Frequently Asked Questions

Is RAG Document Processor free?

Yes, PivaBox RAG Document Processor is completely free to use. There are no charges, subscriptions, or hidden fees. All processing happens locally in your browser.

Are my documents uploaded to a server?

No. All text processing and chunking happens entirely in your browser using JavaScript. Your documents never leave your device, ensuring your content stays private and secure.

What chunking strategy should I use?

Use <strong>Recursive</strong> for general-purpose documents as it tries multiple separators hierarchically. Use <strong>Sentence</strong> for narrative text, <strong>Paragraph</strong> for structured documents, and <strong>Fixed Size</strong> when you need exact character-level control. Overlap helps maintain context across chunk boundaries.
