Explaining a process, mapping a service, or making a rough idea understandable during a discussion.
A good first step
Write the question at the top, draw only the main steps and decision points, then share the diagram or export it for discussion.
What to check
A sketch is not a formal specification. Add labels, ownership, and edge cases before using a diagram to guide a high-stakes process.
Access and pricing
Plans, access, and feature limits can change. Check the provider's current terms before relying on a feature or price.
