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.

Cross-platform desktop agent from Nous Research that connects to Telegram, Discord, Slack, WhatsApp, and more, with persistent memory, scheduling, and isolated sandboxing.

Hermes Agent is a desktop AI agent built by Nous Research that runs natively on macOS, Windows, and Linux. It's designed for people who want a single agent that works across their communication tools, handles recurring tasks, and actually remembers what it's done before.
The core idea is persistence. Most agents start fresh every session. Hermes maintains memory across conversations, auto-generates skills from past interactions, and builds up context about your projects over time. You don't have to re-explain things.
Where it connects:
What it can do:
Sandboxing is a genuine differentiator. Five execution backends (local, Docker, SSH, Singularity, and Modal) give you control over where code actually runs, with container hardening and namespace isolation. That matters if you're running automated tasks or untrusted scripts.
For teams or individuals already using LobeChat or similar multi-surface chat interfaces, Hermes takes a different angle: it's less about chat UI and more about an agent that operates autonomously across surfaces. Think of it as closer to an AgentOS approach, where the agent itself is the persistent layer.
It's free to use under the MIT license, with paid tiers through the Nous Portal for higher model access and monthly credits.
