Claude Code is an AI helper that works inside your software project

Claude Code is an AI helper from Anthropic that works inside your software project instead of in a chat window. It can look through your files, change code, run tests and check its own work. It is not free. Using it requires a paid Claude plan, such as Pro or Max, according to a new explainer from Coursera.

What it does

Most AI chat tools only see what you paste in. Claude Code has access to your local project, so it can see how files relate to one another and work across several of them at once. It can also run commands and tests, then use the results to confirm a change works before it calls the task done.

• Read a codebase and find the files tied to a bug or feature
• Edit code across multiple files and keep changes consistent
• Explain what a piece of code does in plain language
• Create Git branches and write commit messages
• Trace bugs, read error messages and run test suites

Git is a system that tracks changes to code. A terminal is a text window where developers type commands. An IDE is the app where many developers write code. Claude Code works in a terminal, an IDE or a browser.

Extra tools for bigger jobs

The article also lists features for organizing larger projects. Hooks run actions automatically at set points, such as running tests after a code change. Subagents hand parts of a project to separate AI agents that work at the same time and report back. Background tasks let long jobs keep running while Claude Code works on something else.

What it costs

There is no separate Claude Code subscription. Access is tied to your Anthropic plan, and your usage costs shift depending on which Claude model you choose. The article does not give plan prices. It warns that Anthropic updates plans, pricing and usage limits over time, so check the latest details before you subscribe or build a workflow around the tool.

Who it is for

The article says it suits people who regularly write, review or maintain code. That includes software developers working on large applications, students who want help understanding or debugging code, and members of engineering teams who share code through Git.

If you mostly write emails, brainstorm, summarize documents or ask general questions, the regular Claude chatbot is a better fit. Both use the same underlying Claude models but are built for different work.

What business owners should know

If you pay developers or build software, a tool like this could save time on routine work. The article does not measure any savings, so treat that as a possibility, not a promise. It also compares Claude Code with GitHub Copilot and ChatGPT. Claude Code is aimed at multi-step tasks it can carry out on its own, while Copilot suits people who want help that appears as they write in their IDE.
