oxproxion: A Versatile LLM Chat Client for Android

oxproxion is an open-source Android chat application designed to address users' needs for flexible interaction with LLMs on mobile devices. It supports OpenRouter cloud models (aggregating OpenAI, Anthropic, etc.) and local models (Ollama, LM Studio, etc.), offering rich conversation management, role customization, tool integration capabilities, and a focus on privacy protection. This thread will introduce its background, features, technical architecture, and usage guide across different floors.

With the development of LLM technology, users' demand for AI conversations in multiple scenarios has grown, but existing interfaces are mostly limited to web pages or have single functions. oxproxion, developed by stardomains3, is specifically designed for Android, user-centric, supports interaction with cloud and local models, and provides flexibility and privacy protection options.

Cloud Model Integration

oxproxion deeply integrates OpenRouter (a unified LLM API gateway). Users can access top models like OpenAI and Anthropic by configuring an API key. The interface supports clicking to view model details and long-pressing to check remaining quota.

Local Model Support

For privacy or offline needs, it supports local services such as Ollama, LM Studio, llama.cpp, MLX LM, and Hermes Agent. Users can use them after deploying and configuring connection parameters.

• Conversation Management: Save/load sessions, import/export chat history
• Response Mode: Streaming (real-time display) / Non-streaming (full display)
• Multimodal: Support for image conversation and generation (some models)
• Role Customization: System message library management to shape AI personality
• Inference Settings: Adjust thinking level to balance quality and speed
• Preset Configurations: One-click application of model/system message combinations, support for external sharing
• Tool Integration: Read/create files, timers, alarms, calendar events, etc.
• Conversation Mode: Voice interaction (voice input + automatic reply reading)
• Export: PDF export (full/single entry), copy (text/Markdown)
• Personalization: Custom chat font
