Tips on making a Workflow Diagram

  1. Write a prompt describing the workflow

    using the written prompt. The AI will convert it into a structured, flowchart-style diagram showing the progression of tasks across phases.

  2. Refine the diagram with follow-up prompts

  3. Manually adjust the layout using GUI tools
    (also requires sign-in). Drag and drop elements to clean up spacing, align nodes, or improve the visual structure.
