Sure, it's nothing super unique but the way that Meta has put all the pieces together including security works really well in practice. Muse seems to be the best of the AI personal assistants for regular people right now.
Grok as well seems to have a hit a sweet spot.
Does anyone believe the security works though? This is the company that brought us facebook, pervert glasses, and got sued by its E2EE content monitoring team (which apparently exists!) for emotional trauma because they had to read so much stuff from private WhatsApp messages.
