What it solves

OneBox is an all-in-one AI agent and toolbox for Android that eliminates the need to manually search for specific tools or memorize complex steps. It provides a centralized hub for over 90 built-in utilities—ranging from image editing and PDF processing to bookkeeping and file management—all controllable via a natural language AI assistant.

How it works

The app integrates a built-in AI agent that can understand user requests and invoke the appropriate local tools to complete tasks. It supports multiple mainstream LLMs via OpenAI-compatible API keys (including free tiers like Gemini or OpenRouter). The agent operates within the Android sandbox, ensuring that local tools run on-device and only the conversation with the chosen AI model is sent online. For long-running tasks, the app uses a native Picture-in-Picture (PiP) mode to keep the user updated on the agent's progress while they use other apps.

Who it’s for

Android users looking for a versatile, open-source productivity suite that combines a wide array of utility tools with an AI-driven interface for faster execution.
