AI Project Manager uses GPT-4 to transform high-level project goals into detailed plans. Users input objectives, and the agent automatically generates task breakdowns, sets milestones with time estimates, and prioritizes deliverables. It maintains a dynamic task list, allowing users to update statuses or reprioritize on the fly. All data is stored locally in JSON or Markdown format, enabling easy export or integration with other tools. Project Manager supports multiple projects, customizable templates, and CLI-driven interactions for quick iteration. It also provides summary reports and progress tracking, ensuring clarity on project health, deadlines, and resource allocation without manual spreadsheet management.
