About:
Magika is a machine learning-based file type detection tool that leverages deep learning models to accurately identify file content types. Unlike traditional methods that rely on file extensions or magic bytes, Magika analyzes the actual content structure to detect over 100 file types with high precision. This approach is particularly valuable for security applications where accurate file identification is critical.

Key Features:

AI-powered content detection using deep learning models
Supports over 100 file types with high accuracy
Fast inference optimized for production use
Command-line interface for easy integration
Open-source implementation from Google

Use Cases:

Security scanning and malware detection pipelines
File processing workflows requiring accurate type verification
Data loss prevention (DLP) systems
Digital forensics and incident response

Alternatives:

file – Traditional Unix tool using magic bytes; less accurate for ambiguous or disguised files
python-magic – Python wrapper around libmagic; similar to file command but with Python API
trid – Windows-focused file type identifier; uses signature databases rather than ML
