Cotidie
The AI journal that reads you back.
A journal that reads itself back to you. You write — a few sentences a night, in your voice. Cotidie reads them, slowly, and surfaces the patterns you'd been making without noticing. It does not generate. It does not score. It does not show you a feed. — 7 AI personas. Two free. One for every kind of night. — A Private Vault on your device. Never synced. Never seen by AI. — Voice dictation. Pattern insights. 10 languages. For the people who quit journaling at week three. iOS + Android. Free.
Hi Product Hunt 🤍
I'm Casper. I built Cotidie because I'm the worst journaler I know.
Every notebook I've started died at week three. Every "AI journal" I tried did one of three things that made me close it: generated content I'd never write, scored my mood out of ten, or shamed me for skipping a day.
So I built the opposite.
→ Cotidie doesn't write for you. You write a few sentences a night. The AI reads them — slowly, over weeks — and quietly surfaces patterns you'd been making without noticing. It hands you back what you'd already been writing.
→ There's a Private Vault that lives on your device only. Never synced. Never seen by the AI. Biometric-locked. Took us one stubborn month to wire that part right — and we have nothing to do with it after.
→ Seven AI personas. Sage when you want a guide. Kai when you want truth. Ash when you don't want a coach — just someone who sits with you. Not every night needs the same kind of company.
→ No streaks. No feed. No mood scores. No public profile. The rarest feature in 2026, honestly.
I'd love to know — what would make you actually keep a journal? And what would you want from one that reads itself back?
Thank you for reading. — c.
