Say anything on your mind and Serena finds a relevant Bible verse and podcast. Built with React Native and a Node.js backend.
The app uses Word2Vec embeddings to convert what you say into a vector, then runs cosine similarity against 5000+ distinct topics to find the best match. It also learns from past searches to improve recommendations over time.
