🎯 What You'll Learn

This guide covers how to:

• Break free from browser-based AI limitations
• Use Gemini CLI, Claude Code, Codex, and opencode in your terminal
• Maintain persistent context across sessions with context files
• Deploy AI agents for specialized tasks
• Run multiple AI tools simultaneously on the same project
• Sync context files across different AI tools
• Build custom workflows for maximum productivity

🚀 Why Terminal AI?

Browser AI problems:

• Lost context after scrolling too far
• Multiple scattered chats across different platforms
• No file system access
• Copy/paste hell
• Limited control over your work

Terminal AI advantages:

• ✅ Persistent context - Your work lives in files, not chat windows
• ✅ File system access - Read and write files directly
• ✅ Multiple AI tools working together on the same project
• ✅ Complete control - Everything stored locally on your hard drive
• ✅ Professional workflows - Build custom agents and automation
• ✅ 10x faster - No more context switching or copy/paste
