For me, the most intuitive answer is that the end product was created by a combination of you and the AI tool operating together. As every event in the universe is a result of multiple, or many, conditions or factors.
We often like to assign a single main cause to events by asking "what" (implying an inanimate source) or "who" (implying a human source) but these English constructs can be misleading.
This point of view might be seen as belonging to Linguistic Relativity or Linguistic Determinism.
