Your On-Device AI Assistant

| Demo | Quick Start | Release | Issues |

OmniBot runs directly on your Android device and combines chat, agent tools, local workspaces, and system integrations in one app. 🎉 Our iOS & macOS version: ViaVera

OmniBot is an on-device AI agent built with native Android Kotlin and Flutter. Instead of stopping at chat, it focuses on the full loop of understand -> decide -> execute -> reflect.

Core Capabilities

• Extensible tool ecosystem: Skills, Alpine environment, browser access, MCP, and Android system-level tools.
• System-level actions: Supports scheduled tasks, alarms, calendar creation/query/update, and audio playback control.
• Memory system: Short-term and long-term memory with embedding support.
• Productivity tools: Read and write files, browse the workspace, use the browser, and access the terminal.

Quick Start

Configure the app

Open the settings page from the left sidebar:

Then open the scenario model settings:

Note: Memory embedding requires an embedding model. For the best overall experience, the other scenarios should use multimodal or vision-capable models whenever possible.

The app usually initializes the Alpine environment automatically on startup, and you can also manage that environment from the same settings area.

Use Cases

Skills

You can ask OmniBot to install a skill by simply sending it the repository link. Recommended collection: https://github.com/OpenMinis/MinisSkills

Enable or disable skills from the skill repository:

Scheduled tasks

Scheduled tasks execute subagent flows. Alarms are reminder-only. A subagent can be assigned a complete task and behaves like a full agent.

Browser

Workspace

Remote Codex bridge

To use Codex mode with Codex running on a PC or Mac, start codex-bridge on the computer where the Codex CLI is installed and logged in:

npx @thuocean/codex-bridge

Choose the LAN address and token mode in the terminal setup UI, then scan the printed QR code from OpenOmniBot's Codex settings. For advanced options and troubleshooting, see the codex-bridge README.

Development Guide

Requirements

• Flutter SDK 3.47.2+
• JDK 17+
• Node.js 20.19+ or 22.12+ and pnpm 10.28.0 (for WebUI development)

Get the code

git clone https://github.com/omnimind-ai/OpenOmniBot.git
cd OpenOmniBot

cd ui
flutter pub get

If Flutter reports Could not read script '.../ui/.android/include_flutter.groovy', run:

flutter clean
flutter pub get

Develop the WebUI locally

The WebUI in webchat/ is a standalone React + TypeScript + Vite project. During local development, Vite serves the frontend with hot reload and proxies /webchat/api requests to the Android app's local service.

1. Install and start OpenOmniBot on an Android device. Keep the computer and device on the same trusted LAN.
2. In the app, open Settings > Local Service, enable the service, and copy its address and Token. The default port is 8899, but always use the address shown by the app.
3. Start the WebUI development server from the repository root, replacing the sample address with the Android local-service address (do not append /webchat):

cd webchat
pnpm install --frozen-lockfile

VITE_WEBCHAT_PROXY_TARGET=http://192.168.1.20:8899 pnpm dev

On PowerShell, set the proxy target first:

$env:VITE_WEBCHAT_PROXY_TARGET = "http://192.168.1.20:8899"
pnpm dev

Open the URL printed by Vite (normally http://localhost:5173) and enter the Token copied from the app. Use pnpm dev for end-to-end API/SSE testing; the proxy keeps session cookies, realtime events, workspace access, and browser mirroring on the same local origin.

Before submitting WebUI changes, run:

cd webchat
pnpm run typecheck
pnpm run build

The production files are generated in webchat/dist/. Both dist/ and node_modules/ are local outputs and must not be committed.

Android builds handle the WebUI automatically: Gradle runs the locked pnpm install, executes the Vite production build, clears stale WebChat assets, and copies only dist/ into the APK. To verify this step without building the full app, run:

./gradlew :app:syncWebChatBundle -Ptarget=lib/main_standard.dart

Flutter Web is not part of this workflow.

Build and install

Release APK builds use OMNIBOT_UPDATE_WORKER_URL as the default GUI VLM proxy and receive the Gelab route from the update Worker. The upstream Gelab key stays in the Worker. Debug APK builds use the OpenAI-compatible LLM API configured by LLMTHU_API_BASE, LLMTHU_API_KEY, and LLMTHU_MODEL for normal LLM requests, context compaction, and scene.vlm.operation.primary. For local acceptance testing, Release builds can explicitly enable -POOB_BUNDLE_LLMTHU_PROVIDER=1 to bundle the same LLMTHU_* configuration for use out of the box. Regular Release and CI builds do not bundle this configuration by default.

cd ..

./gradlew :app:installDevelopStandardDebug -Ptarget=lib/main_standard.dart

For acceptance testing on a physical device, use the repository's LLMTHU installation script. It enables the LLMTHU provider by default and reads the API key from LLMTHU_API_KEY in the current shell. If the key is missing, the script fails immediately instead of producing an unusable test APK. Regular Release and CI builds still do not automatically bundle the key.

export LLMTHU_API_KEY='your-api-key'
./scripts/install_release_llmthu_device.sh
