Inspiration
In times of global crises — whether natural disasters, armed conflict, or economic displacement — aid organizations often struggle with transparency, public engagement, and sustained support. At the same time, people around the world feel disconnected from these events, unsure how to help or whether their contributions are making a real difference.
We were inspired by the idea of bridging that emotional and logistical gap using technology: what if people could hear the stories of affected communities in deeply personal, AI-generated video form? What if donations were transparent, traceable, and programmable? What if storytelling could spark not just awareness but action — and be gamified for global engagement?
EchoAid was born out of this vision: a decentralized, AI-powered storytelling and aid platform that gives a voice to the voiceless and builds a global community around real-time, verified compassion.
What it does
EchoAid is a mobile-first platform that combines AI storytelling, blockchain transparency, and community gamification to power a new way of engaging with humanitarian efforts.
Here’s how it works:
Users subscribe to access compelling, emotionally resonant stories told through AI-generated video agents representing verified individuals or anonymized composites from war-torn or disaster-struck areas.
Each story is powered by ElevenLabs (for hyper-realistic voice synthesis) and Tavus (for face-synced video), allowing people to “meet” those affected in a deeply personal way.
RevenueCat is used to manage access tiers, where subscribers unlock richer stories, geospatial impact maps, or exclusive interactions like sending recorded “messages of hope.”
Donations are processed on Algorand via smart contracts, ensuring transparent, traceable, and trustless payments that go directly to NGOs, local recovery projects, or verifiably affected individuals.
Users can also generate their own AI peace messages, mint them as NFTs on Algorand, and post them in a dynamic “Wall of Peace.”
How I built it
Tools & Stack: Frontend: Built using React Native (for cross-platform mobile experience) and Tailwind CSS for clean UI.
Backend: Node.js + Next.js serverless functions handle the orchestration of API calls between AI services and Algorand smart contracts.
Voice AI: Integrated ElevenLabs API to generate human-like, emotionally resonant voiceovers for each script/story.
Video AI: Used Tavus API to create video agents that speak the scripts with lip-syncing and personality expression.
Subscriptions: Managed user subscriptions, paywalls, and access levels using the RevenueCat SDK (for both iOS and Android).
Blockchain: Used Algorand SDK to:
Distribute verified micro-donations to wallets representing NGOs or affected individuals.
Mint Peace NFTs.
Track and verify impact data using metadata on-chain.
Challenges I ran into
Coordinating Real-Time AI Generation: Tavus and ElevenLabs both have generation times that needed to be orchestrated properly. Handling retries, failures, and fallbacks for low-bandwidth users was crucial.
Humanitarian Authenticity: Ensuring the stories remained respectful and non-exploitative despite being AI-generated required ethical considerations and curation safeguards.
Blockchain-UX Bridge: Abstracting away the complexity of wallets, gas, and transactions while still using Algorand for transparency was a constant challenge.
RevenueCat Integration with Gamification: Making sure that access-based features didn’t conflict with free engagement pathways like Aid Quests required a flexible permissions system.
Accomplishments that I'm proud of
Built a working prototype that combines AI, blockchain, subscription monetization, and social gamification — all within a seamless user experience.
Created emotionally powerful stories through AI video that surprised even us — users felt connected to the characters and motivated to act.
Developed a smart contract routing system on Algorand that auto-distributes micro-donations to verified wallets.
Created a gamified user flow that made “doing good” feel like something fun, shareable, and communal.
What I learned
AI storytelling tools like Tavus and ElevenLabs can drive real emotional engagement when used thoughtfully — especially for global issues.
Subscription platforms like RevenueCat are not just for monetization — they can segment impact, motivate upgrades, and fund aid initiatives.
People want to help — but trust and emotional resonance are the biggest motivators. AI can help bridge that gap, if used ethically.
Blockchain rewards don’t need to be speculative — they can represent real, meaningful impact when transparently routed.
What's next for nil
Verified Partner Onboarding: Integrate directly with NGOs and on-ground aid organizations to verify story sources and wallet recipients.
AI Memory & Character Evolution: Introduce persistent AI personas (e.g., “Leila from Sudan”) whose stories evolve over time, learning from user interactions.
Multilingual Voice Expansion: Leverage ElevenLabs’ growing language support to deliver stories in local dialects.
AR Peace Murals: Use AR to let users project their minted Peace NFTs onto buildings or public places.
DAO for Community Governance: Let the EchoAid user community vote on where to direct surplus donations or what story themes to highlight next.
Marketplace for AI Stories: Let users create their own AI-generated “Compassion Capsules” that can be gifted, shared, or resold — with royalties going to aid.
