Latchen

Latchen is a private memory system for two.

Not a chat app. Not another to-do list. Latchen is a quiet space where two people share what matters — and have it remembered.

Pairi is your shared AI. It learns about both of you over time, holds onto the things that matter, and helps you stay aligned without having to repeat yourselves. Mention an anniversary, a project, or how your partner takes their coffee — Pairi notices, remembers, and surfaces it when relevant.

Beyond Pairi, Latchen helps couples with the practical things:

— Shared calendar that overlays both partners' schedules in one view
— Lightweight expense tracking with quick settlement via Venmo
— A space for the memories, plans, and details that build up between you

Latchen is for established partners. Not for meeting new people, not for broadcasting your relationship to the world. A pair connects through a private invite code. No friend lists, no profiles, no algorithm deciding what you see.

Latchen Plus unlocks unlimited Pairi conversations and full memory access. Free users get ten Pairi conversations per week and full access to calendar, expenses, and memory features.

Your relationship is private. Latchen is built to keep it that way.
