Claude, Claude Code & The IDE — What They Are & How They Fit Together

This video demystifies the key tools we'll be using throughout the course — Claude, Claude Desktop, Claude Code, and the IDE — and explains the differences between them before we go ahead and set everything up.

What is Claude? Claude is a large language model built by Anthropic. Most people think of it as a chat interface where you ask questions and get responses — similar to ChatGPT. But it can also analyse documents, generate images, build websites, write emails, create charts, and function like a human assistant. You can access it through Claude.ai (the web version) or download Claude Desktop (the app).

Claude Desktop: Claude Desktop is designed to be the easy-to-use interface. Beyond chat, you can build artifacts (prototypes, games, brainstorming boards, PRDs), create custom agents, and connect it to external tools via connectors — Gmail, Slack, Figma, Monday.com, CRM systems, accounting software, and more. These connectors are actually MCPs (Model Context Protocols) — essentially bundles of a tool's APIs packaged in a format that's easy for the AI to read and use. Instead of manually setting up each API connection, you just connect the tool and Claude handles the rest behind the scenes.

Claude Code: Claude Code is where the real building power lives. It's the same Claude chat, but accessed through a terminal/command line inside an IDE, giving you more control, developer functionality, and the ability to reference project files directly. If you want to build complex applications, AI operating systems, or anything beyond quick tasks — Claude Code is what you'll use. For simpler things like drafting an email or asking a general question, Claude Desktop is faster and easier.

What is an IDE? IDE stands for Integrated Development Environment. It looks intimidating at first, but it's essentially just a file manager with extra powers — you're looking at folders on your computer, editing files, and running commands. The three major IDEs are VS Code, Cursor, and Windsurf (with Anti-Gravity also gaining traction). We'll use Cursor in this course because it lets you access multiple AI models (Claude, GPT, Gemini) through one interface, though the core principles are the same regardless of which IDE you choose.

When to Use What:

Claude Desktop — quick tasks, planning, general questions, simple automations
Claude Code (in Cursor) — building apps, AI operating systems, complex features, anything requiring file access and developer control
GitHub — essentially Google Drive for code; back up projects, store them online, pull them onto different machines, and collaborate in teams

The Key Takeaway: The IDE looks intimidating for non-developers, but once you spend a couple of hours getting familiar, you'll realise it's not that different from Claude Desktop — just with a few extra controls. Being able to use Claude Code in the IDE is the skill of 2026. Next up, we'll install everything you need to go from nothing to a fully working setup.
