AI Text Summarizer (.NET Windows Forms)

A professional desktop application built using C# and Windows Forms that leverages the Google Gemini 2.5 Flash API to provide instant, highly accurate text summarization. The application features a modern, side-by-side "Soft-UI" layout that allows users to toggle between paragraph and bullet-point summary formats.

📌 Project Overview

This project was developed as a practical programming assignment to demonstrate API integration, asynchronous programming in .NET, and advanced UI/UX design practices in desktop environments.

✨ Key Features

• Real-Time AI Summarization: Connects seamlessly to the Gemini 2.5 Flash model for fast and intelligent text processing.
• Dual-Format Output: Fully functional toggle buttons allowing users to choose between a cohesive Paragraph or structured Bullet Points.
• Modern Side-by-Side UI: A clean widescreen experience with separate panels for input and output to maximize readability.
• Automated Word Counter: Live character/word counters for both the input and result boxes.
• Smart Placeholders: Interactive text boxes that clear instructions automatically upon focus.
• Advanced Error Handling: Comprehensive try-catch blocks to gracefully handle network dropouts or API quota limitations.
