Project Story

Inspiration

Mental health crises don't wait for office hours. 1 in 5 adults experience mental illness yearly, yet 75% of mental health conditions go untreated. The 988 Suicide Hotline receives 4.8 million calls annually in the US alone, with wait times that can feel like an eternity during a crisis.

I built MindBridge AI because I believe everyone deserves access to compassionate support at 2 AM, during a panic attack, or whenever life feels overwhelming. Not as a replacement for professional help, but as a bridge - always available, never judgmental, ready to listen.

What it does

MindBridge AI is a multi-agent mental health support platform with:

🎙️ Voice Companion - Talk naturally using speech recognition, with responses spoken back using ElevenLabs for natural, empathetic voice synthesis. Different voices for different agents (calming for sleep support, grounded for crisis).

💬 Multi-Agent Chat - A triage system routes conversations to specialized AI agents:

CBT Agent - Cognitive behavioral therapy techniques
Sleep Agent - Insomnia and sleep hygiene support
Crisis Agent - Immediate assessment and de-escalation
Grounding Agent - Anxiety and panic grounding exercises

📝 Smart Journal - Write daily entries with AI-powered sentiment analysis (Cerebras) that tracks your emotional patterns over time.

📊 Insights Dashboard - View mood trends, session statistics, and query your data with natural language ("Show me entries where I felt happy").

📄 Document Upload - Store therapy resources with Vultr Object Storage, searchable via SmartBuckets RAG.

How we built it

Backend (Raindrop Platform):

14 microservices deployed on LiquidMetal Raindrop
SmartMemory for conversation context across sessions
SmartBuckets for document RAG search
PRIMARY_DB (SmartSQL) for structured data storage
All services communicate via Raindrop service-to-service calls

Frontend (Next.js 15):

Deployed on Vercel
shadcn/ui components for accessible, beautiful UI
Web Speech API for voice input
Real-time state management

External Integrations:

Cerebras - Ultra-fast AI inference for sentiment analysis and response generation
ElevenLabs - Natural text-to-speech with emotional tone
Vultr Object Storage - S3-compatible document storage
Stripe - Payment processing (test mode)
WorkOS - Authentication infrastructure

Challenges we ran into

Edge Runtime Constraints - Backend runs on Cloudflare Workers, which meant no TCP connections. Had to adapt all external API calls to HTTP-based services.
Multi-Agent Coordination - Building a triage system that correctly routes users to the right specialist agent based on crisis level and topic detection required careful prompt engineering.
Voice + AI Latency - Coordinating speech recognition → AI response → TTS synthesis without awkward pauses. Cerebras helped significantly with fast inference.
SmartMemory Learning Curve - Understanding the working memory vs episodic memory paradigm took experimentation to implement correctly.

Accomplishments that we're proud of

14 deployed services working together seamlessly on Raindrop
Real voice conversations with ElevenLabs - it actually feels like talking to someone
Multi-agent routing that intelligently escalates crisis situations
Natural language insights - asking "show my happiest journal entries" and getting real results
Built the entire platform solo in under a week

What we learned

Raindrop's SmartComponents (especially SmartMemory and SmartBuckets) dramatically simplify building AI applications
Edge computing constraints force better architecture decisions
Voice AI requires careful attention to latency at every step
Mental health AI needs extra care around safety - always provide crisis resources, never replace professional help

What's next for MindBridge AI

Real-time voice streaming - continuous conversation without push-to-talk
Therapist dashboard - allow mental health professionals to monitor patients (with consent)
Mobile app - native iOS/Android for always-available support
Crisis hotline integration - seamless handoff to human support when needed
Multilingual support - mental health support in every language
