Hedge fund Citadel has introduced an artificial intelligence-powered research tool to speed up analysis for its equities investors, according to a report by Reuters citing chief technology officer Umesh Subramanian.

The Citadel AI Assistant — a chatbot trained on licensed data including transcripts, regulatory filings, brokerage research, and the firm’s own strategies — is designed to surface risks, generate tailored research, and create reading lists aligned to an investor’s portfolio.

Subramanian said the tool now sees regular use across almost all of the firm’s equities investors. However, he cautioned that investment decisions remain for humans.

The launch comes as hedge funds continue to weigh the practical benefits of generative AI. Citadel founder Ken Griffin noted in October that the technology has yet to meaningfully improve returns across the industry.
