GPT Mobile is an Android chat application enabling simultaneous conversations with multiple large language models, including OpenAI, Anthropic, Google, and Ollama. It targets Android users who want a flexible, locally-managed AI client with a modern Material 3 and Jetpack Compose interface, allowing them to leverage their own API keys.

How It Works

The app utilizes official APIs for each supported LLM provider, allowing users to bring their own API keys. It supports customization of generation parameters like temperature and top-p, as well as system prompts and custom API endpoints/models. Chat history is stored locally on the device, ensuring privacy. The UI is built entirely with Kotlin and Jetpack Compose, adhering to modern Android development practices like a single-activity architecture and Material You dynamic theming.
