Isn't Microsoft Recall also 100% on device?

Microsoft Recall is completely on-device (or so they say).

It's mostly the screenshots things that get people. Semantic search is ok if the index is properly secured and privacy is a concern. And localized context is ok too (summarizing one web page does not screenshot my whole screen). I believe Microsoft has gone with building the easiest option (recording everything) instead of thinking about better contextual integration.

Those are pretty big If's when you have a webkit or blink-based browser on the same device.
