On correspondence,
and quiet
By the makers of Deck Mary · 2026
The day's mail used to arrive once. A pile on a wooden tray, opened with a knife, read with coffee. Now the mail arrives in ten places at once — and never stops.
Deck Mary is a return to that wooden tray.
Gmail. IMAP. Slack. Chatwork. Telegram. Discord. Instagram. WhatsApp. Teams. LINE. All read into one place, sorted by time, kept private to you. No team layer. No shared workspace. No notifications competing for attention.
We borrow a name from a captain's deck and a queen — Deck for the ordered surface where the day is read, Mary for the quiet companion who puts each letter in its place.
Three commitments
Quiet AI. Summaries are short. Drafts are polite. The model never claims certainty about a thread it has just read. Your judgment is the final draft.
Yours only. OAuth tokens are encrypted with AES-256-GCM before they touch the database. Row-level security walls every user from every other. We don't sell, we don't train, we don't share. Your archive belongs to you.
Personal scale. Deck Mary was made for one reader. There is no team plan, no admin console, no "collaboration suite." The inbox is a private room.
What we don't build
We don't build dashboards. We don't build engagement metrics. We don't add gamification, streaks, badges, or notifications you didn't ask for. We don't put a chatbot in the corner of every screen.
What we want, when we open our mail at the end of the day, is to read it, answer what matters, and close the lid. That is the entire product.
