πŸ› οΈ Capabilities

OpenDia gives AI models 17 powerful browser tools:

🎯 Smart Page Understanding

  • Analyze any webpage - AI automatically finds buttons, forms, and interactive elements
  • Extract content intelligently - Get clean text from articles, social posts, or search results
  • Understand context - AI knows what type of page it's looking at and how to interact with it

πŸ–±οΈ Natural Interactions

  • Click anything - Buttons, links, menus - AI finds and clicks the right elements
  • Fill forms smartly - Works even on complex sites like Twitter, LinkedIn, Facebook
  • Navigate seamlessly - Go to pages, scroll, wait for content to load
  • Handle modern web apps - Bypasses detection on social platforms

πŸ“‘ Tab & Window Management

  • Multi-tab workflows - Open, close, switch between tabs automatically
  • Organize your workspace - Let AI manage your browser tabs efficiently
  • Coordinate complex tasks - Work across multiple sites simultaneously

πŸ“Š Access Your Browser Data

  • Bookmarks & History - Find that article you read last week
  • Current page content - Get selected text, links, or full page content
  • Real-time information - Work with whatever's currently on your screen

πŸ›‘οΈ Anti-Detection Features

  • Social media posting - Bypass automation detection on Twitter/X, LinkedIn, Facebook
  • Natural interactions - Mimics human behavior to avoid triggering security measures
  • Reliable automation - Works consistently even on sites that block typical automation tools

πŸ’¬ Example Prompts to Try

Once everything is set up, try asking your AI:

Content Creation:

"Read the article on this page and create a Twitter thread summarizing the main points"

Research & Analysis:

"Look through my browser history from this week and find articles about machine learning. Summarize the key trends."

Social Media Management:

"Check my Twitter bookmarks and organize them into categories. Create a summary of each category."

Productivity:

"Open tabs for my usual morning reading sites and give me a briefing of today's top stories"

Development Testing:

"Fill out this contact form with test data and check if the submission works properly"

Personal Assistant:

"Find that GitHub repo I was looking at yesterday about React components and bookmark it for later"

πŸ—οΈ 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

πŸ”’ Security & Privacy

Your data stays private:

  • βœ… Everything runs locally - No cloud processing of your browsing data
  • βœ… You control access - Extension only works when you want it to
  • βœ… Open source - Full transparency of what the code does
  • βœ… No tracking - We don't collect or store any of your information

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