Mika

Mika is an on-device AI agent for Android that operates apps and websites on a background screen to get things done.

Mika is an on-device AI agent for Android that takes a one-sentence request and carries it out on your phone. It drives apps on a private background screen, browses the web in a built-in browser, and runs scripts in a local Linux sandbox. Users bring their own model API key, choosing from supported preset providers or OpenAI-compatible, Anthropic, Gemini, or OpenAI Responses endpoints. It handles third-party apps by reading screens, tapping, and typing, and includes knowledge files for popular apps and websites. There is no Mika server, so requests go only to the configured model provider, and encrypted data is stored locally on the device.
