## What it is
Projectile is a project interaction library for Emacs that provides project-level navigation, search, and task-running features. It automatically detects projects via VCS repos, build tool markers, or a .projectile file, and works with any completing-read-based completion UI.

## Use cases
- jump to a file in my project quickly
- toggle between code and its test file
- search and replace across an entire project
- switch between recent projects in Emacs
- run build and test tasks for the current project
- work within a subproject of a monorepo
- find references to a symbol in a project

## When to choose
- you use Emacs and want fast project-wide file navigation and search
- you need portable project indexing that works on Windows without external tools
- you want per-project workspaces, sessions, and task running inside Emacs

## When to avoid
- you use a different editor like VS Code or Vim with its own project tooling
- you only need simple single-file editing without project context
- you prefer the built-in project.el and don't need extra features

## Facets
- artifact type: plugin
- maturity: stable
- function: developer-tools, file-system, search-engine, cli
- domain: developer-tools, text-editors
- platform: cross-platform
- tags: emacs-lisp, project-navigation, project-management, melpa, editor-plugin, emacs
