What Is Anthropic?

Anthropic is one of the world's leading AI safety companies, founded in 2021 by former OpenAI researchers, including siblings Dario and Daniela Amodei. Their mission is to build AI that is safe, reliable, and genuinely useful.

Claude is Anthropic's AI. Think of it the same way you'd think of Google and Gemini, or Microsoft and Copilot. Anthropic is the company. Claude is the product. And in 2026, Claude has grown from a single chatbot into a full suite of five distinct tools.

The Claude Product Suite at a Glance
  • Claude Chat Conversational AI, no setup required
  • Claude Code Agentic coding tool for developers
  • Claude Cowork Desktop AI worker for non-technical users
  • Claude in Chrome AI that acts inside your browser
  • Computer Use AI that controls your entire computer

Each tool uses the same underlying Claude AI. The difference is the interface, the permissions, and how deeply Claude gets access to your work. Think of it as a ladder, from a simple conversation all the way to full autonomous control of your machine.

Most people discover Claude Chat, use it like a fancy Google search, and never go further. But the real productivity gains, the ones that are replacing entire job functions, live in Cowork, Code, and Computer Use. This guide exists so you know exactly what each tool does, whether it's relevant to your life, and how to get started.

Tool 02

Claude Chat

Claude Chat is the web-based and mobile chatbot available at claude.ai. You type a message, Claude responds. No installation required. It runs entirely in your browser or on the Claude mobile app. This is Claude at its most accessible, and most people who've heard of Claude have only ever used this version.

Unlike ChatGPT, Claude Chat is known for longer, more nuanced responses and a much larger context window, meaning you can paste in entire documents, long transcripts, or multiple files and Claude will actually read and process all of it. It's also widely regarded as better at tone, writing quality, and following complex instructions.

Accessclaude.ai: browser or mobile app
SetupNone, just sign up
Free tierYes, with usage limits
Paid plansPro ($20/mo), Max ($100–200/mo)
Best forWriting, research, brainstorming, analysis

What it can do

What it cannot do

Claude Chat cannot access your local files, create documents on your computer, take actions on websites, or remember things between separate conversations (unless memory is enabled). Every new chat starts fresh. It talks about work, it doesn't do the work on your machine.

Who it's for

Example Prompt

"I run a small business in New Zealand. Write me a punchy 30-second Instagram caption about why AI is going to change small business forever."

Tool 03

Claude Code

Claude Code is a command-line tool (CLI) that you install directly on your computer. Instead of responding in a chat window, Claude Code reads your actual files, writes real code, runs tests, fixes errors, and makes changes to your project, autonomously. It was released in early 2025 and quickly became the most talked-about AI coding tool among developers worldwide.

The key difference from Chat is execution. Claude Chat tells you how to solve a problem. Claude Code solves the problem in your actual files. You give it a task: "build me a contact form", "fix this bug", "refactor this module", and it reads your entire codebase, understands the architecture, and makes the changes itself. You review and approve. It drives.

AccessTerminal / command line (also VS Code + JetBrains plugins)
SetupInstall via terminal, takes ~10 minutes
Free tierNo, requires paid Claude plan
Paid plansIncluded with Pro ($20/mo) and above
Best forDevelopers, technical builders, vibe coders

What it can do

You don't need to be a software engineer to use Claude Code. You need to be comfortable in a terminal, but that's learnable in an afternoon. The concept of "vibe coding" — describing what you want and letting Claude build it — went viral in early 2026, and Claude Code is the engine behind it.

Example Prompt

"Look at all the files in this folder and rename them so they're organised by date and topic. Then create a README that summarises what's in each file."

Tool 04

Claude Cowork

Claude Cowork is a desktop application, downloaded at claude.com/download, that lives inside the Claude desktop app as a separate tab alongside Chat and Code. Launched in January 2026, it's Anthropic's answer to one question: how do we give non-technical people the same autonomous AI capabilities that developers get with Claude Code, without any terminal or coding required?

The defining feature of Cowork is local folder access. You point Claude at a folder on your computer, give it a task, and it reads across all your files, does multi-step work, and produces real finished outputs (.docx, .xlsx, .pptx) that you can open immediately. It's not generating text in a chat window. It's doing work and leaving behind files.

