OpenClaw: Open Source AI

오래된 맥북에 설치하고 텔레그램으로 말 걸었더니, 자비스가 됐다.

Tested OpenClaw — a free, open-source personal AI agent — by installing it on an old MacBook (Retina 2017) as a dedicated agent machine, instead of running it on my main laptop.

OpenClaw runs locally and connects to messaging apps like Telegram, WhatsApp, and Discord. …

AI Agent with Gemini & Slack

이메일이 오면 AI가 읽고, 판단하고, Slack으로 알린다 — 사람 손 없이.

Built an agentic workflow that classifies incoming emails by urgency using Gemini, then automatically sends the result to Slack. The same 3-node pipeline was implemented three ways — n8n, LangChain, and LangGraph — to directly compare how each tool expresses orchestration.

The core architecture: Orchestration …
