I either take notes on paper or in a text file. CherryTree, ZimWiki, Obsidian, etc- none of these stick, and I end up with folders of assorted file types. Well-named textfiles are best so far, as I don't care to use markdown, and I can do full search of the text.
I used to use Pocket and found it urgent and generally not important, relative to books I choose to read, so I uninstalled it and have come to terms with never reading the thousands of articles I've saved over the years.
