Marginal AI

ClaudeCommunityby Quantimental Technologies Ltd.

Marginal AI tracks the extraordinary events that move markets: agentic intelligence and alternative data for economics and US-listed securities, with a sourced citation on every claim. Connect it to Claude to get: - Extraordinary events and earnings & guidance for US-listed companies, organised in a proprietary ontology of about 500 event types across 8 categories (M&A and restructuring, litigation, regulatory and legislative actions, accounting adjustments and non-recurring items, operational and technological disruptions, force majeure and environmental events, market and economic shocks, earnings and guidance). Each event is deduplicated across sources and carries every corroborating source, a point-in-time first-seen timestamp and the price reaction around it. - Company financials exactly as reported to the SEC, each figure tied to its filing and accession number. - Macroeconomic series (rates, inflation, employment, growth, commodities) with units and freshness. - Industry groups and the companies in each, for screening. - Research questions answered by the Marginal AI analysis engine, brief or Deep Dive, drawing on filings, earnings calls, news, court and regulatory records, central-bank and IMF material and academic research, with citations. Use it to check what happened at a company, monitor new events, backtest without lookahead, or build sourced research. It is impersonal factual research: Marginal AI gives no investment advice and does not connect to brokerages or place orders. Requires a Marginal AI account (free plan available). Data calls use the account's Compute Units: 0.5 per call, lookups free, research priced like a chat question.
