What Is OpenClaw? The Open-Source AI Agent, Explained

OpenClaw is an open-source AI agent — a program that runs continuously on a server, connects to your messaging apps, and acts on your behalf. If ChatGPT is a website you visit, OpenClaw is an assistant that lives where you already are: it answers you on WhatsApp at breakfast, monitors things while you sleep, and remembers yesterday's conversation tomorrow.

What makes it different from a chatbot

• It's always on. The agent runs 24/7 on its own server. You don't open an app — you message it like a person.
• It remembers. OpenClaw keeps memory across conversations and days. Tell it something once and it stays known.
• It acts, not just answers. Through skills — community-built extensions — it can search the web, manage calendars, scrape pages, generate images, track markets and thousands of other things.
• It's yours. The model, the memory and the conversations live on your instance, powered by an AI provider you choose — Claude, ChatGPT, Gemini and a dozen more.

A short history

The project went viral in late 2025 under the name Clawdbot, briefly became Moltbot, and settled on OpenClaw — the renames were trademark housekeeping, not a change of direction. Along the way it became one of the fastest-growing open-source projects in the AI agent space, with a skills ecosystem (ClawHub) that now counts tens of thousands of community-built extensions.

How people talk to it

OpenClaw connects to channels — the messaging surfaces where your agent listens. Telegram is the classic starting point, WhatsApp is where most people want it, Discord suits communities, and Slack plus a built-in Web Chat round it out. One agent can listen on several channels at once and keep a single memory across all of them.

What it needs to run

An always-on server and an AI provider. The server runs the agent's gateway; the provider (your API key or ChatGPT sign-in) does the thinking. That server requirement is the hurdle for most people — it's a real Linux machine that needs setup, security and updates, which is exactly the part ClawHost removes: a dedicated, pre-configured OpenClaw server, live in about a minute, managed from a dashboard.

Where to start

1. Get an instance running (deploy one on ClawHost, or set up your own server if that's your thing).
2. Connect a model — this guide helps you choose, and ChatGPT sign-in is the simplest if you already pay for Plus or Pro.
3. Connect Telegram first (it's the most reliable channel), then add the others.
4. Install a few skills and give your agent real work.