AccessClaude Desktop app: claude.com/download
SetupDownload app, open Cowork tab, select a folder
Free tierNo, requires paid Claude plan
Paid plansPro ($20/mo) and above
Best forNon-technical knowledge workers, business owners

What it can do

The Mindset Shift

ChatGPT trained you to write better prompts. Cowork is different: the game is folders and files. You give Claude a folder full of context about your business, your writing style, your SOPs, your past work. That folder becomes Claude's briefing. It works like an employee who's read everything you've ever written.

Example Prompt

"Read everything in this folder and write me a one-page business summary I can send to a new client. Save it as a Word document with my branding colours and a professional layout."

Tool 05

Claude in Chrome

Claude in Chrome is a browser extension, installed from the Chrome Web Store, that sits in a sidebar while you browse. Unlike the other Claude tools, this one operates inside your browser in real time. It can see the pages you're looking at and take actions on them: clicking buttons, filling in forms, extracting data, navigating between pages.

Every other tool in the Claude suite works with files or code on your machine. Claude in Chrome works on the live web. It sees what you see and can act on it. This is especially powerful paired with Cowork: Chrome becomes the research layer, gathering and extracting information from websites, while Cowork turns that research into polished finished files.

AccessChrome Web Store, search "Claude"
SetupInstall extension, sign in, grant permissions
Free tierNo, requires paid Claude plan
Paid plansPro (Haiku model), Max/Team/Enterprise (full model choice)
Best forResearch, data extraction, repetitive browser tasks

What it can do

A Note on Safety

Because this extension has access to your browser, Anthropic strongly recommends only granting permissions to familiar websites. Always review before Claude handles financial or sensitive tasks. Some websites contain hidden instructions designed to hijack AI assistants (prompt injection). The extension has defences against this, but staying alert is good practice.

Example Prompt

"Read this competitor's website and pull out their pricing, their top three features, and who their target customer is. Format it as a comparison table."

Tool 06

Computer Use

Computer Use is not a separate app, it's a capability built inside Claude Cowork and Claude Code that launched on March 23, 2026. When enabled, Claude can control your entire Mac: clicking, typing, scrolling, opening apps, navigating your desktop. It's not limited to the browser or your files, it can use any application on your computer, just like a human would.

The wow factor is Dispatch, Anthropic's phone-to-desktop feature. You send Claude a task from your iPhone. Claude works on your Mac while you're away. You come back to finished work. The sequence is: message from phone, Claude opens apps, clicks around your desktop, completes the task, you return to the result. No one sitting at the computer required.

AccessInside Claude Cowork or Claude Code desktop app
SetupEnable in desktop app settings, macOS only (March 2026)
Free tierNo
Paid plansPro ($20/mo) or Max ($100/mo)
StatusResearch preview, still early, some tasks may need retries
Best forAutomating desktop workflows, apps without API connectors

How Claude decides which tool to use

1st: ConnectorsUses Gmail API to read your email directly
2nd: ChromeOpens browser, navigates to Gmail
3rd: Computer UseClicks around your desktop like a human would
Important Caveats

Computer Use is in research preview. Complex tasks sometimes need a second attempt. Screen-based navigation is slower than a direct API integration. Anthropic strongly recommends not using it with banking, healthcare, or other sensitive apps at this stage, and to always review Claude's planned actions before approving them.

Example Prompt

"Open Google Chrome, go to Gmail, and draft an email to my team saying our Monday meeting is pushed to 2pm. Use my usual sign-off."

Where Should You Start?

Complete beginner to AI

Start with Claude Chat. Get a free account at claude.ai, ask it something you'd normally Google, and notice the difference. Once you're comfortable, upgrade to Pro and explore Cowork.

Business owner with repetitive admin work

Go straight to Claude Cowork. Download the desktop app, point it at a folder with your business documents, and ask it to produce something: a report, a summary, an email draft. The moment you open a real finished file that Claude created, you'll understand the shift.

Developer or technical builder

Claude Code is your tool. Install it, point it at a project, and give it a task. Start small: fix a bug, write a function, then scale up. The productivity gains compound quickly.

Content creator or researcher

Claude in Chrome paired with Claude Chat is your stack. Use Chrome to gather and extract information from websites, then use Chat or Cowork to turn that research into content.

Power user or early adopter

Enable Computer Use inside Cowork and try Dispatch. Send a task from your phone, step away, and come back to the result. This is the frontier, it's rough around the edges but it's a preview of how most computer work will happen in a few years.

The Bottom Line

Claude isn't one thing. It's a ladder. You don't have to climb all of it at once. Start where you are. Move up when you're ready. The people who understand this entire suite, not just Chat, are the ones building an unfair advantage right now.
