I feel like those can be solved already by searching through your emails/browser history.

Recall won’t help with that. You also don’t need an AI for the second one. Just something more than a basic shell.

I honestly don’t understand the use case. What do you find interesting about it?

Yes. See Sennheiser versus Beats.

The Firefox add-on works great, and I’ve never really needed more than that and the website. On Android I have a 3a too and not noticed this issue.

I’m using an anonymous browser and for me often DDG has better results than Google now. My Google-fu used to be on point but recently I can’t seem to find sites that aren’t SEO traps.
