Where did you see this 50 third parties request? Maybe I just missed it on setup?
I think you might be overestimating that market segment tbh. I'm sure there's some folks who Hardline like you, but I'm sure that number is exceptionally low by percentage.
Also, I think it's totally valid to not want to share your data with a company, but I've seen a lot of confusion before as though Google is selling your data and just for clarity, that's absolutely not what they do. You don't want to have your data in their ownership? Valid. You don't want them to resell what they collect from you? Unfounded and a literal negative business value for them.
While I recognize the AI art is quite obviously derivative and considering that ML pattern matching requires much more input, there's argument that it's more derivative, I really struggle to grasp how humans learning to be creative aren't doing exactly the same thing and what makes that ok (except of course that's ok).
Maybe it's just less obvious and auditable?
Obsidian is close.
It's a little higher barrier to entry w.r.t. saving without a title, but it has a "Daily Note" feature that gets you very close to your quick need.
Benefit is that it's also really powerful if you want to get fancy.
