How this report works
Included are assistants whose catalog entry (checked 2026-10-26) lists the type as big tech. They are ranked by the average of all ten tests, with at least five taken. Scores come from the published score sheet and are dated 2026-10-27. 2 of the 3 ranked assistants (Norton Family Assistant and Gemini Spark) carry pre-filled scores, which are placeholder estimates the site has not yet replaced with its own test runs, so treat their places as provisional. Muse is not pre-filled.
How to choose
- Compare what each one is for. Muse completes tasks on a cloud VM, Gemini Spark covers chat, voice, research and creation, and Norton Family Assistant manages family calendars, school emails and forms.
- Check the data terms. In our catalog Muse records that it trains on your data by default, Norton Family Assistant that it does not, and Gemini Spark's entry is unclear.
- Look at where it works. Muse is in an app and on WhatsApp, and Gemini Spark and Norton Family Assistant are app-only in our catalog.

What users say
The agent, which Meta launched on September 8, booked a Friday date night and made a packing schedule for my upcoming move. It also emailed a friend about a trip next month and made a planning document with places we want to visit.
Open sourceWhen I asked for a list of places to go for date night, it pulled up two options in my neighborhood that had been closed for years.
