# ownAI > ownAI is an open-source personal AI agent (Tauri/Rust, MPL-2.0) that runs > locally and builds a continuous relationship with its user: hierarchical > memory, self-programming (sandboxed tools and canvas apps), local models > via llama.cpp, or any API provider. Private by architecture: all data stays > on the device. Built toward capability sovereignty: communities training > models that belong to them. ## Library - [Who Owns Your AI?](https://ownai.com/agents/manifesto.md): the manifesto — borrowed independence, the guild principle, and our vision of federated training - [What your AI costs the planet](https://ownai.com/agents/carbon.md): how we estimate LLM emissions, how users see and reduce their own, and how we fund permanent carbon removal - [Carbon methodology](https://ownai.com/agents/carbon-methodology.md): the full estimation methodology with all constants and sources ## Product - [Download](https://ownai.com/download): installers for macOS, Windows, and Linux - [App source code](https://codeberg.org/ownAI/ownAI): MPL-2.0, development happens on Codeberg - [Privacy](https://ownai.com/privacy): what data exists and where it lives ## Optional - [Homepage](https://ownai.com): overview, features, credits service
