Document AI — Document Intelligence & RAG

Multimodal document intelligence platform combining TensorFlow computer vision for page layout segmentation with an offline, local LLM RAG pipeline in ChromaDB for private document querying.

💡 The Problem

Organizations process large volumes of unstructured PDF documents daily—invoices, financial audits, research papers, and technical manuals. Manually categorizing documents, extracting tabular data, and verifying specific clauses across multi-page files is slow and error-prone. Furthermore, sending confidential enterprise documents to public cloud AI APIs creates unacceptable data privacy and compliance risks.

🎯 The Solution

Document AI pairs deep learning computer vision (TensorFlow) with a fully offline LLM retrieval-augmented generation (RAG) pipeline. It automatically segments PDF page layouts, classifies document categories, extracts tabular structures, and indexes chunked embeddings into ChromaDB for instant, hallucination-resistant Q&A with complete local data sovereignty.
