AI Assistants Learn to Call: Instinct and Muse Add Voice
Instinct and Meta's Muse can now make phone calls for users, adding live voice to the race over personal AI agents. The parallel updates were reported on September 17, 2026. TechCrunch
San Francisco-based Instinct calls its feature Instinct Concierge. It handles jobs that still need a human on the line, such as booking restaurants without online reservations, joining a dentist's cancellation list, and fixing a cable bill problem. As of September 17, Concierge was in early access for some users, with a plan to expand to all users.
Meta's Muse can now place calls to U.S. businesses. Meta said it will roll out first to users who ask Muse to make a call. The change arrived fast. Muse launched in the week before September 17.
The calling features build on transaction work both assistants already did. Instinct and Muse can make restaurant reservations and cancel subscriptions. In early September, Instinct gave its assistant its own email addresses to handle account sign-ups and account management. It also lets a user's assistant talk to other people's assistants for certain tasks, once those users are added to a trusted network. Instinct remains invite-only.
Meta is asking for wider access. Muse seeks permission for users' email, calendars, payments and health services. TechCrunch At launch, Meta described an agent that can use other apps to send emails and make payments, and that can send emails, book travel and sell a car on a person's behalf without step-by-step direction.

Early download numbers put Meta ahead. Sensor Tower reported Muse passed 730,000 downloads in the U.S. in its first few days, compared with 707,000 downloads for the Meta AI app in its first five days after launch. The Muse app reached No. 2 in the U.S. top charts.
Instinct is working from a smaller user base with large private funding. It raised $350 million at a $2.5 billion valuation in August 2026, and as of September was reportedly in talks to raise $1 billion at a $10 billion valuation. Friction has started to show. Resy deactivated a user after he tried to land a hard-to-get reservation using Instinct's AI agent. Inc.
The broader context here is that voice covers what software connections do not. An API, a standard way for programs to exchange requests, still misses many small businesses. The pattern is familiar: simple online booking first, then email addresses and assistant-to-assistant messages, then regular phone calls for the long tail of dentists, local restaurants and support lines. That makes call quality, transcription accuracy, how the system handles pauses and delays, and whether it identifies itself as an AI into core engineering work, not extras.
In my view, the near-term limit will be policy as much as technology. Businesses that block bots online will need rules for persistent voice agents, and users will need to decide how much email, calendar and payment access to grant for hands-free help with routine calls. Worth flagging is the payoff if those controls work. Handing hold music and reservation redial to a supervised agent is dull work, and it is the kind of work that decides whether agents shift from demos to daily use.
