I thought this was a serious take for a second (until I looked at microsoft_recall_linux.exe - lol). Having said that, I would actually be keen for something similar that is both open-source and totally local so that I could use the output as AI fodder (for a local inference model of course).
Same. I have a terrible memory so a totally local ai that knows everything I do would actually be useful.
If the system worked fully locally, didn't come from Apple/Microsoft/Google/Facebook/etc., and had decent data isolation, I would probably turn it on.
Unfortunately I find that getting basic OCR to work reliably on Linux is a challenge in itself compared to Windows' APIs and quality of OCR results, so I doubt an honest, well-intentioned implementation will make it to Linux.
