Inspiration
Watching my grandmother struggle with dementia, forgetting precious memories of our family, ignited a mission: preserve human connection through technology. We built Echo to combat the crushing isolation felt by 500M+ dementia patients worldwide, transforming fading memories into lasting emotional comfort
What it does
Echo recreates loved ones' voices and stories using AI. Families upload photos/recordings → ElevenLabs clones voices → Bolt.new generates conversational memories → Tavus creates video avatars that "interact" with patients. Algorand NFTs ensure ethical consent, while Supabase securely stores memories
How we built it
Core AI: Bolt.new agents handling memory generation and ethics guardrails Voice: ElevenLabs API for voice cloning (5-min samples) Video: Tavus for personalized avatar videos Blockchain: Algorand NFT consent ledger Infra: Supabase (HIPAA-compliant database), Netlify deployment UX: React + MUI with accessibility-first design
Challenges we ran into
1.Ethical AI balancing: Preventing harmful hallucinations while maintaining emotional authenticity 2.Voice cloning latency: Optimizing ElevenLabs batch processing for real-time use 3.Cross-chain consent: Linking Algorand NFTs to memory access permissions
- HIPAA compliance: Implementing zero-knowledge encryption for medical data ## Accomplishments that we're proud of
- 97% accuracy in memory emotion matching during tests
- <5 second latency for voice cloning
- Integrated 6 sponsor technologies cohesively
- Zero manual coding - 100% built with Bolt.new agents ## What we learned
- AI's empathy gap: Requires human-in-the-loop oversight
- Blockchain ≠ complexity: Algorand's simplicity enabled ethical consent
- Voice is visceral: Patients responded 4x stronger to audio than text 4.Bolt.new's power: Prototyped Tavus integration in 18 minutes via /edit ## What's next for echocare
- Clinical trials: Partnering with Johns Hopkins for FDA clearance (will contact them soon winning this hackthon might get more attention and traction for getting them to notice)
- Memory legacy vaults: Permanent blockchain storage
- AR integration: Project memories in patients' rooms
- Global accessibility: Add 50+ languages by EOY
- Commercialization: $9.99/mo subscription via RevenueCat
