This is what it does
Open the signal board
Four keyless public sources — SEC filings, insider Form 4 transactions, sentiment scored over the filing text, and daily market bars — scored into one signal per ticker, with the contributing sources attached to every row.
Hosted service — runs on its own domain, not from this page
The beta is a scheduled Cloudflare Worker, so it cannot run inside this page. Every 30 minutes it fetches SEC EDGAR submissions, parses the raw Form 4 XML, scores the filing text with this product’s own analyzer and reads daily bars, then applies the same scoring rules as the Node engine — the rules live in one shared module both hosts import.
Status is on the board itself: each run records what it attempted, fetched, parsed and failed, and prints its last-run time. A run that finds nothing above the 0.70 threshold says so in its own counters instead of looking broken.
- What it does: scores filings, insider trades, filing-text sentiment and daily bars into one confidence per ticker, above a 0.70 threshold, with corroborating sources boosting the score and a risk adjustment lowering it.
- What to try: read the last-run line first, then open a ticker. Nothing is seeded, so what you see is what the most recent run measured.
- What it does not do yet: no account, no alerts or email, no payments, no intraday ticks, and no news or app-intelligence feed — the two sources that need keys are listed as absent with their reason in
/api/meta.

What is built today
- A hosted beta is the live surface. It is a Cloudflare Worker with a D1 store and a 30-minute cron, and its board carries the last run with the per-source outcome, so a failed fetch is visible rather than silent.
- The backend is written and its suites pass. Seven suites and 58 tests run green, with a clean type check.
- Each source is parsed on its own terms before they are combined, deduplicated per ticker and type, and the contributing sources travel with every row.
The score ranks what the sources said against each other and shows the working behind the ranking. It is not investment advice, and nothing here places an order.
Under the hood
What it is built on
- Stack
- Node.js and TypeScript (Express, PostgreSQL, Expo/React Native) for the full engine; a Cloudflare Worker with D1 for the hosted beta. Both import the same scoring-rules module.
- Surfaces
- The hosted beta board, a REST API and WebSocket hub, and the Expo mobile client. The hosted beta has no account and no alerts.
- Tested by
- Jest unit and API suites, a pg-mem integration test over the migrations, a strict type check, and a GitHub Actions workflow on every push.
