TrustLayer

Real-time source credibility scoring, bias detection, and fact-check overlays for every page you visit

You click a link. It looks like news. It has a professional layout. But is it actually credible? Is it pushing a political agenda? Is the article 3 years old being shared as if it just happened? TrustLayer answers those questions in under a second — on every page you visit. What It Does TrustLayer combines a curated media database with a 5-category algorithmic scoring system to give you a real-time credibility assessment of any web page: - Credibility Score (A-F) — Instant letter grade with a 0-100 numeric score. Grades are based on domain reputation or a 5-category weighted algorithm for unknown sources - Political Bias — Detects lean from Far-Left to Far-Right using the Media Bias Fact Check (MBFC) database for known sources - Tone Analysis — Measures sensationalism (%) and clickbait score (%) from article language patterns - Article Age & Freshness — Detects publish date, modified date, and flags articles older than 90 days - Citation & Source Check — Counts how many links in the article body point to reputable sources (.gov, .edu, Reuters, AP, etc.) - Why This Score — Full per-category breakdown (Domain Trust, Editorial Standards, Transparency, Content Quality, Red Flags) with explanations Scoring Categories Domain Trust — TLD quality, HTTPS, domain pattern Editorial Standards — Author, date, citations, structured data Transparency — Correction policy, about/contact, ownership Content Quality — Word count, quotes, structure, sourcing Red Flags — Ads, popups, caps title, clickbait patterns Who It's For - Journalists and researchers verifying sources - Students checking article credibility for assignments - Anyone concerned about misinformation and media bias - Professionals who need to vet sources quickly - Fact-checkers and media literacy educators How It Works 1.
