How this works
This AI assistant handles incoming WhatsApp messages by retrieving relevant context from stored documents, generating thoughtful replies with GPT-4o, and responding via voice or text. It suits busy professionals and creators who need a reliable personal aide that remembers past conversations and manages daily tasks without constant oversight. The core step involves pulling conversation history and documents from Supabase, then feeding them into the language model for accurate, context-aware answers.
Use it when you require continuous, memory-backed support across multiple message threads. Avoid it for one-off queries or high-volume customer service, where simpler bots perform better. Common variations include swapping the voice output for text-only replies or adding calendar and email integrations.
