Unlocking Cursor: Your Beginner's Guide to the AI-Powered IDE
Welcome to our opening article about Cursor (AI IDE)! In this article, we would cover all the basic and core knowledge that you need to know about it. And which you would be using most of the time. We’ll do it in depth, without cutting any corners! And in future articles, we'll get into even more complex topics, like advanced tips or Cursor’s “Composer” feature. But first, we’ll start from building a really solid background. So, let's jump right in to it! Nowadays, tech grows and moves so fast that sometimes it's hard to keep up. To stay on top, we as the developers, always have to be ready embrace new tools, which can increase our productivity 10X while saving us a lot of time. One of such tools is Cursor, an IDE powered by AI that’s transforming how developers write, debug, and optimize their code. Cursor combines artificial intelligence with the standard features of an IDE to help you easily debug your code, provide smart code autocompletion, and offer many other features that can boost your productivity. Cursor is forked/built from VSCode, one of the most popular IDEs among developers. And it retains not only the familiar user-friendly interface, but large ecosystem of VS Code extensions as well. This foundation means that those already familiar with VSCode will find it relatively easy to transition to Cursor.
