📖 Project Description What if you could guide and be present for your loved ones, even when you are no longer physically there? E-Ternal is a smart, immutable digital memory vault designed to securely store and deliver multimedia files, spatial videos, personal letters, and voice notes to your loved ones at exact moments in the future (e.g., an 18th birthday, a graduation, or an anniversary). Unlike traditional, cold cloud storage solutions, E-Ternal humanizes legacy management. By integrating with Facebook, it seamlessly builds your inner circle and family tree. From there, an Empathetic Conversational AI Agent guides you through the process, memorizing your family's milestones and understanding the emotional context to orchestrate future deliveries effortlessly. E-Ternal is built for the Meta Global AI Developer Hackathon, blending human empathy with cutting-edge technology. ✨ Key Features 🤖 Empathetic AI Agent (Muse Spark Max): We replaced cold calendar forms with an intelligent conversational agent. The AI remembers family members and birthdays, letting users simply say, "Save this letter for my daughter's 18th birthday." The agent extracts parameters and handles the automated scheduling. 🥽 Immersive VR Legacy (Meta Quest): Memories are meant to be felt. E-Ternal is designed for spatial video formats. Our vision is that recipients won't just watch a video on a screen; they will put on their Meta Quest headset and enter a Mixed Reality environment to experience the real presence of their loved one. 🔒 Secure & Automated Trigger Delivery: Backend architecture designed to encrypt and lock capsules until the precise moment the delivery conditions are met. 🛠️ Tech Stack AI Orchestration: Muse Spark Max (Conversational Agent, NLP, Context & Memory) Database: [supabase] 🛡️ The Elephant in the Room: Blockchain & Data Permanence How do we guarantee a message won't be lost if a server shuts down in 20 years? Our future roadmap integrates Decentralized Storage Networks (e.g., Arweave/IPFS) and Smart Contracts on the blockchain. Once a memory is sealed, it becomes immutable. Its future delivery relies on an autonomous smart contract rather than a central database, ensuring your legacy is mathematically guaranteed to be delivered, completely independent of central server longevity.
