The Ember Path
Cotidie now remembers — and writes back.
Morning letters — Each morning, a letter about what you wrote, ending with one question worth answering. Every letter is kept in your archive.
Keep the flame — A streak that forgives. Miss a night and your flame waits under the ash.
Embers — Earn them by writing. Spend them on inks, seals, an extra conversation, or a deeper look at your month.
A ritual a day — Nine quiet invitations that rotate. Each one opens a part of Cotidie you hadn't found.
Start without an account — Write first. Sign up when it's worth keeping.
Plus: notifications that finally understand your day, a redesigned first day, and dozens of fixes.
Already with us? Open the app — a welcome and 100 embers are waiting.
KISA: Cotidie now remembers — and writes back. Morning letters that end with a question. A flame that forgives a missed night. Embers you earn by writing and spend on inks, seals and deeper looks. A quiet ritual each day. And you can start writing without an account.
