Terms Guardian

Terms Guardian is a web browser extension designed to empower users by demystifying the complex language often found in Terms of Service (ToS) agreements. It automatically detects ToS text on websites, grades its readability, summarizes its content into plain language, and assesses the rights retained or surrendered.

Features

• ToS Detection: Automatically detects when you're viewing a Terms of Service agreement.
• Summary Generation: Provides a concise summary of the ToS in plain language.
• Readability Grade: Grades the ToS text for language complexity using one readability algorithm (Flesch-Kincaid Readability).
• Rights Retention Grade: Grades the ToS based on how much freedom or rights are retained or taken, using a sophisticated TensorFlow.js language model.
• Enhanced Readability Grading: Utilizes additional algorithms (Dale-Chall Readability and Gunning Fog Index) for a more comprehensive language difficulty assessment.
• Uncommon Word Definitions: Provides definitions for uncommon words or excerpts that significantly contribute to the grades.

Additional Functionality

• Detects and highlights legal agreements on web pages
• Extracts relevant legal text for easy reading
• Opens a side panel with detailed information when activated
