ZERO ONE command center

MOBILE · ANDROID & IPHONE

Use ZERO ONE on your phone.

Open the progressive web app instantly, install to Home Screen, or use the native Android / iOS Capacitor shells from source and CI builds.

Android note: the APK is cryptographically signed for sideloading, but it is not distributed or reviewed by Google Play. Prefer the PWA install for most users. iPhone tip: Safari → Share → Add to Home Screen.

DESKTOP · VERSION 7.8

Choose your computer.

No terminal required. Keep opened workspaces alive while switching services, use optional OS-protected login saving where supported, run the OpenZero Qwen3-1.7B Agentic local Assistant, check the inbox already visible in ZMail, open a compose window, and access the bundled ZSEC Shield.

Local model: Desktop 7.8.1 defaults to the approximately 1.1 GB OpenZero Qwen3-1.7B Agentic Q4_K_M through Ollama; model weights download separately on first setup. Unsigned-package notice: Windows SmartScreen or macOS Gatekeeper may warn until Authenticode/notarization ships. Prefer the GitHub release and verify SHA-256 checksums. The official latest release page is the source of truth.

01 / MOBILE

Phone-first workspaces

Tap into OpenZero, ZeroThink, ZMail and CallChat without juggling four bookmarks.

02 / DESKTOP

OpenZero-tuned local assistant

Desktop 7.8.1 keeps opened OpenZero, ZeroThink, ZMail and CallChat workspaces mounted as you switch. Its fast local Assistant now uses the verified OpenZero Qwen3-1.7B Agentic Q4_K_M model, can summarize the visible signed-in ZMail inbox, and can open compose; you review the message before pressing Send.

03 / TAB PILOT

Connect Chrome or Brave

Install the official OpenZero Tab Pilot extension, keep OpenZero running locally, then use one-click local connection. Each tab and consequential action still requires your approval.

Install from Chrome Web Store ↗

Inspectable source

Desktop and mobile shells are Apache-2.0. Security contracts and packaging locks are public.

SECURITY BOUNDARY

Strong defaults. Honest claims.

HTTPS for remote services, origin allowlists on desktop, OS credential storage for desktop tokens. ZSEC folder scanning is a desktop feature. No product can guarantee detection of every threat — keep your OS protections enabled.
