A personal AI assistant that connects to your existing chat apps and handles real tasks like email, calendar, and flight check-ins on your behalf.

OpenClaw is a personal AI assistant built to take action. It doesn't just answer questions. It clears your inbox, sends emails, manages your calendar, and handles tasks like flight check-ins, all triggered through chat apps you already use every day.
The core idea is that you shouldn't need a new app to talk to your assistant. OpenClaw works through WhatsApp, Telegram, Discord, Slack, Signal, and iMessage, so you interact with it wherever you already spend time. No dashboard to open, no new habit to build.
It connects to a wide range of services out of the box:
What sets it apart from most chat-based AI tools is the action layer. Many assistants can tell you what to do. OpenClaw does it. The integrations aren't read-only; it can send, create, update, and automate across connected services.
The project is open source and self-hostable, which matters if you're handing an assistant access to your email and calendar. You control where it runs and what it can reach. A companion menubar app is available for macOS users who want quick access without switching windows.
It's an independent project, not affiliated with Anthropic or any of the AI providers it connects to. That independence shows in the breadth of integrations rather than a walled ecosystem.
