Raghavan will be replaced by longtime Google executive Nick Fox, who will take on the role of leading the search engine and ads products. Meanwhile, Raghavan will assume the role of Chief Technologist, partnering closely with Pichai and other Google leaders to provide technical direction and leadership.

Raghavan's departure marks the end of a remarkable 12-year tenure at Google, during which he has played a crucial role in shaping the company's AI products. Under his leadership, the Gmail team launched Smart Reply and Smart Compose, the company's first AI-powered email features.
