Marginal AI: Deep-Reasoning Event Intelligence for Economics and U.S.-Listed Securities Marginal AI delivers agentic intelligence and alternative data for economics and U.S.-listed securities. It delivers personalized agentic reports, notifications, text alerts, and deep-reasoning chat, 24/7. Most tools focus on the normal course of business. Marginal AI covers that and what falls outside it: extraordinary events, the sporadic, unpredictable, and often high-impact developments that incumbent providers under-cover and general AI models struggle to surface reliably. WHAT YOU CAN DO * Deep-reasoning chat: Ask what happened, why it mattered, and how we know. Every claim links to its primary source, with general and specialist modes. * Agentic reports: Generate deep-research or summary reports on any company or theme, on demand or on a schedule, ranked by materiality and exportable to Word, PDF, or Excel. * Reports that learn your preferences: Edit a delivered report or request changes in plain English. Marginal AI applies what it learns to your current or future agentic subscriptions. * Delivery on your terms: Receive push notifications and text alerts at your chosen cadence, from real time to periodic. * Track what matters: Follow any company, person, team, group, phenomenon, event type, or theme. You control the topics, frequency, and depth. * Economics built in: Authoritative macroeconomic data feeds directly into retrieval. * Charts and screening: Visualize price and time-series data, then filter and rank U.S.-listed securities using financial metrics refreshed daily. BUILT FOR Investors and traders, sell-side bankers and research desks, lawyers, compliance and regulatory teams, consultants, researchers, data teams, and active individual investors. WHY IT IS DIFFERENT Marginal AI combines a proprietary event ontology, broad and specialized source coverage, provenance guardrails, multi-channel delivery, and configurable cadences, at a fraction of the cost of legacy providers and AI-native tools that do not specialize in extraordinary events. Every corporate event is deduplicated, corroborated, and sourced, with independent confirmations, market impact, and a verifiable citation for each claim, never a model-generated link.
