Decima | AI-Powered Health Coaching Platform

Challenge: Decima’s development presented multiple challenges in AI integration, health data synchronization, compliance, and personalization at scale. It required flawless real-time processing while combining Whisper STT, ElevenLabs TTS, and LLMs for consistent persona-driven interactions. Continuous Apple HealthKit syncing demanded advanced algorithms to normalize inconsistent data. The system enforced proprietary health protocols while preventing hallucinations in LLM outputs through strict prompt engineering. Additional complexities included persona management, adaptive scheduling, and personalized content delivery aligned with evolving health goals. Solution: Kodexo Labs built a modular, HIPAA-compliant health coaching platform powered by generative AI and real-time analytics. It featured voice-based coaching using OpenAI Whisper and ElevenLabs for natural persona interactions. Health data was visualized through adaptive charts, and an Apple Calendar–integrated scheduler managed personalized tasks. The admin interface allowed persona creation and A/B testing, while a content alignment engine tailored wellness recommendations using keyword extraction. The system was built with React Native, FastAPI, AWS, and PostgreSQL for scalability and security. Results: The platform achieved a 70% increase in user adherence, improving daily engagement through personalized voice coaching and reminders. Data usability rose by 60%, turning complex metrics into actionable insights. Automated content delivery improved efficiency by 50%, aligning in real time with user behavior and goals. With 100% admin configurability, teams could adjust coaching tone, logic, and metrics independently, eliminating developer dependency and enabling continuous refinement.
