How SignalShield works
Extension scans happen in your browser. Stock reports and research papers live on the website.
Install the Chrome extension
Add SignalShield from the Chrome Web Store. It sits in your sidebar while you read articles, Reddit, X, newsletters, and PDFs.
Open content and click Scan
SignalShield reads the visible page text and evaluates credibility risks: promotional framing, missing context, unsupported claims, verification gaps.
Review score, concerns, and checklist
You get a credibility score, a summary of key concerns, and specific verification steps: what to check before you trust the content.
Stock reports (optional)
At signalshield.io/report, generate structured investor reports with financials, valuation, and AI summaries. Separate from extension scans.
Research papers (free)
Browse public PDF deep-dives at /research. These are company research papers, not the same as the paid Research subscription plan.
Three products. One subscription.
SignalShield is not one thing. The Chrome extension scans content for credibility risks, stock reports build structured investor research, and research papers are a separate public archive. The Research plan unlocks the extension and reports.
Scan any financial content you read. Credibility score, risks, verification checklist.
