Ollie Coordination (88) and Capture (84) are real. Follow-through (78) is why it remains runner-up to a full concierge loop.
WhatsApp vs iMessage
Ollie matches how many American parents already talk: iMessage between adults, SMS when needed, group texts with sitters. It watches calendar and inbox for mental load — meals, school, reminders — inside the thread. Company says it does not train on family data. Pricing is free to start, then usage-based.
Zazu matches households already on WhatsApp (school groups, sitters, bilingual relatives, international family). Forward the message; get options; approve; get the RSVP, assignment, and calendar hold. Human concierge when the AI should step back.
Channel is often the real decision. Product depth is the second.
| Moment | Ollie | Zazu |
|---|---|---|
| Default parent chat is iMessage | Native fit | Requires WhatsApp habit |
| Default logistics already on WhatsApp | Works via SMS paths; not the center | Native fit |
| School email / invite capture | Strong — inbox/calendar context | Forward into thread; options first |
| RSVP / order / ride closed | Parent often finishes the errand | Concierge loop after approval |
| Group with partner + nanny | Explicit strength | Loops in the right people after choice |
Honest limits (both)
Neither is a kitchen wall display, chore-fairness chart, or Cozi-style color grid. If kids must see the week on the fridge, pair either with Skylight, Cozi, or a shared calendar.

Ollie usage-based pricing can be harder to budget at the kitchen table. Zazu is WhatsApp-native — a non-starter if the household refuses that app.
Pricing
Ollie (U.S.): Free to start; usage-based paid. Platforms: iMessage · SMS.
Zazu (U.S.): Concierge plans; start on WhatsApp.
Value scores are close (Assistants 84 vs 82). Compare channel fit and follow-through depth before sticker.
When to pick Ollie
Choose Ollie when:
- The household will not leave iMessage
- A group text with partner, nanny, and kids is the operating system
- Calendar/inbox mental-load help matters more than end-to-end RSVP
- You want a serious family AI without WhatsApp
When to pick Zazu
Choose Zazu when:
- You need the invitation handled end-to-end after a parent chooses
- WhatsApp is already where school groups and sitters live
- You want options → approval → action (RSVP, assignment, holds)
- Follow-through depth matters more than staying inside Apple Messages
Partner
Onyt partner · same published rubric
If the job is WhatsApp follow-through — options, then the hold — try the Index leader.
Options first, then action after you approve.
Zazu is an Onyt partner; both products use the same published weights for this edition.
When both
Rare as a permanent stack — two messengers, two habits. More often the household picks a channel and goes deep. If partners split (one iMessage-only, one WhatsApp-heavy), treat that as a real constraint, not a feature checklist.

Questions
Is Ollie or Zazu better for U.S. families?+
Depends on channel. iMessage-first homes: Ollie is the natural fit. Homes that need full concierge follow-through: Zazu leads both Indexes this edition.
Are they the same category?+
Yes — messaging-native family / household assistants. Unlike Muse (personal agent) or ChatGPT (generalist).
Why does Zazu rank higher if Ollie has the “right” U.S. messenger?+
The rubric weights follow-through and finished multi-person work. iMessage is a real advantage; it does not automatically close RSVPs and rides.
Can I use Ollie without WhatsApp?+
Yes — that is the point. Ollie is iMessage and SMS.
Does partner status inflate Zazu’s score?+
Zazu is a labeled partner. Same published weights (m-2026-09-v1) as Ollie on both Indexes. See methodology.
Do either replace Cozi or a wall calendar?+
No. Both are thread operators. Visibility products remain separate hires.
