## What it is
nbdime provides tools for diffing and merging Jupyter notebooks, with terminal commands (nbdiff, nbmerge, nbshow) and rich web-based diff/merge views. It integrates with version control systems like git and mercurial as a diff and merge driver.

## Use cases
- diff two jupyter notebooks
- merge conflicting notebook changes from a git branch
- set up git to diff notebooks instead of showing raw JSON
- review notebook changes in a rendered web view
- resolve merge conflicts in ipynb files
- show a notebook in a terminal-friendly format

## When to choose
- you use notebooks in version control and need meaningful diffs
- you need to merge notebooks with conflict resolution
- you want a rendered, cell-level diff rather than raw JSON comparison

## When to avoid
- you need to diff plain text or non-notebook files
- you want a general-purpose git diff tool

## Facets
- artifact type: cli-tool
