Imagine a staff member who never sleeps, works across every app you already use, and handles emails, calendar, research, and follow-ups — all from a single text message. OpenClaw is a free, open-source AI agent you install on your own server. Connect it to WhatsApp, Telegram, Slack, or Discord, text it tasks, and it gets them done. It's not a chatbot that answers questions; it's an agent that takes action.
