In one line

Diary BFF is a private iPhone diary that writes back when you ask.

In one paragraph

You write the way you’d write to a friend. The diary stays quiet while you write. When you tap Ask, your diary BFF answers in a few sentences, right under your words, and when a reply brings up an earlier night, it adds the date. Every Sunday, your diary BFF writes you a letter about your week. The diary opens with its own PIN, separate from the phone’s passcode, so an unlocked phone doesn’t open it. Entries are not used to train AI, and the replies aren’t written by a person.
