I used to just use a cloud service like you years ago, but try sync them through GitHub, there is a 1gb limit on private repositories though, but it should be fine as long as you don’t put videos and sounds in there.

There are tons of alternative ways for you to sync notes. I have used it for so long without spending a dime.

Oops, I didn’t even notice.

Man, you left out Obsidian, it is a godsend for studying and notetaking.

Get an ultra-wide monitor, split it into four panes, one pane to import the pdf you want to read, another for note-taking, and spare another one for the AI for Markdown formatting and explaining texts (optional). I can’t think of a more efficient workflow for studying digitally.

I have:

-Brave as my browser

-Ublock Origin

-DNS-wide AdBlock

-Youtube sponser block

I barely see any ads now, except those that pop up as an overlay and nag you, and some of them can be block manaully.
