• Tech Stack: Python · Flask · LangChain · FAISS · Pinecone · Google Generative AI
• GitHub URL: Project Link

Project Overview
DocBrief is a web application that allows users to upload PDF documents, get concise AI-generated summaries, and ask questions to an intelligent assistant. The assistant retrieves accurate answers directly from the document content using vector search technologies.

Core Features

• Upload PDF files for processing
• Automatic document splitting and embedding generation
• Smart assistant for Q&A based on document content
• Real-time summaries and insight extraction
• Uses FAISS or Pinecone for efficient vector search
• Monitoring via LangSmith for observability

Example Use Cases

• For CVs: "What is the candidate's experience?"
• For research papers: "What is the main research question?"
• For reports: "Summarize the key findings."

Technologies

• Flask: For building the web interface
• LangChain: Document parsing and language model integration
• FAISS / Pinecone: Vector search for fast information retrieval
• Google Gen AI: For summarizing documents
• LangSmith: To track and monitor app performance

Customization
You can swap out the LLM (Google Gen AI) with OpenAI's GPT models or your own fine-tuned model by updating the summarization logic.
