How PDF Training Works

Vatdi uses optical character recognition and text extraction to read every page of your uploaded PDFs. The content is split into semantic chunks and stored in a vector database, enabling instant retrieval when a visitor asks a related question.

Best Practices for PDF Training

For optimal results, use text-based PDFs rather than scanned images. Organize documents with clear headings and structure. Remove duplicate or outdated files before uploading to keep the knowledge base clean and accurate.

Use Cases for PDF Chatbots

Product manuals, HR handbooks, legal documents, research papers, and training materials all work excellently as PDF training sources. Any document your team or customers frequently reference is a great candidate for AI training.
