Claude Code

Anthropic's AI coding agent for the terminal. Reads your codebase, edits across files, runs commands.

Lv.3 BuilderAI Coding

In plain English

Like having a senior developer available in your terminal. You describe what you want changed, it reads your entire project, makes edits across files, and runs commands.

Real-world example

You have a Next.js app and say 'add user authentication with Google login and a protected dashboard.' Claude Code reads your codebase, creates the auth pages, sets up the API routes, and wires everything together.

Where this fits in your project

A terminal-based AI agent. Powerful for developers comfortable with the command line.
