A media-literacy Chrome extension that grades press articles for bias, tone and sourcing
Each article is graded across ten+ dimensions including political bias, emotional polarity, language complexity and clickbait intensity instead of a single true/false verdict.
The extension evaluates source reliability, citation and referencing quality, statistical relevance and source diversity to expose thin or one-sided reporting.
Click the toolbar icon on any press article and results arrive in seconds with a score and short explanation for every criterion.
Scores for language neutrality and political nuance help distinguish measured reporting from emotionally loaded or one-sided framing.
