I use https://pinboard.in for bookmarks. Tag the URL with the search terms I would have used if I were to find it again using google.

Having one of the mobile apps that support pinboard is also an essential part of my workflow.

I use Google Keep for more general life stuff, general notes I need to remember when people tell me and even shopping lists.

For development and work notes, I rely on the desktop version of https://boostnote.io/.
