Master baker tier. Every paragraph earns its place on the tray.
Summary
x-ray is a Python library developed by Free Law Project to detect improperly redacted PDF documents. The tool addresses the common problem where people incorrectly redact sensitive information by simply drawing black rectangles or highlights over text, which can still be selected and read. The project was motivated by years of encountering poorly redacted documents, including one that exposed Taylor Swift's personal phone number.

· 4 pulledx-ray is a Python library for finding bad redactions in PDF documents.
An ongoing problem is that people fail to properly redact things. Instead of doing it the right way, they just draw a black rectangle or a black highlight on top of black text and call it a day.
Well, when that happens you just select the text under the rectangle, and you can read it again. Not great.
After witnessing this problem for years (our favorite is the doc that shared Taylor Swift's personal phone number), we decided it would be good to do something about it.
