It's always interesting to me when I see someone build a complete personal system around functionality that to me would just be a text file, or maybe an org-mode file.

I Agree. LLMs chat assistant UI is more usable for this case. “My buddy Chris from fremont just got a promotion. Remember his new title and today’s date” is way easier than tapping a search query, filling forms, tabs and submit buttons.

For me it’s Notes.app, and I appreciate the notes being available offline and syncing across devices. Full text index is great.

I guess I’m lacking calendar invites, but I’ve been able to copy contents into AI to have it generate calendars for me.
