Google has announced a significant update to Gmail, introducing an AI-driven search feature that prioritizes email relevance over the traditional chronological order. This enhancement considers factors such as recency and user interactions to streamline email retrieval. Users can toggle between 'Most relevant' and 'Most recent' views, catering to personal preferences. This global rollout for personal accounts is expected to improve user efficiency in finding important emails. The update aims to strengthen Gmail's competitive edge against Apple's Mail app, which has also adopted similar functionalities recently.
