What is PrivacyDiff?
PrivacyDiff is a secure online text and code comparison tool designed with privacy as its core principle. Unlike traditional online diff tools that send user data to backend servers, PrivacyDiff operates entirely client-side using JavaScript in the local browser. This approach ensures that all text comparisons are performed directly on the user's device, with no data transmitted over the internet to external servers or third parties.
The tool utilizes the powerful jsdiff library to execute comparisons locally, making it ideal for handling sensitive documents, source code, legal contracts, and private notes without security concerns. Users can compare plain text, rich text, and source code with options for word or character-level precision, and export results while maintaining full confidentiality throughout the process.
