Segment PDFs by Table of Contents with Gemini AI & Chunkr.ai

This workflow intelligently segments large PDF documents by first ingesting them via URL or manual input, then leveraging Chunkr.ai for advanced Optical Character Recognition (OCR) and parsing to extract structured text content. Gemini AI analyzes the document to identify or generate a hierarchical Table of Contents (ToC), capturing headings and their levels accurately even if no explicit ToC exists.

Once the ToC is established, the workflow matches content sections to each heading, producing segmented outputs that include the heading text, hierarchy level, and content in multiple formats (e.g., markdown, plain text). This modular breakdown transforms monolithic PDFs into manageable, context-aware chunks.

Key benefits include enhanced accuracy for AI agents navigating documents, improved RAG pipelines with precise retrieval, targeted extraction for analysis or summarization, and streamlined processing in downstream workflows. Ideal for HR document management, legal reviews, research, and content repurposing, saving hours of manual effort.
