Muse vs Gemini Spark
Two platform giants, two contrary wagers: one agent comes to your chats, the other stays at home inside Google's apps.
Meta and Google have placed contrary bets. Muse turns up in WhatsApp free of charge, handling shopping, bookings and Marketplace listings. Spark stays inside Gmail, Calendar, Docs and Photos, running jobs on timers and triggers, and costs Americans $19.99 a month. Neither can be had in the EU or Britain. For most Americans the choice comes down to errands versus admin; beyond Canada and America, Spark on Ultra may be the only one of the pair you can buy.
| Muse | Gemini Spark | |
|---|---|---|
| Price | Muse charges nothing for 100 million tokens weekly, then $20 or $100 a month. | Spark is $19.99 a month through Google AI Pro in America, or from $99.99 monthly with Google AI Ultra. |
| Availability | Muse serves adults in Canada and America only. | Spark comes with the American Pro plan and with Ultra across most other supported countries, but Britain, Switzerland, Nigeria and the EEA are excluded. |
| Where you talk | Muse answers in its phone app, the Mac app, muse.ai and WhatsApp. | Spark lives in the Gemini app and inside Gmail, Chrome and Photos, never in a chat app. |
| Best jobs | Muse is at its best with shopping, bookings, Marketplace selling and reminders. | Spark is at its best with timed and triggered chores throughout Gmail, Calendar, Docs and Photos. |
| Your data | Muse keeps duplicates of your linked email and files in its own Secure VM, where a researcher has already found a flaw. | Spark draws on what Google already stores for you and waits for confirmation before sensitive steps. |
| Getting started | Muse takes about five minutes, though even the free tier will not open without a payment card. | Spark takes about ten minutes, most of it spent granting access to particular Google apps. |
Pick Muse if you are an adult in Canada or America and fancy offloading errands for nothing. It suits anyone who would rather send a WhatsApp message than open another app.
Pick Gemini Spark if your mail, calendar and files already sit with Google and you would like an agent familiar with them from the outset. Beyond Canada and America it is also the only one of the pair on sale, via Ultra, in the countries Google covers.
For errands and purchases, Muse is the stronger place to begin, and it costs nothing. Spark keeps an inbox and a calendar in better order, and outside Canada and America it is the sole option of the two for anyone prepared to pay Ultra prices.

Questions readers ask
Is Muse better than Gemini Spark?
For shopping, bookings and selling, Muse is the stronger and cheaper choice, since its free tier covers 100 million tokens weekly. For recurring work inside Gmail, Calendar and Docs, Spark fits better. The answer depends on whether your chores are errands or admin.
Can I use Muse or Gemini Spark in Europe?
No. The EU and Britain are closed to both. Muse is confined to Canada and America, while Spark shuts out Britain, Switzerland, Nigeria and every EEA member on all plans.
Can I talk to Gemini Spark through WhatsApp like Muse?
No. Spark is absent from every chat app; you reach it in the Gemini app or inside Google's own products. Muse, by contrast, can be messaged straight from WhatsApp with the same memory as its own app.
