OneNote's Linked Notes Taking does exactly this. You can combine it with the "Dock to Desktop" / Docked Window feature which makes it hijack a part of the desktop space (to the RHS, typically) so that you can continue to take notes while reviewing stuff on the LHS. The window on the LHS can be another OneNote window (or one of the other Office applications), and as you type in the RHS, docked window, sentences are automatically linked to the page and line on the LHS.
Unfortunately, I didn't find a single video showing the power of both Linked Notes AND Dock to Desktop, but these two show the usage of these features separately:
Does OneNote generate back links? If I pull up a note, I'd like to see not just the notes it links to, but also the notes that link to it. It's probably the one thing I wish Evernote would add.
i'm using "OneNote for Windows 10" which seems to have lost a lot of the power features. It looks like both Dock to Desktop and Linked Notes have gone.
there are so many power features that were removed after OneNote 2016 - it makes using Onenote obsolete nowadays - hate to start using another note taking method now
