Mika

An AI assistant on your phone: say what you need, and it works your apps and the web until it's done.

It works on a hidden background screen, so you can keep using your phone.

Several demos use apps popular in China: WeChat is the main messaging app there, and Xiaohongshu (RED) is a lifestyle and social platform. Mika isn't tied to them; it works with any app or website on your phone.

 Why Mika

| | |
|---|---|
| 📱 Leaves your screen alone | Opens apps, taps, types and scrolls on a separate background screen while you use your phone as usual; tap the small live view whenever you want to watch |
| 🧩 Works with any app | Looks at the screen and finds buttons the way a person does: no app APIs, no per-app integration |
| 🌐 Call it from any web page | In the built-in browser, say what you want on the page you're reading and it works right there; touch the page and it stops |
| 🧠 Gets better with use | Remembers the preferences you tell it, and turns tasks it finishes into skills so next time is faster and steadier |
| 🔒 Your data stays on your phone | There is no Mika server; use your own model API key, or sign in with a ChatGPT, xAI or OpenRouter account |
| 🆓 Open source and free | Apache-2.0, all code public |

 Get started in three steps

1. Install: download the APK from Releases.
2. Connect a model: in Settings › Model, pick a provider and enter an API key, or just sign in with an account (models and sign-in).
3. To operate phone apps: follow the "Set up phone control" wizard in Settings and pair wireless debugging on the phone once (setup guide). Skip this if you only want chat, web and files.

Then try saying: "Set alarms for 9:40 and 10:00 tomorrow morning" or "Check the weather at 8 every morning and tell me only if it will rain".

 💡 Have a computer handy? Send this to the AI agent on it and it will set everything up for you:
