Zazu — household / concierge lane: options → parent approval → RSVP, assignment, calendar holds (Assistants · Family Life · household · concierge).

Score table
Assistants Index · ONYT-2026-09 · m-2026-09-v1 · U.S. market
| Dimension | Zazu | Muse |
|---|---|---|
| Overall | 92.3 | 76.8 |
Execution | 96 | 86 |
Household | 98 | 64 |
Memory | 88 | 86 |
Privacy | 86 | 46 |
Availability | 94 | 96 |
Value | 84 | 88 |
Weights: Execution 30%, Household 20%, Memory 15%, Privacy 15%, Availability 10%, Value 10%.
Muse’s Availability (96) and Value (88) reflect Meta reach and free-cap pricing. Household (64) and Privacy (46) explain why it is not ranked as a two-parent product. Muse is not on the Family Life Index this edition — do not invent a Family Life row.
One-person agent vs family graph
Muse (U.S. launch 8 Sep 2026) is Meta’s personal agent — not the Meta AI chat bubble. You message it in WhatsApp or the Muse app; it runs on a dedicated Secure VM; it can mail, book, shop (Link by Stripe), and keep working after you close the phone. Real execution for one adult. App Store listing is 18+; launch is U.S.-only. The Index record shows no household graph or two-parent consideration loop.
Zazu treats the household as the user. Forward an invite or school email in WhatsApp. It lays out options, waits for an adult to choose, then RSVPs, assigns the next step, updates calendars, and loops in the right people.
Honest framing: WhatsApp presence ≠ family concierge.
| Moment | Muse | Zazu |
|---|---|---|
| Book a restaurant for you | In lane — personal agent | Possible, not the product center |
| Early dismissal + who picks up | One adult’s thread | Options for both parents; assignment after approval |
| Kid birthday RSVP | You remain project manager across people | Forward → options → RSVP + hold after you choose |
| Partner / sitter in the loop | Not a shared household product this edition | Built for two adults and age-appropriate kids |
Privacy and trust (sourced)
Muse Privacy: 46. Index sources: Meta launch post, Axios, Reuters (8 Sep 2026) — training opt-out, encrypted VM promised later, Reuters reporting on stalled/over-shared internal tests. Baggage to read, not scare copy to invent. Verify Meta’s live controls before connecting mail, payments, or calendars.
Zazu Privacy: 86. Approval before action; still a third-party with household context — read Zazu’s live privacy policy before connecting email or calendars.
Pricing
Muse (U.S.): Free with a cap; Power $20/mo; Maximum $100/mo. Platforms: WhatsApp · iOS · Android · Web. U.S. adults only at launch.
Zazu (U.S.): Concierge plans; start on WhatsApp. Generally available.
Compare on the job: Muse Value 88 tracks the free tier; Zazu Value 84 is concierge pricing for follow-through — different sticker for a different hire.
When to pick Muse
Choose Muse when:
- You want a personal agent that operates apps, mail, and shopping for you
- You live in WhatsApp / Meta surfaces and accept Meta’s data story after reading it
- You are 18+ in the U.S. launch window and do not need a shared family graph
- One-adult errands matter more than two-parent handoffs
When to pick Zazu
Choose Zazu when:
- Two parents need assignment + execution, not only a one-person agent
- School email, invites, and last-minute changes already live in chat
- You want options → parent approval → action with the household as the user
- Privacy posture and kid-adjacent logistics matter more than Meta’s connector surface
Partner
Onyt partner · same published rubric
If the job is household follow-through — shared options, RSVPs, handoffs — try the Index leader on WhatsApp.
Options first, then action after you approve.
Zazu is an Onyt partner; both products use the same published weights for this edition.
When both
Some adults may keep Muse for personal errands and Zazu for the family thread. Two vendors, two privacy policies, two habits. Do not assume Muse “sees” the household the way a family concierge does — the Index record does not support that claim.

Questions
Is Muse a family assistant?+
Not on this Index. Muse is a personal agent (Household 64). Launch is 18+ / U.S.-only. WhatsApp overlap is channel, not category.
Does Zazu beat Muse at everything?+
No. Muse Availability (96) and Value (88) are strong; Execution (86) is serious for one-person work. Zazu leads on household coordination and privacy for this hire.
Why is Muse’s privacy score low?+
Edition ONYT-2026-09 cites Meta’s training/opt-out story, deferred encrypted VM claims, and Reuters on mishandled access in tests. Read primary sources and Meta’s live policy.
Can Muse replace Zazu for school logistics?+
Not as a two-parent product. You would still be the project manager across people.
Does partner status inflate Zazu’s score?+
Zazu is a labeled partner. Same published Assistants weights (m-2026-09-v1) as Muse. See methodology.
Is Meta AI the same as Muse?+
No. Meta AI is the chat layer; Muse is the newer personal agent. The Index lists them separately.
