The short answer
This comparison covers Meta Muse, the personal agent announced by Meta on September 8, 2026. Meta describes Muse as an agent for one person, available through Muse apps and WhatsApp during its US rollout. Nema is built for company work that a team carries out in shared Slack channels.
Muse can keep working on its own virtual computer after the user closes the app. Nema keeps the team request, source discussion, and approval together in Slack. The choice starts with ownership. Does the agent belong to an individual, or to the people working in a channel?

A renewal example
An operations team is reviewing a vendor renewal. The inputs include the signed agreement, usage export, service notes, and a decision deadline. The team needs a brief that separates confirmed terms from unresolved questions and assigns a reviewer.
With Nema, a teammate starts in the vendor channel. The coworker follows that channel's instructions about approved sources and output format, then posts the brief in a thread. Other members can correct a date or add a missing record. A proposed follow-up through a connected app can pause for the operations lead's approval. The channel retains the shared guidance for the next renewal.
Muse fits a personal version of the job. One person could ask it through the app or WhatsApp to navigate a vendor website, fill a form, or handle personal logistics. Muse runs in a dedicated Secure VM with its own browser. Meta also describes an audit trail, scoped app access, a Sentinel agent that reviews outbound internet actions, and approval before sensitive email or purchasing actions.
Choose Nema when
Choose Nema when several people must see and continue the work. A channel coworker can have an explicit brief, connected tools, memory, and named approvers. The request and review stay alongside the team's discussion instead of living in one person's assistant history.
Nema also gives an organization model choice, recurring team routines, and administration designed around company Slack work. These qualities fit operating processes where responsibility moves between people.
Choose Muse when
Choose Muse when the agent should work for one person across work and daily life. Browser-based completion, WhatsApp access, mobile use, and agent-assisted purchasing are central parts of Meta's offer. Muse uses the Muse Spark model and can continue after the user leaves the app.
Meta describes the current launch as a US rollout that is free for most use, with paid options planned for heavier use. Its launch material does not document shared Slack channels, organization roles, team memory, or company-wide administration, so buyers should treat those capabilities as unconfirmed.
Evaluate sensitive actions
For Muse, review how credentials enter the Secure VM, when Sentinel intervenes, what the audit trail contains, and how one-time payment cards work. Meta has also announced future 1Password and user-keyed Confidential VM support. Treat announced features as future work until they are available in the account being evaluated.
For Nema, connect one real business app and test an allowed read, a denied read, and a proposed write. Confirm whose permissions apply and who can approve. The safest decision comes from observing the same bounded task, not from comparing broad app counts.
Common questions
Is Muse made by Meta?
Yes. Meta announced Muse in September 2026. This comparison covers Meta's personal AI agent.
Does Muse work in Slack?
The reviewed Meta sources document Muse apps and WhatsApp. They do not document a shared Slack experience. Ask Meta for current integration details if Slack is required.
Can Muse be shared with a team?
Meta's launch material describes a personal agent. It does not publish organization roles or shared agent administration. Nema is designed for shared channel work, so it is the clearer fit for that requirement today.
