State Street announced plans to deploy Microsoft Copilot — an AI assistant built on OpenAI's large language models — to help employees with workplace tasks such as answering policy questions, scheduling, and navigating internal applications.

State Street executive vice president Caroline Arnold publicly stated in 2023 that the company's Office of Architecture was preparing to scale the use of Microsoft Copilot across the bank. Described use cases included a 'chatbot concierge' for employees to get answers to HR and policy questions, book conference rooms, and reduce friction in internal workflows. The source confirms planning and scaling preparation, but does not confirm full production deployment across all employees.
