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 delivered as Word documents.
* 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.
