Kotlin Notebooks in IntelliJ IDEA: A Comprehensive Guide
If you're a Kotlin developer looking to explore data analysis, machine learning, or just want to experiment with code snippets, Kotlin notebooks in IntelliJ IDEA might be just what you need. This guide will walk you through the process of setting up and using Kotlin notebooks in IntelliJ IDEA, ensuring you make the most of this powerful feature.
What are Kotlin Notebooks?
Kotlin notebooks are a recent addition to the IntelliJ IDEA ecosystem, inspired by popular data science notebooks like Jupyter Notebooks. They allow you to run Kotlin code in a document that supports code, output, and markdown cells. This makes it an ideal tool for prototyping, data analysis, and interactive learning.
Setting Up Kotlin Notebooks in IntelliJ IDEA
Before you start using Kotlin notebooks, you need to ensure you have the latest version of IntelliJ IDEA installed. Once you're up-to-date, follow these steps to set up Kotlin notebooks:

- Open IntelliJ IDEA and click on Preferences (or Settings on Windows).
- Navigate to Plugins and search for Kotlin Notebook.
- Click Install to add the plugin to your IDE.
- Restart IntelliJ IDEA for the changes to take effect.
Creating and Running Kotlin Notebooks
Now that you have the Kotlin Notebook plugin installed, you can start creating and running notebooks. Here's how:
- Open IntelliJ IDEA and click on File > New > Kotlin Notebook.
- Give your notebook a name and choose a location to save it.
- You'll see a new document with a mix of code and markdown cells. You can add, remove, or modify these cells as needed.
- To run a cell, select it and press Shift + Enter. The output will appear below the cell.
Kotlin Notebooks vs. Regular Kotlin Files
You might be wondering why you should use Kotlin notebooks over regular Kotlin files. Here are a few reasons:
- Interactive Learning: Notebooks allow you to run code snippets, see the output, and iterate quickly, making them perfect for learning and experimenting.
- Documentation: You can mix code with markdown, allowing you to document your thought process and results directly in the notebook.
- Data Analysis: Notebooks support data visualization libraries like Bokeh, making them a great tool for data analysis and exploration.
Tips and Tricks for Using Kotlin Notebooks
Here are some tips to help you get the most out of Kotlin notebooks:

- Use markdown cells to explain your code, document your results, or add headings and subheadings to your notebook.
- You can run multiple cells at once by selecting them and pressing Shift + Enter.
- To clear the output of a cell, right-click on the cell and select Clear Output.
- You can export your notebook as a PDF, HTML, or a markdown file by clicking on the three dots in the toolbar and selecting Export.
Conclusion
Kotlin notebooks in IntelliJ IDEA are a powerful tool for Kotlin developers looking to explore data analysis, machine learning, or just want to experiment with code snippets. With this guide, you should now be well-equipped to start using Kotlin notebooks and make the most of this feature.
