Cursor: An AI-First Code Editor

Cursor looks like VS Code (because it's built from it) but every feature has AI inside. Tab completes whole functions, Cmd+K rewrites code from a description, and chat knows your whole codebase.

Some examples

• Press Tab — Cursor predicts the next 5 lines of code based on context.
• Hit Cmd+K, type 'add error handling,' and watch your function get wrapped in try/catch.
• Open chat and ask: 'Where is the user logged in across this codebase?'
• Use 'composer' to make multi-file changes from one prompt.

Try it!

Download Cursor (free tier exists). Open one of your projects. Try Tab completion on a function and Cmd+K to rewrite something. Compare to your normal flow.

Practice this safely

Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.

1. 1Ask AI to explain code completion in plain language, then underline anything that sounds uncertain or too broad.
2. 2Give it one detail from "Cursor: An AI-First Code Editor" and ask for two possible next steps plus one reason each step might be wrong.
3. 3Check Cursor against a trusted source, teacher, adult, expert, or original document before you use it.
