Chunker AI

Chunker AI is an advanced document processing tool designed to break large documents into manageable chunks for AI-driven analysis, summarization, and content generation. It supports PDF and DOCX files up to 16MB and provides flexible chunking strategies to maintain context and optimize AI processing for books, ebooks, business documents, and other large text datasets.

How Chunker AI Works

1. Upload your document (PDF or DOCX, max 16MB).
2. Choose a chunking strategy (Character Count, Word Count, or Paragraph) or rely on semantic chunking to preserve context.
3. The AI processes the chunks sequentially, maintaining document structure and context across segments.
4. Retrieve processed text, side-by-side comparisons, or other output formats. All processing is performed in real time without server-side storage of your data.
