Signal Layer

Analyzes web content for synthetic patterns & SEO templates. 100% local — no data sent, no API, no server.

Signal Layer — Content Signal Analyzer The internet is filling with template-generated content, SEO farms, and AI-expanded articles that are hard to distinguish from genuine human writing. Signal Layer gives you a fast, transparent, privacy-first tool to evaluate what you are actually reading. HOW IT WORKS ──────────── Click the Signal Layer icon on any page. The extension analyzes the visible text entirely within your browser — no data leaves your device, no API is called, no server is contacted. In seconds you receive three outputs: • Human Trace Score (0–100) — A single composite number. Higher scores indicate organically structured text with strong lexical diversity. Lower scores reflect dense template patterns and low linguistic variation. • Synthetic Content Signal (Low / Medium / High) — Evaluates AI-associated transitional phrase density, sentence rhythm uniformity, and vocabulary repetition. • Template Repetition Signal (Low / Medium / High) — Detects repeated trigram clusters, affiliate and commission links, and bullet-heavy structural layouts. A short plain-language explanation accompanies every result. WHAT MAKES SIGNAL LAYER DIFFERENT ────────────────────────────────── Most "AI detector" tools send your text to a remote server and return a black-box percentage. Signal Layer does the opposite: ✓ Zero data collection — nothing is transmitted, stored, or logged ✓ No API dependency — works offline, no OpenAI or Anthropic key required ✓ No percentage claims — scores reflect statistical text patterns, not authorship verdicts ✓ Academic-safe — the scoring model distinguishes formal academic writing from synthetic SEO content, avoiding false positives on structured scholarly text ✓ Transparent affiliate detection — separates genuine commission links (Amazon ref=, ShareASale, Awin) from standard analytics trackers (utm_source, utm_campaign) IMPORTANT NOTICE ──────────────── Signal Layer is a heuristic statistical tool, not an AI authorship detection system. The Human Trace Score measures linguistic repetition and structural uniformity — it is not a definitive proof of AI generation and must not be used as the sole basis for academic, disciplinary, or legal decisions.
