  description

  Signal helps you evaluate whether an article gives visible reasons to trust it.
  
  When you open an article, Signal analyzes the page locally in your browser and creates a Trust Score based on visible signals such as authorship, source support, source range, publication information, commercial pressure, and whether key claims have nearby supporting sources.
  
  Signal can also:
  • Summarize the article
  • Extract key claims
  • Show whether claims have nearby source support
  • Highlight referenced documents that are not linked
  • Show cited sources and source context
  • Explain how the Trust Score was calculated
  
  Signal does not decide truth. It evaluates whether the article makes its claims verifiable.
  
  All analysis runs locally in your browser. Signal does not send article text to a server, does not use Gemini, OpenAI, or any external AI API, and does not sell browsing history.

  Signal is a browser-native transparency layer for the modern internet.
  
  Online content often makes claims without showing clear evidence, source transparency, or meaningful accountability. Signal helps solve that problem by calculating a Trust Score based on the visible evidence structure of a page.
  
  Signal does not decide what is true.
  
  Instead, it helps you answer a different question:
  
  How well does this page support what it is saying?
  
  What Signal does
  
  When you open Signal on a page, it analyzes observable indicators such as:
  
  author presence
  publication metadata
  citation count
  source transparency
  evidence structure
  commercial signals
  nearby source support for key claims
  
  Signal then generates a Trust Score and a detailed evidence profile so you can inspect the reasoning behind the result.
  
  Key features
  Trust Score
  Quickly see a page’s evidence-based trust rating.
  Claim analysis
  View key claims and whether nearby listed sources appear to support them.
  Source visibility
  Inspect citations, source patterns, and evidence transparency more clearly.
  Page-type awareness
  Signal adapts to articles, research pages, reference-heavy pages, PDFs, YouTube pages, and more.
  Local history
  Revisit previously analyzed pages with stored hostname, title, Trust Score, and analyzed time.
  Explainable scoring
  Signal shows why a page received its score instead of hiding the logic behind a black box.
  Why Signal exists
  
  Much of the internet is optimized for attention, not clarity.
  
  Reporting is often missing:
  
  source transparency
  strong citation practices
  clear attribution
  accountability for claims
  
  Signal was built to make those things more visible.
  
  Signal is a transparency tool.
  
  It helps surface the evidence structure behind content so you can make your own judgment.
  
  Privacy
  
  Signal is designed to be lightweight and practical.
  
  local history is stored locally in your browser
  Signal does not need to store full article text to provide its core functionality
  the goal is to help users inspect information, not collect unnecessary data
