挑战
Generic AI chatbots couldn't deliver the specialized, context-aware coaching fitness clients needed:
- Fitness questions (workout form, exercise selection) required different expertise than nutrition queries
- AI needed to remember past conversations, injuries, preferences, and progress
- Social scenarios (dining out, parties) required different dietary advice than meal prep
- Trainers needed tools to create and manage client programs at scale
我们的解决方案
We built a multi-agent fitness coaching platform where specialized AI agents handle different domains (nutrition, general fitness, social scenarios) with persistent memory.
Architecture
- AI Agent Service: Python/FastAPI with OpenAI GPT-4
- Long-Term Memory: Pinecone vector database for AI context persistence
- Short-Term Memory: Redis for conversational context within sessions
- Backend API: NestJS with PostgreSQL/TypeORM
- Mobile App: React Native/Expo with Zustand state management
- Web Apps: React 18 with Redux Toolkit and Ant Design
- Auth: Firebase Admin SDK + Google OAuth + OTP
Multi-Agent System
- Classification Agent - Analyzes incoming messages and routes to the right specialist
- Nutrition Agent - Handles diet questions, meal planning, calorie calculations
- General Fitness Agent - Exercise guidance, form tips, program adjustments
- Social Agent - Dining out strategies, event-specific dietary advice
- Follow-Up Scheduler - Automated check-ins based on conversation context
Key Features
- Intelligent Routing - Classification agent directs queries to domain specialists
- Persistent Memory - Pinecone stores long-term context (injuries, preferences, goals)
- Session Context - Redis maintains conversational flow within active sessions
- Automated Follow-Ups - Scheduled check-ins based on coaching conversations
- Multi-Platform - Mobile (React Native), Web (React), Admin dashboards
- Trainer Tools - Exercise library, training plan templates, client management
