TrustLayer

About

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
