Anthroid

Anthroid is a native Android app for mobile agentic workflows: a Claude Code-style agent that can work with your phone’s native capabilities (camera, voice, clipboard, notifications, app/URL launching, location/calendar, screenshots, and optional UI automation).

When it helps

• On-call / incident triage away from your desk: run quick diagnostics in a terminal, keep a chat thread with context, and resume the conversation later.
• Field work & device setup: scan QR codes to avoid retyping tokens/URLs, open links on-device, and copy/paste between apps.
• Hands-busy workflows: dictate messages with offline speech recognition so you can keep moving even with poor network.
• “What am I looking at?” troubleshooting: attach photos/screenshots for visual context, then follow a short step-by-step checklist.
• Phone-use automation: copy key info to clipboard, open deep links, launch apps, set reminders via notifications, and combine device context (location/calendar) with instructions.

Overview

Anthroid (Android + Anthropic) is a mobile implementation of Claude Code, designed around mobile-native input methods and device capabilities.

Design goals

• Device tools: access to location, calendar, clipboard, notifications, URL/app launching, and more.
• Mobile input: voice dictation (offline sherpa-onnx) and camera capture/QR scanning.
• Agent-style automation: optional overlay shows what the agent is doing when it operates outside the app.
• Terminal at hand: a full bash environment for advanced workflows.

AI Agent Tools

Claude can execute tools on your device:

Tool	Description
Bash	Run terminal commands
Read/Write/Edit	File operations
Glob/Grep	Search files and content
Notification	Show Android notifications
Clipboard	Read/write clipboard
Open URL	Launch browser
Launch App	Open installed apps
Location	Get GPS coordinates
Calendar	Query calendar events
Screenshot	Capture device screen
Screen Tap/Swipe	UI automation

Screen Automation Overlay

When Claude launches other apps or performs actions outside Anthroid:

• Floating banner appears at the top of screen showing agent status
• Streaming text displays what Claude is currently doing
• Stop button to cancel the operation at any time
• Auto-hides after task completion (tap to return to Anthroid)
• Requires overlay permission (Draw over other apps)

Terminal Environment

Built-in Linux terminal for advanced users:

• Full bash shell environment
• Package manager (apt/pkg)
• Node.js, Python, and more available
