Kami — The Complete Guide

A personal AI assistant that lives inside WhatsApp — it listens, speaks, and remembers your conversations

Kami is a personal AI agent that lives inside WhatsApp — the messaging app we already use every day. Instead of opening yet another app like ChatGPT or Claude, you simply send a message to a WhatsApp number and get a reply, either in text or in voice. Under the hood, Kami is a service I built in TypeScript (the modern, type-checked version of JavaScript) that runs 24/7 on a small private server. It connects to WhatsApp through Green API — a lightweight, secure gateway that shuttles messages between WhatsApp and my code. When a message arrives, it is processed by Claude Sonnet — one of the most capable large language models (LLMs, AI systems trained to understand and generate text) on the market today. If the message is a voice note, OpenAI Whisper transcribes it into precise Hebrew; when Kami replies, it can answer with a spoken voice generated by Google Gemini TTS (free and natural sounding). Kami's signature ability is memory: it remembers older conversations using a specialized database (Qdrant, explained in its own guide), so you can pick up on an idea you started a week ago and continue from exactly where you left off. For me (Elad), Kami has become something like a chief of staff: it sends a morning briefing, reminds me of tasks, and handles my voice messages while I'm on the road. For you, the exact same architecture can power smart 24/7 customer support, a personal tutor that walks a student through their work, a digital family companion, or any other use case you can imagine for a conversational agent that lives inside WhatsApp.
