Imagine you have a sheet with three columns.
E.g. Notes, requirement and rationale.
The notes field has no constrains, the requirement column is intended to contain the requirement extracted from the notes column and the rationale the motivation for the requrieement.
For this kind of scenario it would be useful to use AI in a workflow. "When triggered, get text from the Notes column, apply this AI command (defined in the workflow) , and put the results in these cells". Might need to be divided into several workflows, but the principle is the same.
