Meta's consumer AI agent Muse has extended its phone call delegation feature to paid subscribers in the United States, enabling it to place calls to U.S. businesses on users' behalf to handle tasks such as cable TV services, DMV matters, and restaurants that don't support online reservations. The feature underwent a limited test in September. Muse now has over 10 million users and offers two subscription tiers: $20 per month for 500 million tokens per week, and $100 per month for 3 billion tokens per week. Its email address creation feature will soon be available to free users. Competition in the AI call-making space is heating up, with several players having rolled out similar services, and advances in AI voice realism are making it increasingly difficult for businesses to distinguish AI callers from human ones. The feature is expected to ease pain points such as waiting on hold for phone customer service and being repeatedly transferred, but business acceptance, identity verification rules, and future regulation remain to be seen.
