+# 🧠 Omni Engineer: An AI-Powered Developer Console
+
+An intelligent assistant designed to enhance your development workflow with advanced AI capabilities.

 ## 🔍 Overview
-Omni Engineer is a console-based tool that integrates AI capabilities into your development process. It offers smart responses to coding queries, file management, web searching, and image processing functionalities.
 
-Omni Engineer is a spiritual successor to [Claude Engineer](https://github.com/Doriandarko/claude-engineer). It was built from my extensive usage of hand-made AI tools, trial and error, and feedback received. Compared to Claude Engineer, this new script allows for more control via simplicity while leaving some of the other functionalities like a fully automated flow, or the ability to run code. 
-At the same time, bring some cool new stuff like multi-file editing and save/resume of chats.
-I see this framework as more suitable for people who actually want to code with a better assistant on their side, versus something that is fully automatic.
