🌪️ Aether

"When the great Peng bird journeys to the Southern Ocean, it flaps the water for three thousand miles, spiraling upward on a whirlwind (Aether/Fuyao) to ninety thousand miles, and travels for six months before resting."

Aether is dedicated to bringing a modern, local AI Agent experience to mobile and desktop devices (Android, iOS, and macOS). Built on top of the Pi framework, it pairs a minimalist, polished UI with immense extensibility, seamless tool calling, and full extension ecosystem support.

🧩 High Extensibility

Aether natively supports loading standard Pi Extensions. To bring TUI-oriented extensions seamlessly to mobile touchscreens, Aether provides a rich Extension API allowing extensions to inject custom settings cards, interactive composer widgets, overlay transcript viewers, prompt interceptors, and semantic tool titles.

* means it's an official extension adapted by the Aether team. Add your extension to the list by submitting a PR.

Extensions can be installed directly as zip packages in Settings → Extensions → Import extension.

For extension development documentation, see https://aether.baimoqilin.com/docs/extensions/overview.md.

📱 Visuals & Experience

Aether's UI and interactions are heavily inspired by excellent, mature applications like ChatGPT, Codex CLI/App, Gemini, and Poco Agent. Every animation and interaction detail has been carefully polished to break the stereotype that "open-source means cheap and unrefined."

✨ Core Features

• Stunning UI & Silky Smooth Interactions: Distilling the design essence of top-tier apps like ChatGPT to create a minimalist, modern, and elegant interface.
• Pi Harness Kernel: Powered by the Pi framework, providing the widest LLM provider compatibility and a lightweight, highly efficient Agent execution engine.
• Extreme Extensibility: Inherits Pi's complete extension model while providing Aether's proprietary Script Extensions and Native Mods system to deeply customize mobile UI, settings, composer widgets, and runtime behavior.
• Built-in Alpine VM: Includes an automatically installed Alpine Linux environment to run shell commands and tools out of the box.
• System File Manager Access (Android): After initializing Alpine, select Aether (Alpine) in the system Files app or SAF document picker's sidebar to browse the environment and /workspace, create, edit, rename, delete, or copy files between Alpine and device storage. Changes apply directly to the files used by proot. System mounts such as /dev, /proc, and /sys are excluded.
• Extensible Host Control: Supports optional Shizuku and Termux integration for direct device manipulation and automation. (Android only)
