## What it is
Linkook is a Python-based OSINT command-line tool that discovers linked social media accounts and associated email addresses across multiple platforms from a single username. It can check discovered emails against breach databases and export relationship data in a Neo4j-compatible JSON format for visual graph analysis.

## Use cases
- find all social media accounts linked to a username
- discover emails associated with a social media handle
- check if an email has been compromised in a data breach
- map a person's online footprint across platforms
- export OSINT scan results to Neo4j for graph analysis
- pentest reconnaissance on a target username
- alternative to Sherlock for username enumeration

## When to choose
- you need to trace interconnected social accounts and emails from one username
- you want breach-check integration (HudsonRock or Have I Been Pwned) built into username enumeration
- you want scan results as a graph database export for visual link analysis
- you prefer a pipx-installable Python CLI for OSINT workflows

## When to avoid
- you need a web GUI or dashboard rather than a command-line tool
- you only need simple username existence checks without linked-account traversal or email discovery
- you require real-time monitoring or scheduled continuous OSINT collection
- your use case is commercial bulk enrichment at scale rather than targeted investigation
