Mobile Preview

The current iOS preview follows the real Codex mobile workflow: pair a phone, choose a workspace, continue a thread, then inspect the result.

Desktop pairing

The first-run flow connects the iPhone to a local Gateway page shown by the desktop runtime.

After pairing, the app surfaces connected devices, workspaces, project sessions, and projectless conversations.

Thread continuation

A Codex thread can be resumed from the phone while output and file changes are projected back into the mobile timeline.

Core Capabilities

Niuma is a mobile Codex companion for the actions that matter when a desktop Codex task is already running.

Pair with a desktop Gateway

Use the local Gateway QR code to establish device trust between iPhone and the desktop runtime without introducing an account layer.

Browse projects and sessions

Review connected desktops, workspaces, project sessions, and recent Codex threads from a compact mobile interface.

Continue Codex threads

Send follow-up input from iPhone to an existing Codex thread or start a new task while the desktop runtime stays the source of truth.

Handle approvals and files

Review task progress, approval details, file changes, and transfer-backed image or file content from the phone.

Workflow And Architecture

The architecture splits responsibility clearly: iOS owns the mobile experience, Gateway owns Codex runtime integration, and the Server stays a payload-blind control plane.

Security Boundary

Niuma is designed around a narrow trust boundary: the server routes encrypted control-plane traffic, but plaintext Codex content remains on the endpoints.
