I came here to recommend it as well. It's wonderful for this. My memory is shit but I have enough of it to be like... wait I think I did something with this once... and then search my vault for my notes. I used to use OneNote but Obsidian is 1000% better. I love how fast it is to create a reasonably documented note if you have a template set up.

My workflow for anyone interested:

Ctrl + O

Type the title which shows you if theres anything that already has this name where you might want to add this instead of making a new note (assuming you have a naming scheme).

Shift + Enter to create the note.

Ctrl+~ to add template. Paste info, paste url and make whatever notes I want.

This leaves you with an easily searchable vault of notes which you can further organize with tags/links pretty much however you want.
