Ask HN: Do you use WhatsApp to make notes?

I use Signal's "note to self" as a sort of inbox for my notes system that I have on my computer. Y send the messages in the "note to self" chat, and once I process them, I add a thumbs up reaction to the message.

I also use it for sending links when I want to transition between devices

I use it to send photos and documents to and from my phone. These apps are cross platform, when Airdrop is not.
