I built this because I wanted a personal AI assistant that works where I already chat - WhatsApp. It handles:

- Voice notes → transcription + AI response - Images → vision analysis + answers - PDFs → extracts text + answers questions - Regular text messages

The interesting parts: - Multi-modal handling in one conversation thread - Session management across message types - Conversation history without a database (uses conversation context)

The LLM integration is abstracted so you can plug in whatever provider you want.
