Mika

Mika is an open-source, on-device AI agent for Android by developer wangzan101 (王赞), published on GitHub on October 29, 2026. Instead of only chatting, Mika operates apps and the web on your phone to get things done—the author's demo opens Meituan, orders takeout and records the expense in a single flow.

Repo: github.com/wangzan101/Mika

Key points

1. Phone-use agent: drives Android apps through the accessibility layer (topics: accessibility, mobile-agent, automation, llm), written in Kotlin with Jetpack Compose.
2. Runs on the device as a private assistant rather than a cloud chatbot.
3. Traction: ~354 stars within roughly a day of creation; author's X demo ~10k views; picked up by Chinese tech accounts ("an interesting Android open-source project found on GitHub today").
4. Author's thesis: "phone use is already very strong; what's missing is a good product form"—core flows work, details still being polished.

Why it matters

Mika is part of the open-source wave of phone-use agents following AI phones from big vendors; the name is short and generic, so pair it with "Android AI agent" when searching.

How to try it

1. Clone or download a release from wangzan101/Mika and install it on an Android device.
2. Grant the accessibility permission it requests (needed to operate other apps) and configure your model/API as described in the README.
3. Start with low-risk tasks (search, notes) before letting it place orders or touch payments; review each action, as the project is very new.
