Q&A

What is Magika by Google designed for?

Magika by Google is designed for detecting and classifying various file content types leveraging the power of deep learning.

How does Magika differ from traditional file type detection tools?

Magika differs from traditional file type detection tools by providing enhanced accuracy across a broad range of content types. It uses deep learning, making it more precise and comprehensive in support.

How can I test out Magika's capabilities?

Users can test out Magika's capabilities directly from their browser. It provides a user interface where files can be dropped for classification.

How does Magika ensure the security of uploaded files?

Security of uploaded files in Magika is ensured by processing them entirely in the user's browser. At no point are the files uploaded to external servers.

Can Magika be installed as a Python package?

Yes, a unique feature of Magika is its availability as a Python package. This feature allows users to run it readily from their command line.

Is Magika compatible with Python and JavaScript codebases?

Absolutely. Magika can be easily integrated into both Python and JavaScript codebases, making it a versatile tool in a developer's kit.

What kind of files can Magika detect and classify?

Magika can detect and classify a broad range of files including language-specific files, executables, document types, image and video data, and audio bitstream data, among others.

Is there a version of Magika being used internally at Google?

Yes, reports indicate that a similar version of Magika is being used internally at Google, capable of scanning millions of files per second for accurate content-type tagging.

When is the detailed paper on Magika's training and performance expected to be released?

The release of a detailed paper explaining how Magika was trained and its performance on large datasets is planned for the near future.

Can Magika output more than one content type for a file?

No, Magika is designed to output a single content type for a file, therefore, it will not map polyglot files to two or more categories.

Where can users find the citation guide for Magika?

Users wanting to cite Magika can find a citation guide available on the project's GitHub page.

How efficient is Magika at detecting and classifying file content?

Magika is designed with a focus on efficiency. Despite offering enhanced accuracy, it operates quickly even on a single CPU.

What are the key features of Magika?

Key features of Magika include its deep learning-based design for superior performance, browser-side processing for security, and its versatile integration with Python and JavaScript. It can be installed as a Python package and it offers comprehensive support for detecting and classifying a broad range of content types.

How accurate is Magika in detecting and classifying files?

Magika achieves an impressive 99%+ average precision and recall, making it highly accurate in detecting and classifying files.

Can Magika operate effectively on a single CPU?

Yes, Magika operates quickly and efficiently even on a single CPU.

Does Magika perform processing browser-side with no uploads to external servers?

Yes, all processing in Magika occurs on the user's browser side with absolutely no uploads to any external servers.

Which content types can Magika detect?

Magika can detect a wide range of content types including language-specific files, executables, document types, image and video data, and audio bitstream data.

What kind of support does Magika offer for language-specific files, executables, and other document types?

Magika offers comprehensive support for various content types. This includes language-specific files, executables, and an array of document types such as Word, PDF, INI, and more.

Is Magika capable of mapping polyglot files to multiple categories?

No, Magika is designed to output a single content type for a file. Therefore, it will not map polyglot files to multiple categories.

How can Magika be leveraged in a developer's toolkit?

Magika can be leveraged in a developer's toolkit by installing it as a Python package for use from the command line and by integrating it into Python or JavaScript codebases.
