🤖 Building a Private, Local WhatsApp AI Assistant with Node.js & Ollama

Hello, dev community! 👋 I’ve been working on a personal project lately: a WhatsApp AI Bot that actually keeps track of conversations. No more "forgetful" bots, and best of all: it runs entirely on my own hardware! 🧠💻 🛠️ The Tech Stack Runtime: Node.js 🟢 AI Engine: Ollama (Running Llama 3 / Mistral locally) 🦙 WhatsApp Interface: WPPConnect 📱 Database: SQLite for persistent conversation memory 🗄️ OS: Linux 🐧 🚀 The Journey The goal was to create an assistant that doesn't rely on external APIs like OpenAI. By combining WPPConnect with Ollama, I have full control over the data and the model. Here is the project structure: Bash user@remote-server:~/whatsapp-bot$ ls database.db # Long-term memory (SQLite) node_modules # The heavy lifters package.json # Project DNA server.js # The brain connecting WPPConnect + Ollama tokens/ # Session persistence (No need to re-scan QR) 🔍 Key Features Local Intelligence: Using Ollama means zero latency from external servers and 100% privacy.
