writes code, runs commands, and builds features autonomously. Best for: people comfortable with a terminal, full-stack projects, serious app building. Power level: very high.
CURSOR
Cursor (Editor-based)
A code editor with AI built in. You see your files, highlight code, and chat with AI about changes. Best for: people who want to see and understand the code as it is written. Visual learners. Developers leveling up with AI. Power level: high.
REPLIT
Replit (Browser-based)
Everything in your browser. No installation. Describe what you want, Replit builds it, and you can deploy with one click. Best for: absolute beginners, quick prototypes, people who do not want to install anything. Power level: medium-high.
Decision Time

Which one should you pick?

Do not overthink this. Pick the one that matches where you are right now. You can always switch later.

Pick Your Tool

I have never written a line of code. I want to start building TODAY. I do not want to install anything.
Start with Replit. Open replit.com in your browser, describe what you want to build, and watch it appear. Zero setup. Zero installation. You can always graduate to more powerful tools later.
I am curious about code. I want to see what AI is writing. I want to learn while I build.
Start with Cursor. Cursor shows you the code as AI writes it. You can ask questions about any line. It is the best tool for people who want to understand what is happening under the hood while still moving fast.
I have some technical comfort. I want maximum power. I am building something serious.
Start with Claude Code. Claude Code is the most autonomous option. It reads your entire project, makes changes across multiple files, runs tests, and handles complex tasks. It is the closest thing to having a developer on your team.
I honestly have no idea. Just tell me what to do.
Start with Replit. Seriously. It is the lowest friction way to experience vibe coding. Build something small. Feel the magic. Then decide if you want more power. You will know when you are ready to level up.
Get Started

Setting up in under 5 minutes.

Each tool has a different setup process. Here is the fastest path to getting started with each one.

Replit (30 seconds)

Go to replit.com. Create a free account. Click "Create Repl." Choose "Agent" mode. Describe your app in the text box. That is literally it. Your app starts building immediately.

Cursor (3 minutes)

Go to cursor.com. Download the app for your computer. Open it. Create a new project folder. Press Cmd+K (Mac) or Ctrl+K (Windows) to open the AI prompt. Describe what you want. Cursor starts writing code in the editor.

Claude Code (5 minutes)

Open your terminal. Run npm install -g @anthropic-ai/claude-code. Navigate to your project folder. Type claude. Start describing what you want to build. Claude reads your project and starts creating files.

Deeper Understanding

The three modes of AI coding.

Understanding the difference between these modes will help you pick the right tool and use it effectively.

CHAT
Chat-based (Replit Agent)
You chat back and forth. AI builds the whole thing. You see the result in a preview window. Most beginner-friendly. Trade-off: less control over individual code decisions.
EDITOR
Editor-based (Cursor)
You see the code files. AI suggests changes inline. You accept, reject, or modify. Best balance of control and speed. Trade-off: requires some comfort with looking at code.
CLI
Terminal-based (Claude Code)
AI operates autonomously across your entire project. Reads files, writes code, runs tests, installs packages. Most powerful. Trade-off: you need to be comfortable with the command line.

The key insight: The tool does not matter as much as starting. Pick one, build something, and learn by doing. You can always switch tools later. What you learn about describing features and reviewing results transfers to any tool.

Review

Key concepts to remember.

AI Coding Tools

What is Claude Code?
A terminal-based AI coding agent from Anthropic. It reads your entire project, writes code across multiple files, and runs commands autonomously. Most powerful option.
What is Cursor?
A code editor with AI built in. You see files and code while AI suggests changes inline. Best for learning while building.
What is Replit?
A browser-based coding platform with AI agent mode. Zero installation. Describe what you want and it builds it. Best for beginners.
What are the three modes of AI coding?
Chat-based (Replit), Editor-based (Cursor), and Terminal-based (Claude Code). Each offers different levels of control and autonomy.
Which tool should a complete beginner choose?
Replit. Zero setup, runs in browser, and you can go from description to working app in minutes.
Can you switch tools later?
Yes. The skills you learn — describing features, reviewing results, iterating — transfer to any AI coding tool.
