+J4DocSearch: Unlock the Information Sleeping on Your PC
+J4DocSearch is an innovative document search and management solution that transforms the scattered documents on your PC into an efficient knowledge asset. You no longer have to wander through folders or remember specific file names to find important documents. J4DocSearch makes your work smarter and faster.
 
-J4DocSearch is a high-speed desktop document indexing and search tool designed for Windows environments. It monitors your local drives in real time and enables fast keyword-based search across supported document types.
+Key Features
+⚡️ Blazing-Fast Content Search: J4DocSearch directly analyzes the content of various document formats, including DOC, DOCX, PPT, PPTX, XLS, XLSX, HWP, HWPX, and PDF. Instead of vague file names like "last week's meeting minutes," you can find documents accurately with keywords contained in the content, such as "market share analysis."
 
-This standalone, lightweight application requires no external server or database. It is especially useful for users who manage a large volume of documents or frequently need to access document contents quickly.
+💎 Find Hidden Treasures in Emails: Don't miss a single file, including those attached in Outlook. Put an end to the inefficient process of digging through countless emails to find an important contract or report! J4DocSearch manages your email attachments perfectly.

+🖥️ Lightweight Design, Minimal PC Resource Usage: J4DocSearch operates quietly in the background and won't affect your PC's performance. It's optimized to use minimal resources during indexing, so it doesn't interfere with your other tasks.
