BiasCheck

Bias analyzes any webpage, article, or selected text and tells you exactly how slanted it is — politically, emotionally, and factually — using on-device AI. No accounts. No servers. No data ever leaves your device. HOW IT WORKS Enable Bias in Safari (Settings → Safari → Extensions → Bias). Then tap the Bias icon in Safari's toolbar to analyze the current page. Or long-press any selected text and tap "Check Bias" from the menu. WHAT YOU GET • Political Lean — a left-to-right spectrum showing where the content sits, from Far Left to Far Right • Bias Score — 0–100 neutrality score so you can compare sources at a glance • Truthiness Score — how factually grounded the content appears • Bias Types — Framing Bias, Loaded Language, Appeal to Emotion, Confirmation Bias, and 18 more • Emotional Tone — Neutral, Sensational, Fear-Mongering, Inflammatory, and more • Summary — a plain-English explanation of what bias is present and why • Key Phrases — the exact quotes driving the detected bias COMPLETELY PRIVATE Everything runs on your device using Apple's on-device AI. Your text, history, and settings never touch a server. Deleting the app permanently removes all stored data. SAFARI EXTENSION Bias adds a "Check Bias" option to Safari's long-press menu for any selected text. Results appear instantly in the extension popup without leaving the page you're reading. HISTORY Every analysis is saved locally so you can review and compare past results across sessions. No subscription. No API keys. No accounts. Just clarity.
