What is Juno?

Juno is an AI assistant designed for data scientists and analysts working in Jupyter notebooks. It helps with common coding tasks by offering real-time code suggestions, spotting and fixing bugs, and refining existing code. The tool installs directly into your Jupyter environment via pip, so you can access AI assistance without leaving your notebook. Privacy is central to Juno's design. It processes only metadata rather than your full code, and offers on-premise deployment for teams handling sensitive data. This makes it suitable for both individual data scientists and organisations with strict data governance requirements. You get 40 free prompts to try it out, after which you'll need a paid subscription to continue using the service.

Pros & cons

Advantages

Sits directly in your Jupyter workflow, so no context switching between tools
Privacy-conscious approach means your actual code doesn't leave your environment by default
Simple installation using pip makes getting started quick
On-premise option suits regulated industries and sensitive projects

Limitations

Free tier is limited to 40 prompts, so you'll need to pay for ongoing use
Effectiveness depends on how well the AI understands your specific domain or coding style
