Orion

A multi-provider AI chat desktop app built with Tauri + Vue 3. Connect to Anthropic, OpenAI, Gemini, Qwen, DeepSeek, Kimi and more — all from one native desktop window. Conversations are stored locally and API keys are encrypted on-device.

This project was written entirely by AI (Claude). Every line of code — frontend, backend, encryption, streaming, UI — was generated through AI-driven development with no manual coding involved.

Getting Started

Prerequisites

• Node.js ≥ 18
• Rust (stable toolchain)
• Tauri system dependencies (macOS: Xcode Command Line Tools)

Usage

1. Add an API key — Click the Settings icon in the sidebar, pick a provider, enter your API key and save.
2. Start chatting — Go to the Chat view, click New conversation, choose a provider and model in the toolbar, then type and hit Enter.
3. Custom base URL — Every provider supports a custom API endpoint. Leave it blank to use the official default (useful for proxy setups).
4. Keyboard shortcuts — Enter to send, Shift+Enter for a new line, Esc to stop generation.
