100% Private

Yes, all CSV processing happens 100% in your browser. Your files never upload to any server. Only regex generation requests are sent to OpenRouter AI, with no CSV data.

Fast Processing

Local browser processing for maximum speed.

AI Powered

The AI Assistant generates regex patterns from natural language descriptions. Just describe what you need (e.g., 'find emails') and the AI creates the appropriate regex pattern.
