Cursor is an AI-powered IDE built on top of VS Code that can generate complete code from natural language prompts, automatically fix errors, and optimize existing code. The demo shows how a simple prompt can create a fully functional React navbar with Tailwind CSS in under a minute, showcasing how AI-native development tools are changing the coding workflow.
Cursor is presented as an AI-powered IDE that builds upon VS Code, bringing AI capabilities directly into the development environment. Unlike using separate AI tools alongside your editor, Cursor integrates the AI agent into the core editing experience.
To use Cursor, you need to download the IDE and create an account on the Cursor website. Once set up, the AI agent becomes available through keyboard shortcuts (Ctrl+K) or the icon in the interface.
The video demonstrates starting with an empty React project and asking Cursor to "generate responsive navbar using React with Tailwind CSS." The AI:
"A complete app has been built just in a minute. This is the power of AI and the Cursor IDE."
When encountering bugs or errors in code, you can select the problematic section, press Ctrl+K, and ask "what is the problem here?" The AI identifies issues (like misspelled function names) and automatically corrects them.
For existing code that needs improvement, simply select it and ask the AI to "optimize." The demonstration shows a simple addition function being refactored, with Cursor displaying both the original and optimized versions for comparison.
"Even if the code is not optimized, it will just optimize code for you."
"It is an amazing IDE. If you want AI powered IDE, just use Cursor."
"What it will do - it will just look to your app first of all, which files are there inside your project, then it will automatically generate the code."
"It will fix the codes for you wherever the error is."
