What is CortexON?

CortexON is an open source general artificial intelligence agent system that can think and perform actions to automate routine tasks. It is inspired by advanced agent platforms such as Manus and OpenAI's DeepResearch, but unlike these platforms, CortexON is completely open source , making advanced AI technology accessible to everyone.



CortexON is developed by TheAgenticAI team, aiming to break the current situation where the latest AI breakthroughs are restricted by closed source code and paywalls, giving users data ownership and privacy control. The project is committed to building in an open environment and welcomes community contributions of ideas, feedback and code.


Core architecture and working principle

At its core, CortexON is a multi-agent AI system that integrates multiple specialized agents that dynamically collaborate to accomplish user-defined goals:


1. Web proxy : handles real-time Internet search, data retrieval, and Web interaction 

2. File Agent : Manages file operations, organization, data extraction and storage tasks 

3.Execution Agents : Execute tasks, manage workflow, and coordinate inter-agent communications

4. Coding Agent : Generate, debug and optimize code snippets in various programming languages 

5. API proxy : seamlessly integrate with external services, APIs, and third-party software to expand automation capabilities 


These agents collaborate with each other and combine their unique capabilities to efficiently automate complex tasks.


Key Features

CortexON provides a range of powerful features:

-  Advanced, context-aware research automation
