Hi Product Hunt, I'm Daniel. I built Diary BFF for the hour in bed when your head won't stop.
You write, and only when you tap Ask does your diary BFF write back, a few sentences right under your entry; when it brings up an earlier night, it adds the date.
Three things it does:
The diary has its own PIN, separate from your phone's passcode, and entries are not used to train AI.
On Sundays, your diary BFF writes you a letter about your week, the only time it writes to you without being asked.
You can export your diary any time, every entry with your writing and the replies.
You get 14 days to see if your diary BFF is worth it.
It's still early, so tell me what's missing.
A question for you: when you write at night, do you want a reply every time, or only on the nights you ask?
