Who each agent is built for
Claude Duet's launch story is a business owner: a daily dashboard from point of sale and payroll, a missing health permit, a hiring decision. Its headline connectors are Gmail, Slack, QuickBooks, Stripe and Shopify. It is a work agent first.
Muse is pitched at everyday life. Coverage describes it sending email, booking travel, filling out web forms, negotiating on your behalf and completing purchases, with a more consumer-friendly interface. Its presence inside WhatsApp also makes it easy for non-technical users to try. See our use cases page for the jobs Duet is designed around.
Safety: approvals vs a Sentinel agent
Duet approvals
Duet's rule is simple: four kinds of action, sending, paying, signing and deleting, always wait for you. A classifier screens for sensitive information, and logins happen in a private cloud computer. Details in the Claude Duet safety guide.
Muse Sentinel
Meta added a second agent, Sentinel, on the same cloud machine. Nothing Muse does reaches the internet unless Sentinel approves it, Muse still checks with you before things like sending an email or making a purchase, and there is a full audit trail. Two layers of checking sounds stronger, though it also means a second model whose judgment you are trusting.

What using each one feels like day to day
Specs only go so far. The bigger difference shows up in the rhythm of a normal week, and in what each agent decides is worth interrupting you for.
A working week with Anthropic's agent
The day starts with a short ranked brief: a client waiting on a reply, a contract renewal next week, an invoice thirty days late. Drafts are ready for each. Through the day it stays mostly quiet and checks in every few hours, messaging only when a decision is needed. Bigger jobs such as a weekly sales summary or a board deck come back as finished documents. It feels like a capable assistant who knows your business systems.
A personal week with Meta's agent
The emphasis is on errands: rebooking a flight, comparing prices for a purchase, filling in a school form, chasing a refund. Conversations can happen inside WhatsApp, which makes it feel closer to messaging a friend who gets things done. Its visible memory files make it easy to correct what it believes about you.
Where they overlap
Email and calendar are common ground. Both can triage messages, draft replies and propose meeting times, and both hold risky actions for your approval. If those are the only jobs you care about, the deciding factor is probably which ecosystem you already use and pay for. Someone deep in Google Workspace and QuickBooks will get more from Anthropic's connectors on day one; someone who runs their life through WhatsApp will find Meta's agent easier to adopt. Neither choice is permanent, and trying both on a single low-stakes inbox for a week is the fastest way to find out.
