Google is refining its Circle to Search feature by introducing a follow-up search bar at the bottom of the screen to enhance user interaction. This simplified interface includes a new AI Mode that allows for voice input and context-specific queries. The feature is currently in beta testing and is not yet available to all users. The design aims to make follow-up queries more seamless, allowing users to explore further information without losing sight of initial results. The feature is being tested in the latest beta version of the Google app (version 16.47), with an uncertain timeline for a wider release.
