Your AI.
Your phone.
Corenyth runs on your Android phone. Your conversations, tasks and memories stay on-device, with no cloud model processing your requests.
Built with Flutter and open source, it pairs Qwen3 0.6B with llama.cpp for local inference. The model proposes actions; the app validates them before making changes.
Offline by design
The release app has no internet permission. Download the model in your browser and install it locally before using the AI.
Validated actions
Every proposed action is checked against a strict schema. Invalid model output is never executed; a rule-based planner handles the fallback.
Early prototype
Text chat, tasks, reminders, memory and the widget work today. Voice input and speech output are not integrated yet.
How it
works
From your request to a validated action. All on your phone.
You ask
Type a request in chat. Corenyth adds relevant memories and tasks to the context on your phone.
The local model proposes
Qwen3 0.6B runs locally through llama.cpp and proposes a structured action using grammar-constrained output.
The app validates
The app validates the action before execution. If the model is unavailable or its output is unusable, a rule-based planner takes over.

started
The essentials. Setup, privacy and what comes next.
How do I install Corenyth on Android?
Corenyth is an early open-source prototype. Follow the build instructions in the GitHub README to build and install the Android app with Flutter. The README covers the Android SDK, native model runtime and device requirements. Start there for the current setup steps.
Does the AI work without internet access?
Yes. After you download and install the model, Qwen3 0.6B runs on your phone through llama.cpp. Download the model separately in your browser and place it in Documents/localmodels using the instructions in the app. The release app has no internet permission, so conversations and AI requests do not need a cloud model.
Where are my tasks and memories stored?
Conversations, tasks, reminders and memories are stored locally on your Android device. Tasks and reminders use SQLite; memories use local full-text search to retrieve relevant facts and preferences. Android schedules reminder notifications so they can fire when the app is closed. Model actions are validated before stored data changes.
Are desktop, iOS and voice supported?
Android is the current focus. Desktop and iOS versions are future plans, with no release dates announced. The prototype supports text chat today; voice input and speech output are not integrated yet. Follow the GitHub repository for changes, setup documentation and the current feature status.
