+
+**FinCaseAI** is an AI-powered credit dispute assistant that uses Perplexity's Sonar Reasoning Pro API to analyze financial dispute cases and suggest approve/reject decisions with detailed reasoning. It helps analysts by providing fraud detection, sentiment scoring, and urgency assessment for credit card dispute complaints.
+
+## Features
+
+* **Approve/Reject Decision Suggestions** with confidence levels and detailed reasoning
+* **Fraud Risk Scoring** using keyword and pattern matching algorithms
+* **Sentiment and Urgency Detection** from complaint text analysis
+* **Sonar API Integration** for intelligent recommendations and structured reasoning
+* **Optional Redis Caching** for improved performance and response times
+* **Structured Output** with citations and supporting evidence
+
+## Prerequisites

+- A brief explanation for the judgment  
+
+The API response is parsed and shown alongside internal fraud and sentiment scores for a complete picture.
+
+> **Example Prompt to Sonar**
