How I built a fully offline AI assistant on Android with Gemma 4 E2B
This is a submission for the Gemma 4 Challenge: Build with Gemma 4.
What I built
PocketClaw is an Android assistant that runs entirely on your phone. You can chat with it, talk to it (press and hold the mic, it transcribes live), show it photos, hand it a PDF and ask questions about it, or tell it to turn on the flashlight, set an alarm, open the dialer, send an SMS, drop something on the calendar, search the web, or fire a notification. All of that runs on a 1.5 GB model that lives on the device.
Once the model is downloaded the first time, you can switch on airplane mode. Nothing breaks.
