Zoen on iPhone: the Chats list with pinned plans and countdowns

Conversations that turn into something.

Zoen is a private messenger where friendships, relationships and communities form — and where people create apps and agents and share them with each other.
O mensageiro onde a vida acontece.

What Zoen does

A private messenger

Direct chats, groups and communities in one Chats list. End-to-end encrypted by default with MLS; offline-first; linked devices with history.

Live Pages and Plans

Documents the chat edits together — plans with budgets in exact cents, versions you can restore, all signed and synced.

Agents as members

Agents have their own identity, profile and invite link. They read only where they’re members and ask before acting.

Mini-apps

Small apps inside the chat on the open MCP Apps standard — booking, polls, lists, games — with state everyone sees live.

The app on iPhone

Chats: every conversation in one list, with plans pinned on top — Chats

A group chat with a hike countdown pinned on top — A group chat

Coastal Travelers, a community, in dark mode — A community

Writing a message, with the keyboard up — Writing a message

The first screen: Hi, I'm Zoen — Getting started

The barber’s booking bot

Bruno, a barber, describes the agent he wants. Zoen’s Creator agent builds it, Bruno approves it, sets his services and hours in his own words, and shares a link. Clients book free slots; Bruno is told about every booking and approves replies before they go out.

Your agent needs you: the agent shows Bruno its suggested reply before sending — “Your agent needs you”

How it’s built

flowchart LR
    Apps["iPhone · Mac · Android · Web"] -- "UniFFI / WASM" --> Core["One Rust core<br/>signed log · MLS · pages · grants"]
    Core <-- "Zoen Sync (protocol 4)" --> Relay["zoen-relay<br/>FoundationDB · Postgres · NATS"]
    Agents["zoen-agentd<br/>agents with their own devices"] <-- "MLS member" --> Relay

One Rust core powers every client, so behaviour is identical everywhere. The relay orders and delivers events it usually can’t read. Agents join chats as real, accountable members. Read the architecture →
