Executive Summary
Vision PDF is an AI-driven document processing platform that allows users to upload complex PDF files and extract all content from them, including images, text, and tables. The system converts this multi-modal content into vector embeddings and exposes it through a conversational chat interface. Vision PDF provides intelligent, context-aware answers to document-related queries in real-time using Vision AI and LLMs.
Challenges
Process mixed content(text,images,tables) only for complex PDFs.
ArrowRight
By preserving the context the visual elements have been extracted accurately.
Managing API costs of multiple AI services (LLMs, embeddings, Unstructured API).
Responses to be delivered Real-time streaming conversional
Maintaining separate stores for per-service data isolation.
Solution Overview
To handle all these challenges, GenAI Protos has developed a full-stack application. The system processes each uploaded PDF in parallel. The Unstructured API is used for high-resolution text and table extraction. Image analysis models capture visual content. All the extracted data is stored in a FAISS vector store (created per user) via embeddings. Queries are intelligently routed between OpenAI and Google Gemini LLMs, with built-in token usage and cost tracking. Reranking and contextual compression using a streaming chat interface are employed to ensure maximum relevance of responses.
