What is Juno?
Juno is an AI-powered coding companion designed specifically for data scientists working in Jupyter notebooks. It integrates seamlessly with your existing workflow to automate code writing, editing, and debugging through simple magic commands. Juno does the work of coding up whatever you ask for – from complex PCA (Principal Component Analysis) to creative visualizations like drawing a unicorn – by using the %juno command to get code suggestions on the fly.
Key features include real-time code generation via the %juno magic command, an auto-debugging feature with a dedicated Debug button that provides instant solutions to any error, and an AI-powered Edit Button that acts like having an AI pair programmer to refine, optimize, or completely rewrite code based on your data and problem context. Juno understands your notebook context and can answer questions about your data while helping you spend more time analyzing data instead of fighting NaN errors and Matplotlib API issues.
Juno is built with privacy as a core principle – it only uses metadata about your datasets and never exposes raw data rows or personally identifiable information (PII). For extremely privacy-sensitive datasets, users can run Juno on their own servers through an on-premises deployment option. The tool is suitable for data scientists, analysts, software engineers, students learning data science, and any professionals who work with Jupyter notebooks for data analysis, machine learning prototyping, and data visualization.
The tool works across major platforms including Windows, Mac, and Linux, supports Python 3.6 and above, and offers comprehensive support through email assistance and detailed documentation. Juno accelerates coding workflows, reduces debugging time, improves code quality, and enables rapid prototyping of machine learning models.
Juno pricing
Pricing model: Free
Juno offers 40 free prompts to start. After the free prompts, the subscription is $4.99/month. The pricing model is simple and straightforward for individual data scientists.

Frequently asked questions about Juno
What is Juno?
Juno is an AI-powered coding companion designed for data scientists working in Jupyter notebooks. It automates code writing, editing, and debugging through the %juno magic command, providing real-time code suggestions for tasks ranging from PCA analysis to data visualizations.
How do I install Juno?
Install Juno using pip by running the command: pip install juno-ai. You can also install it directly from your Jupyter notebook using %pip install juno-ai, then load the extension with %load_ext juno at the top of your notebook.
How many free prompts are available?
Users get 40 prompts free before requiring a subscription. After using all 40 free prompts, you need to subscribe at $4.99/month to continue using Juno.
How does Juno protect data privacy?
Juno only processes metadata about datasets and never exposes raw data rows or personally identifiable information (PII). For extremely sensitive data, users can opt for on-premises deployment on their own servers to maintain complete control over their data.
How does the Debug button work?
When you encounter an exception or error in your Jupyter notebook, a Debug button appears. Clicking it makes Juno analyze the error and provide an instant solution in a new cell, significantly reducing troubleshooting time and helping you focus on data analysis instead.
What is the Edit Button feature?
The Edit Button works like an AI pair programmer. You click the ✎ button, add a prompt after %edit text, and run the cell. Juno can refine, optimize, or completely rewrite your code based on your data and problem context to enhance performance and readability.
How do I use the %juno command?
Run %juno followed by your prompt in a cell to get code suggestions. For example, '%juno perform PCA analysis on my dataset' or '%juno draw a unicorn'. Juno will generate the full code cell based on your description.
What is PCA analysis and how does Juno implement it?
PCA (Principal Component Analysis) is a statistical technique for dimensionality reduction in data. Juno enhances data analysis by employing AI-driven PCA to automatically generate the code for performing PCA on your dataset, facilitating better data insights and visualization.
Who can benefit from using Juno?
Juno is designed primarily for data scientists and analysts working in Jupyter notebooks. It also benefits software engineers, students learning data science, researchers prototyping machine learning models, and anyone who needs efficient coding, debugging, and data analysis tools.
Can I use Juno with sensitive enterprise data?
Yes, Juno Enterprise offers a self-hosted on-premises deployment option for organizations with strict data governance requirements. This allows you to run Juno on your own servers while maintaining complete control over your confidential data, as Juno never exposes raw data rows or PII by default.
