The tool is a GitHub repository called "babyagi" which is a task management system that uses natural language processing (NLP) and AI to create and execute tasks based on previous task results and predefined objects. The system also allows users to prioritize and reprioritize tasks using openai's API and stores the results in a database called Chroma. The repository includes Python scripts, Dockerfiles, and requirements.txt files for installation, and its underlying code and features are continuously updated and improved by the development community. The tool is open-source and free to use.
