# Lexfi

> Lexfi is an AI research operating system for institutional investors. It converts qualitative financial information (earnings calls, filings, central-bank press conferences, news, and regulatory disclosures) into explainable, point-in-time investment signals, delivered through Claude and other MCP clients, OpenBB, and a REST API.

## What Lexfi Is

Lexfi is a financial data and signal provider, not a trading platform or brokerage. Every signal is traceable to the source language that produced it, with the historical market reaction attached. Clients consume Lexfi inside tools they already use rather than through a separate interface.
