They do make some effort to push the “confidential cloud” aspect of their product, where the AI is supposed to somehow operate on your encrypted data, but these days I only believe it when I see the white paper. It is unfortunately quite common in our industry is to posture as more security-conscious and privacy-focused than you actually are.

I’m gonna doubt they’re operating AI on encrypted cloud data. In other words, there’s no technical reason they couldn’t be listening to your conversations.

If these guys have accomplished homomorphic encryption they shouldn’t be building a wearable, they should be licensing their IP to Apple.

They're definitely marketing this as if they were Apple. If this takes off I'm betting on Apple buying them out.

Every rumor points at Apple announcing OS integration of local LLM assistant stuff at WWDC in June, with specialized chips to go with it. I suspect they're going to Sherlock a lot of small "AI" companies simultaneously.

It's encrypted, but they have the keys. Wouldn't want anyone else to access the data without paying the toll, after all.

There’s three options:

1. The data is encrypted and they can’t operate on it in the cloud. 2. The data is not encrypted. 3. The data is encrypted and they have built a state of the art homomorphic encryption algorithm for their AI to operate on.

I’m going to guess it’s #1, not #3.

When I saw them compare it to E2EE, since that’s at least a specific thing that can’t really be misinterpreted, I thought they were serious, but turns out it’s not at all[1] and they are advertising themselves as being far more private and secure than they actually are. Considering their investor list[2], maybe this is more common than we realise?

It's all sent to OpenAI for the LLM processing, so you'd better make sure you're happy with them getting text transcripts of everything that ever shows up on your computer screen.

And for some reason that's not illegal
