This has been out for a while now. But before this, what people used to do is create a group with just yourself as a member, and send messages there. You had to create a group with 2 people (yourself and someone else), and just remove them because it could not be done directly. And this could be used as notes or whatever.

Right now I message myself but let's say if one wanted to maintain a separate chat for notes or some other purpose, they could create an infinite number of groups with just them in it and get it working.

Of course I think OP's solution is offering an interactive experience more than just one way communicaton.

Using this method one can have multiple conversations with self with different contexts. I use one to keep the important docs handy like ongoing travel tickets etc. Another one for Shopping list. and another for saving links and watch later.

You have more WhatsApp-savvy (or considerate) friends than me – I’ve had people text me notes before (because I’m pinned or otherwise on top of their chat list). “Just ignore please, but I’ll need this in a bit” :)

Haha, my wife does this to me when she needs to save a link or some text.
