Kotlin Notebook Arrives in IntelliJ IDEA

Starting with version 2025.1, Kotlin Notebook will be integrated into IntelliJ IDEA Ultimate out of the box! Kotlin Notebook is a new interactive environment for JVM developers. The code in the notebooks can even call and use parts of your project codebase, allowing you to experiment with it in an interactive environment. 

Furthermore, Kotlin Notebook is coming to IntelliJ IDEA Community and Android Studio! We heard your feedback, and we want to make Notebook more accessible for everyone.

We are excited to provide you with this powerful tool, which will assist with your everyday needs and even expand Kotlin’s applications.

What can notebooks do? 

Kotlin notebooks are perfect for a wide range of tasks. Here are just a few of the most exciting use cases:

• Prototyping code: You can test your ideas, experiment with code, and build solutions rapidly within an interactive environment, all without needing complex setup or configuration.
• Exploring new APIs and libraries: You can explore new libraries without having to modify your build files, evaluating their features and behavior before integrating them into your project.
• Writing documentation: Not only are notebooks convenient instruments for writing documentation and guidelines that use code snippets, they are great for teaching courses as well.
• In-depth data analysis and visualization: Notebooks are a powerful tool for data visualization, as they allow you to iteratively analyze, visualize, and communicate findings clearly and effectively.
• Exploring HTTP endpoints: You can seamlessly interact with HTTP endpoints directly from notebooks, sending requests and inspecting responses interactively, just as you would with Postman or similar API tools.
• And many more!

We’ll be posting a series of posts about Kotlin Notebook and giving you more interesting details on how you can make the most of it on X and our YouTube channel. Stay tuned to learn more!
