GPT Mobile

GPT Mobile is an Android AI chat app for people who want to compare model responses in one conversation. It connects to your chosen providers using your own API keys and can work with models served through Ollama.

• Multi-model replies: Send a prompt to multiple models at once, with support for OpenAI GPT, Anthropic Claude, Google Gemini, Groq, and Ollama.
• Custom connections: Use custom model names and API addresses, and adjust system prompts and response settings for different conversations.
• Optional agent tools: Give selected provider profiles access to web search through Firecrawl, Perplexity, or Exa, URL reading, and tools from MCP servers; profiles stay chat-only until you assign tools.
• Agent activity: Run tasks in parallel, inspect saved execution traces, follow progress, and cancel work in progress.
• Local records: Keep chat history on the device, with credentials encrypted through Android Keystore and excluded from backups and exports.

The app is open source under GPL-3.0. It runs on Android; Ollama provides a connection to models you host, while cloud model providers and external search services receive the requests sent to them. Local chat storage doesn't mean cloud conversations stay on your phone. Opening the tool selector can also contact saved MCP servers for discovery and send their associated credentials.

The Material You interface supports dark mode and system colors, plus a separate app language setting on Android 13 and later.
