Just out of interest, why are you keeping your chat history? What for? All my chats are set to burn after 6 months as standard but most are shorter than this.
I personally keep it all (on iMessage) as a bit of personal history. Trying to see conversations I had with friends and family around fun/important events, searching to see if I ever went on a similar tirade about a product I’m about to send a friend…
If you, after 20 years, can process all your chat history with a (locally run!) AI, you may find a lot of interesting things about yourself and your friends.
just curious.. why you are deleting your chats? what if you want to search them for something from a while ago?
