## What it is
Pluto.jl is a reactive notebook environment for the Julia programming language, where cells automatically re-run when their dependencies change. Notebooks are saved as pure Julia files with built-in package management, making them reproducible and easy to share, with a strong focus on education and interactive exploration.

## Use cases
- run reactive julia notebooks in the browser
- teach a scientific computing course with interactive notebooks
- explore models with sliders and widgets bound to variables
- share reproducible julia notebooks with automatic package management
- export notebooks as html or pdf reports
- prototype julia code without hidden workspace state

## When to choose
- you work in Julia and want reactive, reproducible notebooks
- you teach programming or scientific courses and need beginner-friendly interactivity
- you want notebooks saved as plain Julia files with built-in package environments
- you need automatic re-execution of dependent cells like a spreadsheet

## When to avoid
- you primarily use Python or R (use Jupyter instead)
- you need a non-reactive, traditional cell-by-cell execution model
- you need multi-language notebook support
- you require a global switch to disable reactivity
