🤖 Nova DevOps Assistant

Voice-First AI DevOps Assistant - Your SRE teammate that never sleeps

A hackathon project that transforms DevOps operations with natural voice commands and intelligent AI analysis. Built with Next.js, OpenAI Whisper, and a terminal-inspired UI.
Developed as part of Tech Europe London Hackathon on June 28, 2025. https://lu.ma/london-hack?tk=XOP0D6

✨ Features

🎤 Voice-First Interface

• Real-time voice commands with OpenAI Whisper transcription
• Natural language queries like "Show me error logs from the past hour"
• Hands-free operation perfect for incident response

🤖 AI-Powered Analysis

• Intelligent incident detection and root cause analysis
• Contextual responses based on system state
• Automated fix suggestions with confidence scores
• Security threat analysis and mitigation recommendations

📊 Real-Time Monitoring

• Live system metrics (CPU, Memory, Error rates, Response times)
• 100+ realistic log entries spanning 8 hours of activity
• 20+ incident scenarios from critical to resolved
• Time-based filtering and smart log aggregation

🎯 Demo-Ready Features

• Line-by-line result animations for impressive presentations
• Terminal-style UI with authentic DevOps aesthetics
• Comprehensive mock data simulating enterprise-scale infrastructure
• Professional incident response workflows

🚀 Quick Start

Prerequisites

• Node.js 18+
• npm or yarn

Installation

# Clone the repository
git clone <repository-url>
cd nova-devops-assistant

# Install dependencies
npm install

# Start development server
npm run dev

Visit http://localhost:3000 and start using voice commands!

Optional: Real Voice Transcription

For production-quality voice recognition, add your OpenAI API key:

# Create .env.local file
echo "OPENAI_API_KEY=your_openai_api_key_here" > .env.local

Optional: Weaviate Knowledge Base

For semantic search over 50+ DevOps runbooks and procedures:

# Start Weaviate (requires Docker)
./scripts/setup-weaviate.sh

# Or manually:
docker-compose up -d
curl -X POST http://localhost:3000/api/knowledge -H "Content-Type: application/json" -d '{"action": "initialize"}'

Note: The app works great without Weaviate using intelligent fallback search!
