ChatGPT has its own app. Claude has its website. Gemini has Google's interface. But what if you could use any of these models right inside WhatsApp, where your conversations already happen?
With RunMyClaw and OpenClaw, you can. Your AI agent lives in WhatsApp and responds to messages like any other contact. No app switching, no browser tabs, no separate login.
Why Use AI Models on WhatsApp?
Convenience. WhatsApp is already open on your phone. Asking your AI a question is as easy as texting a friend.
Group access. Add the AI to a group chat and everyone in the group can interact with it. Great for teams, families, or communities.
Always available. Your AI agent runs 24/7 on a dedicated server. It responds whether you message at 2pm or 2am.
Any model, one place. Switch between Claude, GPT, and Gemini without switching apps. All models are accessible through the same WhatsApp chat.

Setup in 3 Steps
Step 1: Sign Up
Go to runmyclaw.ai, sign up with Google, and subscribe ($30/month). Your dedicated server is ready in ~60 seconds.
Step 2: Add Your API Key
Enter your API key from Anthropic (for Claude), OpenAI (for GPT), or Google (for Gemini). Your key goes directly to your server with zero-knowledge security. RunMyClaw never stores it.
Pick your model from the dashboard. You can add keys from multiple providers and switch between them.
Step 3: Connect WhatsApp
Click "Connect WhatsApp" in the dashboard. A QR code appears. Scan it with your phone's WhatsApp app (Settings > Linked Devices > Link a Device).
That's it. Send a message to your linked number and the AI responds.
