OpenCyvis turns Android into an AI phone. Give it a task in natural language — it sees your screen, understands the UI, and operates apps just like you would.

"Reply 'let's go eat sushi' in WeChat" — opens WeChat, finds the conversation, types and sends:

WeChat reply demo

"Find the best-rated coffee shop nearby and get directions" — opens Maps, searches, sorts by rating, taps navigate.

"Set a 7am alarm, turn on Do Not Disturb, and switch to dark mode" — chains Clock, Settings, and Display in one go.

It works in the background

Most AI tools lock your screen while they work. OpenCyvis operates on a virtual display — an isolated background screen. The AI books your flight while you scroll Twitter.

      You use this              AI uses this

Watch the AI work anytime. Take over if something looks wrong. Hand it back when you're done.

Why

When a company ships an "AI phone," they get full access to your screen, your apps, your messages — and you can't see what model is running, can't verify what data leaves your device, can't choose an alternative.

You should at least have the choice.

OpenCyvis is the open-source alternative: you see every line of code, you pick the AI model, you decide where your data goes. With a local model, nothing ever leaves your device.

Two Install Modes

Standard Mode

For most users. No custom ROM, no root, no computer.

Download and install the APK
Open the app, follow the setup wizard to complete ADB wireless pairing
Choose your LLM backend (cloud or local), start using

The entire pairing process completes on-device. Supports Android 11+.

System App Mode

For developers and power users.

Flash an AOSP system image. The app runs as a system application with full platform signing privileges. Screenshots use SurfaceControl directly — fastest possible. Full virtual display task management via system APIs.

How they relate

Same AI engine, same LLM backends, same UI, same capabilities. The only difference is how the app obtains system permissions. Standard mode uses ADB shell privileges; System App mode uses platform signing. For everyday tasks, you won't notice the difference.

v2.0 New Features

Remote Control via IM

Send messages to a bot in your IM app to control the phone's AI remotely. Currently supports Feishu and Telegram.

Use case: Install OpenCyvis on a parent's phone. Mom says "the text is too small" — you send "set font size to largest" in IM. The AI does it and sends back a confirmation screenshot. No need for both parties to watch the screen simultaneously.

Supports: sending commands, receiving progress, viewing screenshots, answering the AI's questions, stopping tasks. Pairing uses a 6-digit code.

Routines

Save frequent operations and run them on a schedule or with one tap.

Example: "Check calendar, weather, and unread emails every morning at 8am" — the AI runs automatically and pushes a summary to chat. Also supports geofencing — auto clock-in when arriving at the office.

Provider Profiles

Save multiple AI configurations (e.g., cloud Qwen, local Gemma 4, Claude) and switch between them with one tap. No need to re-enter API URLs and keys each time.

Dark Mode

Full day/night theme. Follows system settings or set manually. All screens — home, chat, settings, watch mode — have matching dark variants.

Multi-ROM Support

Standard mode now supports MIUI, ColorOS, OriginOS, and other vendor ROMs. Different manufacturers have vastly different wireless debugging entry points — OemHelper handles the differences.

Supported Models

OpenCyvis is model-agnostic. Bring your own AI account, connect a private service, or run a local model.

Cloud Models

Model	Latency per step	Pass Rate	Notes
Qwen 3.5 Plus	4-6s	4/4	Stable, recommended
Claude Opus 4	4-8s	4/4	Highest reasoning quality
MiMo v2.5	2.3-4.5s	4/4	Fastest
GPT-4o	3-6s	3/4	Occasionally ignores tool_choice

Local Models (via Ollama)

Model	Size	Speed	Pass Rate
Gemma 4 26B-A4B Q4	17 GB	63 tok/s	4/4
Gemma 4 E2B Q4	1.8 GB	41 tok/s	4/4
Qwen 3.5 35B-A3B Q4	22 GB	47 tok/s	3/4
Gemma 4 E4B Q4	3 GB	61 tok/s	3/4

Recommended: Gemma 4 26B-A4B — best balance of speed, quality, and memory.
Minimal: Gemma 4 E2B — just 1.8 GB, still passes all 4 tests.

Architecture

Both install modes share all upper-layer code. The difference is only in the privilege layer, isolated behind a PrivilegeBackend interface:

	SystemBackend	RemoteBackend
Privilege source	Platform signing (uid system)	ADB shell (uid 2000)
Input injection	InputManager reflection	AIDL proxy to PrivilegedService
Screenshot	SurfaceControl.screenshot()	ImageReader from VD Surface
VD task management	ActivityTaskManager reflection	PrivilegedService proxy

The backend is selected automatically at runtime.

Dual backend architecture

Privacy & Security

An AI agent with full phone access is one of the most privileged pieces of software you can run. This is not a place for "trust us."

You choose the AI service — hosted, private, or local
No telemetry, no analytics, no phone-home — zero tracking code
Open source — anyone can audit
Local model option — nothing leaves your device

Getting Started

Download

Two APKs are available on the Releases page:

APK	For	Package ID
`opencyvis-standard-release.apk`	Most users — install on any Android 11+ phone	`ai.opencyvis.standard`
`opencyvis-system-release.apk`	Developers — flash into AOSP as a system app	`ai.opencyvis`

Standard Mode (recommended)

Download opencyvis-standard-release.apk and install
Open the app, follow the setup wizard to complete wireless pairing
Configure your LLM provider in Settings
Start sending tasks

No root, no computer, no custom ROM required.

System App Mode

For developers building a custom AOSP image:

git clone https://github.com/opencyvis/opencyvis-phone.git
cd opencyvis-phone/android
./gradlew assembleSystemRelease

See android/README-AOSP.md for AOSP deployment and platform key signing.

Configure LLM

Set your provider in-app, or via deeplink:

# Local Ollama (fully private)
adb shell am start -a android.intent.action.VIEW \
  -d "opencyvis://config?provider=ollama&base_url=http://localhost:11434&model=gemma4:26b"

# Cloud API
adb shell am start -a android.intent.action.VIEW \
  -d "opencyvis://config?provider=openai&base_url=https://api.example.com/v1&api_key=YOUR_KEY&model=qwen-vl-max"
