I think that the difference between that app and the proposed app in this branch of the comments, is that that app is just an LLM echo chamber for your journal.

I think that the difference between that app and the proposed app in this branch of the comments, is that that app is just an LLM echo chamber for your journal. It would be different if you also saw posts from other people that you could react to, like on more traditional social platforms. Maybe the right mix is to have an LLM-botfollower-army feature that you could purchase in existing social media apps, but your botfollowers are only visible to and only interact with you. Also there should be a lot of different prompts for the botfollowers so that they don't all sound the same, e.g. the prompts would drive different personalities for the bots. Perhaps an algorithm could generate prompts based on archetypes mined from existing social media.
