Notes in chess

I noticed that there was a note option in while playing chess on lichess. I was just wondering if any of you used notes and what you wrote about.
I'm not a pro at chess, and I don't play on lichess often either but I can't even begin to think about what I would ever use notes for. Would you write about a diagonal you wanted to remember or something? I think I could just remember that anyway, it doesn't seem very practical to me. I'd love to hear what you guys use notes for and maybe I'll start using them on longer games.
Thanks and have a nice day.

I don't use notes, but I know that taking notes during the game is helpful for analysis after the game. For example, you can type different moves and variations that interested you during the game and why, and then once the game is finished, you can compare your thoughts with a computer analysis and look at what worked, what you missed, and how you can improve your thought processes while playing.

It also helps if long games make you forget why you made certain moves by the end of the game, so you can refresh your memory during post-game analysis. That's what happens to me sometimes because my memory is like a goldfish after using 100% of my brain power on a chess game.
