About Dexter

Dexter is an open-source autonomous financial research agent designed for stock analysis and deep financial research. Built for developers and financial analysts, Dexter operates similarly to Claude Code but specializes in financial domains. It accepts complex financial questions and autonomously decomposes them into structured, step-by-step research plans. The agent then executes these tasks using live market data from the Financial Datasets API, continuously self-reflecting and refining its outputs until it arrives at a confident, data-backed answer. The project is hosted on GitHub and is intended for educational, entertainment, and informational purposes only. It is not a substitute for professional financial advice and explicitly warns against using outputs for real trading or investment decisions without consulting a licensed advisor.
