Welcome to ETOS LLM Studio—a native AI client born out of a boring high school classroom that has ultimately evolved into a hardcore geek powerhouse. Here, AI is no longer a dull chatbox, but an all-around assistant seamlessly integrated into your digital life. Whether you want to awaken top-tier intelligence on your wrist at any moment, or build your exclusive local knowledge base and virtual personas on your phone, ETOS delivers an uncompromising, ultimate experience. [Core Highlights] Native Dual-Platform, A Universe on Your Wrist Deeply optimized for iOS and watchOS, refusing the compromises of watered-down versions. We have entirely rebuilt the chat interaction on Apple Watch, supporting streaming output, voice input, and complex concurrency, while achieving seamless real-time synchronization of configs, sessions, and tools across both platforms. Multi-Model Engine & Absolute Control Native support for mainstream providers like OpenAI, Anthropic (Claude), and Google (Gemini). We give the power back to you: customize request headers, dynamically configure model parameters, or even directly modify the raw JSON request body, satisfying a geek's desire for absolute API control. Memory Accumulation & Worldbook Engine Local RAG Memory: Your data belongs to you. Built with a fully local SQLite vector database supporting text chunking and embeddings, giving your AI genuine long-term memory. Worldbook Engine: Supports highly customizable character backgrounds, conditional triggers, and system prompt injections. Fully compatible with mainstream Worldbook formats, ready to unlock deep role-playing and immersive conversations anytime. Daily Pulse Break the passive "Q&A" deadlock. Every morning, the system synthesizes your long-term memory, recent conversations, and external signals to proactively generate high-value intelligence cards. These seamlessly transform into to-dos and chat prompts, forming a perfect positive feedback loop. Boundless Extension & Automation Fully integrated with MCP (Model Context Protocol), supporting remote tool calling and capability negotiation. Deeply integrated with Siri Shortcuts and connected with the local file system via URL Schemes, extending the AI's reach to every corner of your device. Supports dual-engine (System / Cloud) TTS (Text-to-Speech) reading, giving your AI a real voice. [About the Developer & Open Source Commitment] I am a high school student with a deep passion for computer technology. The original intention behind developing this app was simply that I was tired of the expensive and crippled AI software on the market. So, I decided to take matters into my own hands and build the ultimate client for my daily-use Mac and Apple Watch. Due to the extremely high Apple Developer annual fee, the App Store version charges a symbolic fee. Consider it a crowdfunding effort to help me pay off the debt, while you buy the convenience of not having to compile and tinker with it yourself. But technology should be shared; open source is my bottom line. The complete source code of ETOS LLM Studio (over 88,000 lines) is fully open-sourced on GitHub under the GPLv3 license. If you are also a geek who loves tinkering, you are completely free to pull the code, compile, and install it yourself for free. No matter how you found your way here, welcome to the world of ETOS. Are you ready to start the next conversation with your AI?
