As already explained, a personal intellectual creation is necessary for content to be protected by copyright. Your creative contribution and a certain level of creativity to the end result play a decisive role.
For example, if you change the arrangement of elements, adjust colors, or add new image elements, you could be considered the author of an image. However, if you have an advertising text created by AI and only change one word, this is not enough to be recognized as the author.
The more you modify the AI-generated content, the more likely you are to be considered the author. However, there is no absolute certainty. Even a very detailed prompt is not enough to claim copyright, as the content provided by the AI is unpredictable and random.
Important:
There is currently no clear case law or legal regulation in Germany regarding the authorship of AI-generated content. The planned AI regulation also does not contain any provisions in this regard. Therefore, it must be decided individually in each case whether a human has had enough influence on a text, image or video to be considered the author. If you want to adapt AI content in order to be considered the author, you should document these changes well.
If you want to ensure that you are considered the author, we recommend that you use the AI only as a source of inspiration and create the final product entirely yourself - and here too, to prevent later difficulties in proving it: document it.
