MIT AI2 Companion

MIT AI2 Companion is designed for users building apps with the MIT App Inventor web tool. It is not a stand‑alone app, and it only works when paired with your project in the browser. After installation, you connect your phone or tablet to your App Inventor session and see your edits reflected on the device. This setup suits classrooms and personal projects alike, and it keeps testing simple while you design. If you plan to download MIT AI2 Companion, confirm that your computer and device can join the same Wi‑Fi network.

MIT AI2 Companion features for testing apps

Live project viewing with instant updates

MIT AI2 Companion mirrors your App Inventor project on your device as you edit. Changes in the Designer and Blocks appear right away, so you can adjust layouts, logic, and interactions without rebuilding. This live view helps you confirm behavior as you work and spot issues early.

Quick connection with QR scan or code

To link your device to the browser session, MIT AI2 Companion supports scanning a QR code or entering a 6‑character code. You start the connection from App Inventor, then finish it in the Companion. This gives you a fast way to pair devices in classrooms or labs without extra steps.

Same Wi‑Fi requirement and basic troubleshooting

• Use the same Wi‑Fi network for your computer and device to allow discovery.

• Update the Companion if connection attempts fail or time out.

• Confirm the IP shown in the Companion matches your network and retry the link.

With these checks, most connection issues clear up quickly, and you can return to testing your app.

Direct APK option for sideloading

When store access is limited or unavailable, MIT AI2 Companion offers a direct APK for sideloading on Android. This option helps in schools, labs, or managed devices where installing through a store is restricted. Once installed, the Companion works the same way for live testing.

USB cable and emulator backups

If your network blocks Wi‑Fi discovery, you can test using a USB cable or the built‑in emulator from the main setup options. These paths keep development moving when wireless is not permitted. You can switch between methods as needed during your build.

Before you download MIT AI2 Companion

MIT AI2 Companion only works with the MIT App Inventor web tool, so plan to build and run your project in the browser. For the smoothest setup, ensure both your device and computer can join the same Wi‑Fi and that network discovery is allowed. In managed environments, consider the USB or emulator options ahead of time. Keeping the MIT AI2 Companion APK latest version installed helps avoid connection issues.

Support and classroom setup

For guidance, check the official “connect over Wi‑Fi” instructions on the MIT App Inventor site. This resource outlines the pairing steps, common error messages, and fixes that help in shared spaces. It also covers alternatives when Wi‑Fi does not work, which is useful for school networks.

How to use MIT AI2 Companion on Android

To get started, install the Companion and open your project in the App Inventor browser session. The basic link process is quick, and the live view shows your changes as you edit. If you download MIT AI2 Companion APK from APKPKure, the steps are the same.

1. Open your App Inventor project in the browser and choose Connect, then AI Companion.

2. On your phone or tablet, launch MIT AI2 Companion and allow any requested permissions.

3. Scan the QR code shown in the browser or type the 6‑character code to link the session.

4. Wait for your project to appear on the device, then edit your design and blocks to test changes live.

5. Keep both devices on the same Wi‑Fi; if the link fails, update the Companion or switch to USB or the emulator.

Start building and testing

MIT AI2 Companion helps you view and test your App Inventor projects directly on your Android device.
