HomeFree

Inspiration

Feeling unsafe while walking home alone is an all-too-common experience. A quick call with a friend can bring comfort—but what if no one is available? HomeFree was created to ensure that no one ever has to feel alone in these situations. By combining AI-driven avatars with real-time safety monitoring, we aim to provide both reassurance and emergency response when needed.

What It Does

HomeFree is a web and mobile application that allows users to call or text an AI avatar when they feel unsafe.

Key Features:

Customizable AI Avatars – Users can choose avatars that resemble people they trust to provide comfort and guidance.
Live Video Calls – Real-time AI-generated video calls for a more engaging and calming presence.
AI Threat Detection – The app analyzes the video feed to detect potential dangers (e.g., weapons, suspicious activity).
Emergency Alerts – If a threat is detected, HomeFree can notify emergency contacts, share location, or call 911.
Seamless User Experience – Quick access through voice assistants like Siri (e.g., "Hey Siri, call Jake" directs to the app).

How We Built It

We combined cutting-edge AI, real-time video technology, and safety-focused design to bring HomeFree to life.

Cohere & OpenAI – Generate real-time AI text responses for user interaction.
HeyGen – Creates AI video avatars that interact naturally in live calls.
React (Next.js, Node.js) – Powers the web application.
Flutter – Enables a seamless cross-platform mobile experience.
Clerk – Secure authentication system for users.
TensorFlow & Flask – AI-driven video analysis to detect threats like weapons.
Google Maps API – Real-time geolocation tracking for safety monitoring.
Twilio – Sends WhatsApp messages, live location updates, and emergency calls when necessary.

Challenges We Faced

Elizabeth – First time working with TypeScript and Node.js, requiring a fast learning curve.
Edward – Faced challenges in optimizing the AI video interface for low latency.
Krishna – This was the most complex project he's ever built, pushing his technical and problem-solving skills.

Accomplishments We’re Proud Of

We successfully built a real-time AI video calling system that can monitor, analyze, and respond to potential threats—all within a single application. Seeing everything come together in just one day is something we’re incredibly proud of.

What We Learned

This project deepened our understanding of AI-driven video generation, real-time threat detection, and scalable cross-platform development.

How We See HomeFree Being Used

Helping night-shift workers get home safely.
Supporting university students walking home after late-night study sessions.
Providing an extra layer of protection for underserved communities and individuals at higher risk.

What’s Next for HomeFree?

Integration with Life360 & Siri for quick emergency activation.
Offline Availability – Ensuring HomeFree works even without an internet connection.
Wearable Compatibility – Quick access through smartwatches and voice commands.

Ethical Considerations

Privacy First – All AI models and personal data are stored locally on the user's device.
Encrypted Data Transmission – Any data processed by third parties is fully encrypted to protect user safety.

HomeFree is just the beginning—we’re committed to making personal safety accessible, intelligent, and effective for everyone.
