🤖 Terminai

An AI-enhanced shell wrapper that bridges natural language and command line

Terminai transforms your terminal experience by adding AI-powered command translation on top of your existing shell. Write commands naturally or use plain English - terminai understands both.

🎬 Demo

✨ Features

• 🔄 Seamless Shell Integration - Works as a wrapper around your existing shell (zsh/bash)
• 🤖 AI Command Translation - Failed commands automatically get translated from natural language
• 🛡️ Safety First - Always asks for confirmation before executing AI-generated commands
• ⚡ Smart Tab Completion - Complete file paths and commands just like your native shell
• 🔐 Secure API Management - Safely stores your Gemini API key with proper permissions
• 🎯 Enhanced Prompt - Clear [AI] indicator shows when AI features are active

🚀 Quick Start

Prerequisites

Node.js (version 16.0 or higher) must be installed on your system.

• Install via package manager (e.g., brew install node on macOS, apt-get install nodejs npm on Ubuntu)
• Download from nodejs.org

Installation

npm install -g @menguzat/termin-ai

Setup

1. Get a Gemini API Key from Google AI Studio

2. Launch Terminai

   terminai
   

3. Enter your API key when prompted (saved securely to ~/.terminai/config.json)

That's it! You're ready to use AI-enhanced commands.

💡 Usage Examples

Regular Commands Work Normally

[AI] user@hostname project % ls -la
[AI] user@hostname project % cd src/
[AI] user@hostname src % pwd

AI-Powered Command Translation

When a command fails, terminai automatically asks AI for help:

Simple Example:

[AI] user@hostname project % what's my wifi ip address
🤖 Command failed. Attempting AI translation...
🔄 Asking AI to translate the command...
💡 AI suggests: ifconfig en0 | grep inet | grep -v inet6 | awk '{print $2}'
❓ Execute this command? (y/N): y
✅ Executing AI-suggested command...
192.168.1.34

Complex Media Processing:

[AI] user@hostname project % use ffmpeg to replace the audio of video filename.mp4 with audio from audio.wav
🤖 Command failed. Attempting AI translation...
💡 AI suggests: ffmpeg -i filename.mp4 -i audio.wav -c:v copy -c:a aac -map 0:v:0 -map 1:a:0 -y output.mp4
❓ Execute this command? (y/N): y

Advanced File Operations:

[AI] user@hostname project % find all javascript files modified in the last 3 days and copy them to a backup folder
💡 AI suggests: find . -name "*.js" -mtime -3 -type f -exec cp {} backup/ \;
❓ Execute this command? (y/N): y

System Administration:

[AI] user@hostname project % show me all processes using more than 100MB of memory sorted by usage
💡 AI suggests: ps aux | awk '$6 > 100000 {print $0}' | sort -k6 -nr
❓ Execute this command? (y/N): y

Network Troubleshooting:

[AI] user@hostname project % check which process is using port 3000 and kill it
💡 AI suggests: lsof -ti:3000 | xargs kill -9
📝 Explanation: Find process ID using port 3000 and forcefully terminate it
❓ Execute this command? (y/N): y

Smart Tab Completion

[AI] user@hostname project % cp tsconfig<TAB>
tsconfig.json

[AI] user@hostname project % cd src/<TAB>
shell.ts  ai-service.ts  config.ts  cli.ts

[AI] user@hostname project % npm run <TAB>
build  start  test

Your support helps keep terminai free and continuously improving! 🚀

🔧 How It Works

1. Command Execution: Terminai first tries to execute your input as a regular shell command
2. AI Translation: If the command fails (non-zero exit code), it sends your input to Google's Gemini AI
3. Smart Suggestions: The AI interprets your natural language and suggests appropriate shell commands
4. User Confirmation: You review and approve the suggestion before execution
5. Safe Execution: The suggested command runs with full output, just like typing it yourself

🧠 Context-Aware Intelligence

Terminai automatically detects your development environment and provides smarter suggestions:

• Virtual Environments: Detects Python venv/conda/poetry environments and suggests appropriate activation commands
• Package Managers: Identifies npm/yarn/pnpm and uses the correct package manager for your project
• Project Types: Recognizes Node.js, Python, Git repos, Docker, and other development environments
• File Context: References actual files in your directory for more relevant suggestions

Examples:

# In a Python project with inactive virtual environment
[AI] user@hostname myproject % install pandas
💡 AI suggests: source venv/bin/activate && pip install pandas

# In a Node.js project with yarn
[AI] user@hostname webapp % add lodash as dependency  
💡 AI suggests: yarn add lodash

🛡️ Security & Privacy

• API Key Storage: Your Gemini API key is stored locally in ~/.terminai/config.json with user-only permissions (600)
• No Command Logging: Your commands and AI interactions are not stored or transmitted anywhere except to Google's Gemini API
• User Confirmation: AI suggestions always require explicit approval before execution
• Sandboxed Execution: Commands run in your current directory with your user permissions

🎯 Perfect For

• Complex Media Processing: FFmpeg operations, image manipulation, video conversion
• System Administration: Log analysis, process management, disk cleanup
• Development Workflows: Git operations, build automation, dependency management
• Data Processing: CSV manipulation, JSON parsing, text processing with awk/sed
• Network Operations: Port scanning, connectivity testing, firewall configuration
• File Management: Batch operations, recursive searches, permission changes
