OpenClaw on Signal: Private AI Messaging

Signal Integration

Signal is the most privacy-focused channel for OpenClaw. All messages are end-to-end encrypted, and combined with OpenClaw's local-first approach, your AI conversations are truly private.

Prerequisites

• A Signal account with a phone number
• Signal CLI installed on your system
• OpenClaw installed and configured

Setting Up Signal CLI

Signal doesn't have a public bot API, so OpenClaw uses Signal CLI — an unofficial command-line client.

Install Signal CLI

# macOS
brew install signal-cli

# Linux
# Download from the signal-cli GitHub releases

Register or Link

Option A: Register a new number

signal-cli -u +1YOUR_NUMBER register
signal-cli -u +1YOUR_NUMBER verify CODE

Option B: Link to existing Signal account

signal-cli link -n "OpenClaw"
# Scan the QR code with your Signal app

Configure OpenClaw

{
  "channels": {
    "signal": {
      "enabled": true,
      "number": "+1YOUR_NUMBER"
    }
  }
}

Privacy Benefits

• End-to-end encryption — Messages encrypted in transit
• Local processing — OpenClaw processes on your device
• No metadata — Signal minimizes metadata collection
• Open source — Both Signal and OpenClaw are fully auditable

Limitations

• Signal CLI can be less reliable than official APIs
• Group support is limited
• No rich formatting (Signal uses plain text)
• Linked device sessions may need periodic refresh

Best For

Signal + OpenClaw is ideal for:

• Privacy-conscious users who want AI assistance
• Sensitive conversations that need encryption
• Users who already rely on Signal as their primary messenger
