Opendia

🚀 OpenDia

The open alternative to Dia / Perplexity Comet. Connect your browser to AI models without the need to switch browsers. It works seamlessly with Chrome, Firefox, and any Chromium browser, emphasizing privacy, local operation, and MCP focus.

If you are not technical or have never used MCPs before, we recommend using Perplexity Comet.

🚀 Quick Start

1. Install the Browser Extension

For Chrome/Chromium browsers:

1. Download opendia-chrome-1.0.6.zip from releases.
2. Extract the zip file to a folder.
3. Go to chrome://extensions/ (or your browser's extension page).
4. Enable "Developer mode".
5. Click "Load unpacked" and select the extracted folder.

For Firefox:

1. Download opendia-firefox-1.0.6.zip from releases.
2. Extract the zip file to a folder.
3. Go to about:debugging#/runtime/this-firefox.
4. Click "Load Temporary Add-on...".
5. Select the manifest.json file from the extracted folder.

⚠️ Important Note

Firefox extensions are loaded as temporary add-ons and will be removed when Firefox restarts. This is a Firefox limitation for unsigned extensions.

2. Connect to Your AI

Option 1: Double-click Installation (Recommended)

1. Download the opendia.dxt file from releases.
2. Double-click the .dxt file to install automatically.
3. The MCP will be added to your Claude Desktop configuration.

Option 2: Manual Configuration Add to your Claude Desktop configuration:

{
  "mcpServers": {
    "opendia": {
      "command": "npx",
      "args": ["opendia"]

🏗️ How It Works

graph LR
    A[AI Model] --> B[OpenDia Server]
    B --> C[Browser Extension]
    C --> D[Your Browser]
    D --> E[Any Website]

1. You ask your AI to do something browser-related.
2. AI calls OpenDia tools to understand and interact with pages.
3. OpenDia controls your browser through the extension.
4. You get results - AI can see what happened and respond intelligently.

🔒 Security & Privacy

• ✅ Your data stays private: Everything runs locally, and no cloud processing of your browsing data occurs.
• ✅ You control access: The extension only works when you want it to.
• ✅ Open source: Full transparency of what the code does.
• ✅ No tracking: We don't collect or store any of your information.

⚠️ Important Note

This tool requires broad browser permissions to function. Only use it with AI models you trust and in environments where you're comfortable with browser automation.
