## What it is
A Neovim plugin that renders VSCode-style diffs with side-by-side or inline layouts and two-tier line/character-level highlighting, powered by the same C diff algorithm VSCode uses. It also provides git revision comparison, merge conflict resolution, and git history browsing.

## Use cases
- view side-by-side diffs in neovim like vscode
- review git changes with character-level highlighting
- resolve merge conflicts in neovim
- compare files between git commits branches or tags
- browse git history of a file in neovim
- toggle between unified and side-by-side diff layouts

## When to choose
- you want vscode-quality diff rendering inside neovim
- you need fast C-based diff computation with multi-core parallelization
- you want a built-in mergetool and git history viewer for neovim

## When to avoid
- you use an editor other than neovim
- you need a standalone CLI diff tool outside an editor
- you cannot download prebuilt binaries or compile C code
