Can You Reuse Someone Else’s AI Prompt? Credit, Copyright and Provenance
Quick answer
Usually yes, as a starting point. Under current U.S. Copyright Office guidance, typing a prompt does not make anyone the author of the image it produces, although an unusually creative prompt can be protected as a piece of writing. Learning from a prompt's technique is fine. Pasting its exact text into something you sell, or reusing the image itself, is where licenses and permission come in. When you know the source, credit it.
