Do you own what Claude writes?
Anthropic’s consumer terms say: "Subject to your compliance with our Terms, we assign to you all of our right, title, and interest, if any, in Outputs." As with every tool, being assigned those rights is not the same as the text being protected by copyright.
What this means for marketers
Anthropic assigns you the rights. Worth remembering that being assigned rights does not stop a competitor from generating something similar.
