+ClawDroid is an Android AI assistant with an embedded Go backend. Install the APK, launch, and start chatting — no separate server setup needed.
+
+A Kotlin/Jetpack Compose app provides the chat UI, voice assistant, and device automation. The Go backend runs as a single binary bundled inside the APK, handling the agent loop, tool execution, LLM calls, and messaging channels.
+
+<b>Features:</b>
+
+* Chat UI built with Jetpack Compose
+* Floating assistant overlay — replace Google Assistant with long-press home
+* Voice mode — continuous conversation loop (listen, send, think, speak)
+* Device automation — tap, swipe, text input, screenshot via AccessibilityService
+* 16+ built-in tools — file operations, web search, memory, cron, sub-agents, MCP
+* Multi-channel messaging — Telegram, Discord, Slack, WhatsApp, LINE
+* 10+ LLM providers — OpenAI, Anthropic, Gemini, DeepSeek, Groq, Mistral, Ollama, and more
+* Long-term memory and daily notes
+* Scheduled tasks with cron expressions
+* MCP (Model Context Protocol) server support
+* Customizable personality via workspace files
+
+<b>Two editions:</b>
+
+* Embedded — Go backend bundled in the APK, works out of the box
+* Termux — Run the Go backend separately in Termux for advanced users
+
+Requires an LLM API key (OpenAI, Anthropic, Gemini, etc.) to function.

+ClawDroidはGoバックエンドを内蔵したAndroid AIアシスタントです。APKをインストールして起動するだけですぐに使えます。サーバーの別途セットアップは不要です。
+
+Kotlin/Jetpack Composeアプリがチャット UI、音声アシスタント、デバイス自動操作を提供します。Goバックエンドはシングルバイナリとして APK 内にバンドルされ、エージェントループ、ツール実行、LLM呼び出し、メッセージングチャンネルを処理します。
+
+<b>主な機能:</b>
+
+* Jetpack Composeで構築されたチャットUI
+* フローティングアシスタントオーバーレイ — ホームボタン長押しでGoogleアシスタントの代わりに起動
+* 音声モード — 継続的な会話ループ（聞く→送信→思考→話す）
+* デバイス自動操作 — AccessibilityServiceによるタップ、スワイプ、テキスト入力、スクリーンショット
+* 16以上の組み込みツール — ファイル操作、Web検索、メモリ、cron、サブエージェント、MCP
+* マルチチャンネル — Telegram、Discord、Slack、WhatsApp、LINE
+* 10以上のLLMプロバイダー — OpenAI、Anthropic、Gemini、DeepSeek、Groq、Mistral、Ollama等
+* 長期メモリとデイリーノート
+* cron式によるスケジュールタスク
+* MCP（Model Context Protocol）サーバー対応
+* ワークスペースファイルによるカスタマイズ可能なパーソナリティ
+
+<b>2つのエディション:</b>
+
+* 組み込み版 — Goバックエンドを APK に内蔵、すぐに使える
+* Termux版 — 上級者向け、GoバックエンドをTermuxで別途実行
+
+動作にはLLM APIキー（OpenAI、Anthropic、Gemini等）が必要です。
