All your WhatsApp messages are put into some Obsidian folders.
Why? I personally don’t like short reciprocity messages and prefer delayed and high quality messages/conversations, so I usually copy and paste all my communication channels messages in Obsidian and digest my answer over time until I consider it ready to send, with some help from GPT3 and other processing hacks like Insert conversation starters generated by AI for your future conversations · Discussion #952 · SilentVoid13/Templater · GitHub.
I’ll probably implement this as a hack with Templater soon, probably use some WhatsApp scrapper since there is no official API for this. I could imagine an Obsidian plugin.
Ideally, you can even send messages from Obsidian, but that’s a nice to have
Of course this idea could be implemented for all other communication channels (Discord, Slack, Matrix, whatever-u-use)
