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.

"Send a message to File Transfer": Mika's chat on the left, each step on its background screen on the right (4× speed; chat list blurred)
Get things done with one sentence
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
- Install: download the APK from Releases.
- 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).
- 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".

What it can do
| |
|---|
| Operate apps | Reads long lists and chat histories, taps and types, shares text into apps; hands logins, verification codes and payments to you |
| Browse the web | A built-in desktop-class browser that keeps you signed in, reads pages, downloads and uploads; paces itself and hands block pages to you |
| Your current screen | Double-tap the floating capsule to send the screen you're looking at: "how should I reply?", "note this down" |
| Schedules and conditions | "Remind me at 9 tomorrow", "do this every Friday"; runs on time in the original conversation |
| Jump in or stop anytime | Keep talking while a task runs to add or correct things (long-press to withdraw or edit one Mika hasn't picked up yet); after a stop it reports where it got to, and "continue" picks up from there |
| Hold to talk | Hold the chat input to speak and edit the words before sending; long-press the floating capsule to speak and release to send. Uses the phone’s built-in speech recognition, or a provider’s speech model if it has none |
| Files and computing | A Linux sandbox per conversation runs Python, Node and shell on the files you send (arm64) |
| From your computer | AI tools on your computer can hand Mika tasks through CLI + Skill or MCP (use Mika from a computer) |
By default Mika runs in Ask mode: it checks with you only before spending money (placing orders, paying) and just does everything else. You can switch to Autonomous mode instead. See Ask and Autonomous.
