Taewan-P/gpt_mobile ? reverse-engineered prompt

Build me an Android chat app where I can talk to more than one AI model in the same place, and compare their answers side by side. I want it to support my own API keys for providers like OpenAI, Anthropic, Google, Groq, and Ollama, with a clean Material You style interface and dark mode. Let me adjust basic chat settings like temperature, top p, and the system prompt, and let me use custom API URLs and custom models too.

I also want chat history saved only on the device, with credentials kept secure. If possible, include optional tools for certain profiles, like web search and URL reading, plus support for connecting to MCP servers. Keep the app modern and polished, using Jetpack Compose, and make it feel fast and easy to use. If you need to check anything, look up the current docs online.
