Features

An AI That Actually Controls Your Phone

Not just a chatbot. CellClaw is a full autonomous agent with deep Android integration.

Autonomous Agent Loop

LLM-driven tool-use loop that thinks, acts, and iterates until the task is done. No hand-holding required.

Full Device Control

Tap, type, swipe, screenshot, launch apps, read screens — all via Android Accessibility in a separate process for stability.

SMS, Calls & Messaging

Read and send SMS, make calls, open WhatsApp/Telegram/Instagram chats, read and reply to messages across apps.

Computer Vision

Screenshots analyzed by vision-capable LLMs. See what's on screen, understand UI elements, and act on visual information.

Persistent Memory

Room database stores conversations, memory facts, and scheduled tasks. Your AI remembers context across sessions.

Long-Running Tasks

Heartbeat system with adaptive polling keeps tasks alive. Start an automation and walk away — CellClaw keeps working.

Wake Word Detection

Say "CellClaw" to activate hands-free. On-device TensorFlow Lite model — no cloud processing for wake word.

Custom Skills

Define reusable workflows in Markdown. Trigger keywords activate multi-step automations without reprompting.

How the Agent Loop Works

A simple but powerful cycle: think, act, observe, repeat.

You Send a Message

Via chat, overlay, notification, or wake word

LLM Thinks

System prompt + history + 33 tool schemas sent to your chosen provider

Checked against autonomy policy + app access control. Auto-approve or ask you.
