Replace + extend with natural language to rephrase the segment — so that future demo iterations can be ten times faster.

Google Flow Music is officially launched, renaming ProducerAI to flowmusic.google, joining the Google Flow family. Added replace and extend two remix capabilities, allowing users to select segments with natural language for the AI to modify, such as extending the intro into dubstep, replacing multiple chorus sections, or providing alternatives for guitar solos. The workflow shifts from "whole song regeneration" to "local control," aligning more closely with the iterative pace of professional music production.
