Mika: A New Android AI Agent You Can Test Today

If you have ever wished your phone could just finish the boring task for you, you know the real cost: switching apps, tapping through menus, and re-checking everything by hand. That is the gap a new Android AI agent called Mika is trying to close. It runs on your device, opens apps on its own, and works through the web until the job is done, so we decided to dig into what changed and what to watch out for.

1. What's new with Mika

Mika is an open-source Android AI agent published on GitHub. According to the project page, it is "An AI assistant on your phone: say what you need, and it works your apps and the web until it's done." That is a broad claim, so we looked at how it actually does this.

The trick is a hidden background screen. Mika opens apps, taps, types, and scrolls there, while your visible screen stays free for you to keep using the phone normally. You can tap a small live view any time you want to check on it.

2. Who this helps

The repo lists demos that hint at the target user: people who want a single sentence to replace a chain of manual steps. Examples include summarizing a group chat, finding a charger under a price and rating threshold, or reading out the top stories on a news site.

It also helps people who juggle repetitive app chores, like greeting recruiters on a job site or comparing flight prices. Because this Android AI agent does not need app-specific integrations, it can, in theory, work with almost anything already installed on your phone.

3. Try Mika in 15 minutes

Start at the GitHub repository and read the README for your language; it is available in English, Chinese, Japanese, and Korean. Clone the project, since it is built with Kotlin and Jetpack Compose, and you will need Android Studio or a build setup that can run Gradle.

Next, you supply your own model access. Mika has no built-in server; instead you bring your own model API key, or sign in with a ChatGPT, xAI, or OpenRouter account. If you already use ChatGPT, that sign-in path is the fastest way to get moving.

Once it is installed, give it a plain-language task, such as reading your top recent chat messages, and watch the background screen do the work. Fifteen minutes is enough to get a first result, though your mileage depends on how comfortable you are compiling Android apps from source.

4. The catch

Here is the catch: this is a developer-facing project, not a polished consumer app from a store. You need to build it yourself, provide your own API key, and trust an agent with real control over your apps and accounts.

Because Mika reads the screen and finds buttons "the way a person does: no app APIs, no per-app integration," its reliability depends on how each app's interface looks. A redesigned app layout could trip it up. So treat early runs as a test, not a production tool, and supervise tasks that touch payments or messages.

5. How it actually works

Under the hood, Mika is built to remember your preferences and turn finished tasks into reusable skills, so repeated jobs should get faster over time. It also works inside its built-in browser: you can say what you want on the page you are reading, and it acts right there, stopping the moment you touch the page yourself.

All of this happens without a Mika-run server. Your data stays on your device, which matters if you are wary of agents sending screen content to a third-party backend. That said, the model you connect through ChatGPT, xAI, or OpenRouter still processes your requests on their end.

6. How it shows up in AI as a Game now

Mika showed up through our weekly radar scan and landed in the What's New feed and the changelog. It is not yet built into a fixed stepstone on any class path inside the game.

That means you will not find a dedicated Mika quest today. However, as we test it further, that could change, and we will track any updates through the same radar process that surfaced it.

Bottom line

Mika is a genuinely new kind of Android AI agent: open source, on-device, and app-agnostic by design. For developers comfortable building from source, it is worth 15 minutes to see it tap through a real task.

For everyone else, the catch is real: no store listing, your own API key, and a need to watch what it does early on. Browse our tools directory for more vetted options, or keep an eye on our blog as we follow how this one develops.
