About SignalX

What we do

Public companies file a constant flow of documents with securities regulators: annual reports, quarterly results, disclosures of material events, insider trades, and institutional ownership. The information is public, but it is scattered across thousands of filings, written in dense legal and accounting language, and published faster than any one person can read it.

SignalX indexes those filings the moment they are published, extracts the structured financial data inside them, and generates section-by-section summaries grounded strictly in the source text. The result is a single place to follow what companies are disclosing, what insiders are buying and selling, and where institutional money is rotating, without paying for an institutional terminal.

What we cover

United States (SEC EDGAR): 10-K annual reports, 10-Q quarterly reports, 8-K current reports, 20-F and 6-K foreign issuer filings, 13F-HR institutional holdings, Form 4 insider transactions, and SC 13D/G activist and passive ownership disclosures across the S&P 500, Nasdaq 100, and Russell 2000.

Korea (DART, beta): 사업보고서 (annual reports), 분기보고서 (quarterly reports), and 주요사항보고서 (material event reports). Korean coverage is in beta as we expand entity mapping and translation quality.

How the analysis works

Financial figures come directly from the SEC's structured XBRL data, not from screen-scraping, so revenue, net income, EPS, and 100+ other metrics map to the exact tags companies report. AI summaries are produced by large language models (Claude, with a GPT fallback) under strict grounding rules: a summary may only use numbers and claims that appear in the filing itself, with no invented detail or padding. Each bullet points back to the section it came from.

We treat accuracy as the product. A summary that reads well but drifts from the source is worse than useless in an investing context, so the prompts are tuned to favor faithful, checkable statements over fluent prose. Summaries are a starting point for your own research, not investment advice.

Who operates SignalX

SignalX is built and operated by two affiliated entities:

• Viva Technologies Lab, LLC — a limited liability company registered in the United States, which operates the web service at signal-x.app.
• Viva Technologies (비바테크놀로지스) — a sole proprietorship registered in the Republic of Korea, which publishes the SignalX Android application on Google Play.

We are an independent product and are not affiliated with, endorsed by, or sponsored by the U.S. Securities and Exchange Commission or Korea's Financial Supervisory Service. All filing data originates from those agencies' public systems.

Data sources & independence

Filing content is sourced from SEC EDGAR and DART, which are public government systems. Stock prices are retrieved on demand and cached. SignalX does not sell filing data back to the agencies, and we do not accept payment to alter, promote, or suppress any company's analysis. The summaries you read are generated by the same pipeline for every company, large or small.
