Fefi is an AI-powered finance dashboard built to enhance financial intelligence.
It helps users analyze market data — from individual stocks to broader financial trends — with artificial intelligence that delivers accurate, real-time insights.
At the core of Fefi is a finance and economics-focused chat, which responds to queries using live market data. The platform also includes a Markets page powered by AI, where users can monitor companies and assets, with information continuously updated from reliable sources.
A standout feature is the trading backtester with an integrated code editor. This lets users test strategies against real historical data and refine them in an AI-assisted environment.
Fefi also includes an AI interview simulator that recreates real-time interview scenarios across private equity, investment banking, and consulting — making it a valuable training tool.
Finally, Fefi can generate custom Excel reports and draw on trusted financial sources and official government filings, giving users clear, transparent insights for better decision-making.
