💡 Why LogWise?

🚨 The Problem:

Developers often struggle with:

• Endless .log files filled with stack traces, warnings, timestamps, and cryptic messages
• Manually scanning logs to debug production issues
• Missing key events hidden deep in noisy outputs

Logs are essential — but often overwhelming.

🧪 Sample Use Case

Upload this log file:

2024-07-01 12:02:15 WARNING Disk usage exceeds 85%
2024-07-01 12:02:18 ERROR Timeout occurred in UserService at line 45
2024-07-01 12:02:20 INFO Reconnecting to database...

→ You'll get an AI summary like:

1. Disk space is critically high.
2. A timeout error occurred in UserService.
3. A recovery attempt to reconnect was initiated.

🐳 Run Locally with Docker

# Start both frontend and backend
docker-compose up --build

Then open: http://localhost:5173
