## 🧠 Overview

**SmartBrief**, a low-code AI Document Summarizer is an enterprise-grade, low-code framework for AI-powered document summarization. I developed this platform to demonstrate how Microsoft Power Platform and Azure OpenAI (GPT-4o) can be seamlessly integrated to create production-ready AI solutions without extensive custom development.

This project addresses the critical business challenge of extracting key insights from large documents efficiently, enabling organizations to process hundreds of documents daily with minimal manual effort.

---

## 🎯 Objectives

Through this research and implementation, I aimed to:

- Evaluate the effectiveness of Retrieval-Augmented Generation (RAG) based summarization in a low-code environment
- Demonstrate seamless integration of Power Platform components (Power Apps, Power Automate, Dataverse) with Azure AI services
- Create a reusable and scalable architecture for AI-powered document processing within enterprises
- Achieve production-grade performance with 92% accuracy and sub-3-second processing latency

---

## 🧩 Architecture

![Architecture Diagram](https://raw.githubusercontent.com/rkneela0912/SmartBrief/main/images/architecture_diagram.png)

**Key Components:**

- **Presentation Layer:** Power Apps canvas application for document upload and summary viewing
- **Orchestration Layer:** Power Automate cloud flows managing the processing pipeline
- **AI Processing Layer:** Azure OpenAI (GPT-4o) with 128K context window
- **Data Layer:** Microsoft Dataverse for secure storage and audit trails

---

## 🛠️ Tech Stack

- **Power Apps:** User interface and interaction layer
- **Power Automate:** Workflow orchestration and business logic
- **Azure OpenAI (GPT-4o):** Core summarization using the latest multimodal language model with 128K context window
- **Microsoft Dataverse:** Enterprise-grade data storage with built-in security
- **AI Builder:** Document processing and text extraction
- **Azure Active Directory:** Authentication and authorization

---

## ⚙️ Implementation Steps

### Quick Start

1. **Dataverse Schema:** Create tables in Dataverse to store uploaded documents and their summaries
2. **Power App UI:** Design a user-friendly Power App with file upload control and summary gallery
3. **Power Automate Flow:** Build a flow that triggers on file upload, converts documents to text, calls Azure OpenAI API, and saves results
4. **Azure OpenAI Integration:** Configure GPT-4o deployment and connect to Power Automate
5. **Deployment and Testing:** Deploy the solution and test with various document types

### Detailed Guide

For complete step-by-step implementation instructions, see [Implementation Guide](docs/IMPLEMENTATION_GUIDE.md).
