I'd be curious to hear more. I presume you're using some kind of semantic search? Any other kinds of semantic technology? What kinds of insights into your journaling has it offered you/users?
I would say the insights frontier models have given me, at a high level, match some of those offered by professionals in a theraputic context--which is one reason I'd be curious to make an affordable/accessible app. Although I tread lightly into depersonalizing such a human area with techno utopian naivete...
Sounds very cool. Good luck with it!
