Limiting the use of these tools requires explaining to your students where they are and are not appropriate. Perhaps you want to allow the use of these tools to brainstorm ideas, or to produce first drafts, but you expect the students to make substantial changes to the final product. Perhaps you want to allow use of these tools, so long as students include their prompts, and the unedited output, so they can demonstrate critical use of these tools.
Like the strategy of resisting these tools altogether, this strategy requires enlisting students in the shared project of using generative AI in a relatively small number of approved ways.
