Contact Book vs an Obsidian contacts vault
An Obsidian-backed contact system is private, portable, and yours forever. It's also a pile of markdown that doesn't remind you to call anyone.
At a glance
An Obsidian contacts vault is appealing for the same reason a paper notebook is: portable, private, never going away. The cost is everything that requires active prompting - cadence reminders don't fire, life events don't surface, the Sunday review doesn't have an overdue list. Contact Book is what you reach for when the vault stops doing the work.
