Signal Trust Profile

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.
