What Claude Code does

  • Builds features and fixes bugs across several files, not just the one in front of you.
  • Automates development tasks, from a single fix to what Anthropic’s page calls a multi-day migration.
  • Runs in the terminal, in VS Code and JetBrains, in a desktop app and on the web, with more ways listed on its product page.
  • Lets you steer and review the work from where you already are, such as your terminal or IDE.

What people use it for

  • Fix a bug

    Hand it a bug report. Anthropic’s page includes an example in which it traces a duplicate-charge bug to its cause and fixes it.

  • Work across a codebase

    Anthropic describes it as working across multiple files and tools, so it suits changes that touch several parts of a project.

  • Automate repeat development work

    Anthropic’s documentation describes it as able to automate development tasks.

Who it suits

  • Developers comfortable reviewing changes who want an assistant that can act on a whole project.
  • Teams that want one tool across terminal, IDE and web.
