AI Assistant: More Than Just Feature Count
Plenty of toolbox apps are long on features. OneBox's built-in AI assistant saves you from hunting for tools and memorizing steps — just say what you want:
"Turn these images into a PDF." "Log this bill screenshot into my ledger." "Make me a to-do list." "Look up today's stock prices online."
It understands, acts, and reports back — in one flow.
- Bounded by its own permissions: everything the agent does stays inside the app's own Android sandbox and declared permission set — it never touches contacts, SMS or call logs; local tools run entirely on-device, and only the conversation with your chosen model goes online.
- An agent that drives the tools: the AI agent can invoke 90+ in-app local tools (PDF processing, image editing, file management, bookkeeping…), chaining multi-step tasks across tools — executed locally with per-tool timeouts and iteration limits.
- Picture-in-picture robot, no more waiting around: long agent task? Just leave the app — with an active AI session it drops into system picture-in-picture, where the mini-window robot keeps you posted on progress and one tap brings you back to the result. Native PiP, zero permissions required.
- One chat, many models: talk to multiple mainstream LLMs from a single entry, with custom AI engines and prompt management.
- Bring your own key — use it for free: drop in any OpenAI-compatible API key (including free tiers like Gemini or OpenRouter's free models) and the full assistant + agent is yours at zero cost. Custom engines, endpoints and tokens are fully open in the Google Play build and in builds from this repo.
- Transparent by source: every line is public — how data is processed locally and what never leaves the device is something you can verify, not a promise you have to trust.
