Your Android Home Screen, Reimagined

The first multi-AI agentic launcher for Android. Say goodbye to context switching—your AI assistant lives on your home screen and can actually control your device.

Multi-AI Agent System

Not just chat—an AI that takes action. Saint John integrates OpenAI, Anthropic Claude, and Google Gemini with native device control capabilities. Your AI can launch apps, create notes, check weather, search the web, and access your calendar—all without leaving the conversation.

  • Agentic Skills — AI can launch apps by name, create notes, access device data
  • Web Search — Real-time information via integrated search (Tavily API)
  • Extended Thinking — See the AI's reasoning process in real-time
  • Rich Content — Markdown rendering, code syntax highlighting, image support
  • Multiple Models — Switch between OpenAI, Claude, and Gemini models dynamically
  • Tool Calling — Full function calling support across all providers
  • Streaming Responses — Real-time generation with ability to cancel mid-stream

Less Distraction, More Focus

Saint John is built on the belief that your phone should serve you, not distract you. Every feature is intentional. Every interaction is purposeful. No bloat, no clutter—just the tools you need, beautifully designed.

What You Need to Know

Saint John is free and open-source, but AI features require your own API keys from OpenAI, Anthropic, or Google. Your conversations and data stay on your device—we never see your API keys or chat history.

Web search requires a Tavily API key (free tier available). All other features work completely offline.
