Common Questions About Mazu
Have a question? Check our GitHub or submit an issue.
Why is Mazu 2.5GB in total?
The app itself is 210MB, but the Gemma 3n AI model is 2.3GB. This is a complete AI brain that runs on your device - no internet needed. Think of it as downloading all the emergency knowledge you'll ever need.
How does offline AI actually work?
Mazu uses Google's Gemma 3n model in GGUF format, which is optimized for mobile devices. All AI processing happens on your phone's processor - no cloud servers, no internet connection required.
Which emergencies does Mazu support?
Mazu is trained on Red Cross protocols and emergency response guidelines. It covers earthquakes, fires, floods, hurricanes, medical emergencies, power outages, and general disaster scenarios.
What about battery usage?
Mazu is optimized for emergency use. In standby, it uses minimal battery. During active use, it's comparable to using a messaging app. We recommend keeping your phone charged as part of emergency preparedness.
Can I trust Mazu's advice?
Mazu follows established emergency protocols from organizations like the Red Cross. However, it's an AI assistant, not a replacement for professional emergency services. When available, always call official emergency numbers.
Is Mazu really free?
Yes, completely free. No subscriptions, no in-app purchases, no ads. This is our submission for the Google Gemma Developer Contest, built to help people in emergencies.
